A spin-offs journey into achieving marketable products from bacterial cellulose

[Excerpt] Academic spin-offs, technological ventures born inside Universities, have increasingly strengthen the connections between the scholarship and the economy, by fostering the role of technology transfer and knowledge commercialization. This presentation will outline the major steps in taking an idea or a technology to market, growing the venture and aiming at securing a successful exit. Also, it will present BCTechnologies (Bacterial Cellulose Technologies), a spin-off from the University of Minho (Portugal). (...)

By-products of beer fermentation

Among the most important factors influencing beer quality is the presence of well-adjusted amounts of higher alcohols and esters; as well as the successful reduction of undesirable by-products such as diacetyl. While higher alcohols and esters contribute rather positively to the beer aroma, diacetyl is mostly unwelcome for beer types with lighter taste. Thus, the complex metabolic pathways in yeast responsible for the synthesis of both pleasant and unpleasant by-products of fermentation were given special attention in this last chapter.

Da metrópole ao enclave e vice-versa. A ideia de cultura num agente destacado do enclave galego de Lisboa: Alfredo Guisado

O enclave galego de Lisboa, escassamente estudado se comparado com os enclaves americanos, experimentou importantes mudanças de variado tipo entre finais do século XIX e primeiras décadas do seguinte. Seguindo o percurso de Alfredo Guisado (1891 -1975), proponho aqui algumas hipóteses acerca das relações que se estabeleceram entre o enclave e a metrópole, e dentro daquele, no plano cultural.

Desarrollo sustentable de Productos y Servicios de Camélidos orientados al mercado en la región andina (DECAM). Sustainable Development Products and Services Marketed oriented in Andean Region

Este proyecto cuenta con el financiamiento del sistema INCO de la Unión Europea e incluye 5 contrapartes europeas, y Bolivia y Perú como contrapartes americanos. Consta de cuatro paquetes: producto, mercado, difusión y coordinación. En el primer paquete se desarrollan fundamentalmente los aspectos relacionados con la carne fresca y los productos cárnicos tanto tradicionales como nuevos a desarrollar. Se realizan faenas protocolizadas y espontáneas comparando animales con distintos tratamientos nutricionales de edades entre 19-21 meses. Se realizan análisis de calidad de carne y paneles de degustación. Los productos tradicionales como el charqui se evalúan en su forma tradicional y se implementan sistemas mejorados como desecadores solares. Los chacinados no son tradicionales en el altiplano por eso se realizan en La Pampa con la idea de transferir la tecnología desarrollada. La evaluación de calidad de la carne incluye técnicas de evaluación del animal en pié como la conservación morfológica y la ecografía para predecir calidad de res en el animal vivo. Estas observaciones se corroboran a la faena donde se realiza toda la batería de evaluaciones de calidad de la res.

Transformacion de Productos Regionales mediante procesos catalíticos. Transformation of Regional products by catalytic processes.

En este proyecto se plantea la posibilidad de aumentar el valor agregado de compuestos abundantes en nuestro país (terpenos y glicerol) mediante reacciones de oxidación y transesterificación, reemplazando los procesos homogéneos existentes por procesos heterogéneos eco-compatibles. Para ello se desarrollarán catalizadores heterogéneos del tipo MCM-41 e hidroxidos de doble capa (HDC) que posean la función activa específica para estas reacciones bajo estudio.El limoneno, principal componente del aceite esencial de limón y los alfa- y beta- pinenos, presentes en el aceite de trementina, son materiales base ampliamente disponibles. Su oxifuncionalización catalítica, mediante reacciones de epoxidación u oxidación alilica, permite producir una gran variedad de productos como fragancias, agroquímicos, medicinas, etc. En tanto, se espera un marcado incremento en la disponibilidad de glicerol, subproducto de la producción de biodiesel. Mediante su transesterificación catalítica heterogénea es posible obtener selectivamente monoésteres, los cuales tienen importantes aplicaciones como emulsionantes o agentes de estabilización en la producción de fármacos, cosméticos y alimentos. El diseño y síntesis de los materiales catalíticos mencionados permitirá la obtención de productos químicos finos por métodos limpios con bajo impacto ambiental, atendiendo a los altos niveles de contaminación ambiental generados por los procesos homogéneos tradicionales.

Producción de factores de virulencia por fitopatógenos bacterianos de soja. Utilización de productos naturales como biocontrol. Production of virulence factors by soybean bacterial phytopathogens. The use of natural products as biocontrolers.

En Argentina el cultivo de soja ocupa el primer lugar en superficie sembrada. El 90% de la producción se obtiene en la zona central del pais. La siembra directa favorece la multiplicación y supervivencia de fitopatógenos causantes de tizón y pústula bacterianos. El tizón es producido por Pseudomonas syringae pv. glycinea observándose manchas marrones en las hojas. Produce gran variedad de toxinas: coronatina, faseolotoxina, siringomicina, tabtoxina, proteínas “nucleation ice”, entre otras, las cuales contribuyen a la clorosis y necrosis. En la infección, además, están involucrados exopolisacáridos (levano y alginato). La celulosa ha sido relacionada en la adhesión bacteriana y en la formación de biofilm. La pústula es causada por Xanthomonas axonopodis pv. glycines. Produce manchas pequeñas con una pequeña pústula de color claro. Libera enzimas como α-amilasa, proteasa, endo β-mannanasa, actividad peptolítica, que degradan componentes vegetales. Xantan, producido por X. axonopodis es uno de los componentes necesarios para la formación de biofilm. Este último es considerado un importante factor de virulencia porque proporciona una estrategia de colonización que otorga mayor resistencia a ambientes desfavorables, tolerancia a antimicrobianos, producción de metabolitos y exoenzimas, etc. Actualmente el control de bacterias fitopatógenas se realiza mediante pesticidas con alta toxicidad para los consumidores y el ambiente. Para evitar las bacteriosis en la práctica se sugiere la rotación de cultivos y utilizar semillas certificadas. Se están probando compuestos naturales derivados de plantas medicinales como pesticidas; estos se pueden dividir en varias categorías fitoquímicas. Varios estudios confirman la actividad antibacteriana, antifúngica y antiviral de estos productos. Extractos vegetales con alto contenido de flavonoides y aceite esenciales poseen una importante actividad antibacteriana. Además, algunos aceites esenciales podrían estar incidiendo en la liberación y/o producción de biofilm, exopolisacáridos y exoproteínas. La gran incidencia de las infecciones por fitopatógenos y las pérdidas económicas que estas acarrean hacen que su control presente grandes dificultades para la agricultura sustentable en soja de nuestro país. En este trabajo se propone estudiar los diferentes factores de virulencia de cepas bacterianas fitopatógenas y evaluar el rol que cumplen en el proceso de la enfermedad en cultivos de soja y desarrollar estrategias para el control de bacteriosis vegetales aplicando productos naturales aislados de plantas aromáticas. La correcta utilización de productos antimicrobianos de origen natural aplicados sobre el cultivo y/o sobre las semillas evitaría la dispersión de la enfermedad y la eliminación al medio ambiente de productos contaminantes no deseados. In Argentina, soybean cultivation occupies the first place; 90% of this cereal is produced in the central region of the country. Intensive tillage practices favour multiplication and survival of bacterial phytopathogens causing blight and pustule diseases. Pseudomonas syringae pv. glycinea produce several toxins like coronatine, faseolotoxine, siringomicine, tabtoxine and proteins of nucleation ice that contribute to the develop of chlorosis and necrosis, characteristic of bacterial blight. It also produces levan and alginate, cellulose and biofilm. Pustule disease is caused by Xanthomonas axonopodis pv glycines, which produce enzymes like α-amilase, protease, endo β-mannanase, peptolitic activity, xanthan and biofilm. Nowadays the control of phytopathogenic bacteria consists in the application of pesticides that are toxic for the environment and man. Natural products from medicinal plants are a new alternative for the treatment of phytopathogens. Researches made with phytochemical compounds (flavonoids, phenols, quinones, cummarines, essential oils, terpenes) support the antimicrobial activity of these natural products. What is more, these substances could suppress the biofilm, exoproteins and exopolisaccharides formation and release of them. The infections caused by phytopathogens provoke economical loses and its control presents big difficulties in our country. The proposal of this work is the characterization of phytopatoghenic strains, its virulence factors and the role they play in the disease process. The development of a new alternative for the control of vegetable bacteriosis using natural products obtained from aromatic plants and the correct application of them on sown fields or on seeds is also an objective in this work.

Green furniture: sustainable design guidelines for the Irish furniture and wood products industry.

This thesis presents the research and development of sustainable design guidelines for the furniture and wood products industry, suitable for sustainably enhancing design, manufacturing and associated activities. This sustainable guideline is based on secondary research conducted on subject areas such as ‘eco’ design, ‘green’ branding and ‘green’ consumerism, as well as an examination of existing certifications and sustainable tools techniques and methodologies, national and international drivers for sustainable development and an overview of sustainability in the Irish furniture manufacturing context. The guideline was further developed through primary research. This consisted of a focus group attended by leading Irish designers, manufacturers and academics in the area of furniture and wood products. This group explored the question of ‘green branding’ saturation in the market and the viability of investing in sustainability just yet. Participants stated that they felt the market for ‘green’ products is evolving very slowly and that there is no metric or legal framework present to audit whether or not companies are producing products that really embody sustainability. All the participants believed that developing and introducing a new certification process to incorporate a sustainable design process was a viable and necessary solution to protecting Irish furniture and wood manufacturers going forward. For the purposes of the case study, the author investigated a ‘sustainable’ design process for Team woodcraft, Ltd., through the design and development of a ‘sustainable’ children’s furniture range. The case study followed a typical design and development process; detailing customer design specifications, concept development and refinement and cumulating in final prototype, as well as associated engineering drawings. Based on this primary and secondary research, seven fundamental core principles for this sustainable guideline have been identified by the author. The author then used these core principles to expand into guidelines for the basis of proposed new Irish sustainable design guidelines for the furniture and wood products industry, the concept of which the author has named ‘Green Dot’. The author suggests that the ‘Green Dot’ brand or logo could be used to market an umbrella network of Irish furniture designers and manufactures who implement the recommended sustainable techniques.

Approved Drug Products with Theurapeutic Equivalence Evaluation - 34th edition

The publication, Approved Drug Products with Therapeutic Equivalence Evaluations (the List, commonly known as the Orange Book), identifies drug products approved on the basis of safety and effectiveness by the Food and Drug Administration (FDA) under the Federal Food, Drug, and Cosmetic Act (the Act). Drugs on the market approved only on the basis of safety (covered by the ongoing Drug Efficacy Study Implementation [DESI] review [e.g., Donnatal® Tablets and Librax® Capsules] or pre-1938 drugs [e.g., Phenobarbital Tablets]) are not included in this publication. The main criterion for the inclusion of any product is that the product is the subject of an application with an effective approval that has not been withdrawn for safety or efficacy reasons. Inclusion of products on the List is independent of any current regulatory action through administrative or judicial means against a drug product. In addition, the List contains therapeutic equivalence evaluations for approved multisource prescription drug products. These evaluations have been prepared to serve as public information and advice to state health agencies, prescribers, and pharmacists to promote public education in the area of drug product selection and to foster containment of health care costs. Therapeutic equivalence evaluations in this publication are not official FDA actions affecting the legal status of products under the Act.
