Studies on the chemical and nutritional quality of protein powders isolated from shrimp waste

Protein powders were prepared from processing waste of prawns either by mechanically squeezing the shell and freeze drying the resultant aqueous extract or by treating the shell with 0.5% sodium hydroxide, filtering it and freeze drying the filtrate. Comparative studies on the proximate composition, amino acid profile, consumer acceptability and nutritional quality of the protein powders showed that the product prepared by freeze drying of the press liquor obtained by passing the waste through a hand operated expeller is better in all aspects studied than the product prepared by mild alkali extraction.

Moved by spirit of Canadian nature

A travel article about a visit to Klemtu and the Great Bear Rainforest, British Columbia. A LOW-TIDE mark of rocks coated in orange seaweed borders the islands of the Great Bear Rainforest. Our seaplane stays low under the clouds. As we approach the village of Klemtu, turning into Finlayson Channel, the trees beneath us thicken against the shoreline like a concert crowd being pushed from behind. There's no gap between the dark, still sea and the front row of soaring conifers, seemingly no entry point into one of the last great wilderness areas.

The spirit of palliative practice:A qualitative inquiry into the spiritual journey of palliative care physicians

Objective: Much is known about the important role of spirituality in the delivery of multidimensional care for patients at the end of life. Establishing a strong physician-patient relationship in a palliative context requires physicians to have the self-awareness essential to establishing shared meaning and relationships with their patients. However, little is known about this phenomenon and therefore, this study seeks a greater understanding of physician spirituality and how caring for the terminally ill influences this inner aspect. Method: A qualitative descriptive study was used involving face-to-face interviews with six practicing palliative care physicians. Results: Conceptualized as a separate entity from religion, spirituality was described by participants as a notion relating to meaning, personal discovery, self-reflection, support, connectedness, and guidance. Spirituality and the delivery of care for the terminally ill appeared to be interrelated in a dynamic relationship where a physician's spiritual growth occurred as a result of patient interaction and that spiritual growth, in turn, was essential for providing compassionate care for the palliative patient. Spirituality also served as an influential force for physicians to engage in self-care practices. Significance of results: With spirituality as a pervasive force not only in the lives of palliative care patients, but also in those of healthcare providers, it may prove to be beneficial to use this information to guide future practice in training and education for palliative physicians in both the spiritual care of patients and in practitioner self care.

Enhanced bio-decolourisation of acid orange 7 by Shewanella oneidensis through co-metabolism in a microbial fuel cell

The decolourisation of acid orange 7 (AO7) (C.I.15510) through co-metabolism in a microbial fuel cell by Shewanella oneidensis strain 14063 was investigated with respect to the kinetics of decolourisation, extent of degradation and toxicity of biotransformation products. Rapid decolourisation of AO7 (>98% within 30 h) was achieved at all tested dye concentrations with concomitant power production. The aromatic amine degradation products were recalcitrant under tested conditions. The first-order kinetic constant of decolourisation (k) decreased from 0.709 ± 0.05 h−1 to 0.05 ± 0.01 h−1 (co-substrate – pyruvate) when the dye concentration was raised from 35 mg l−1 to 350 mg l−1. The use of unrefined co-substrates such as rapeseed cake, corn-steep liquor and molasses also indicated comparable or better AO7 decolourisation kinetic constant values. The fully decolourised solutions indicated increased toxicity as the initial AO7 concentration was increased. This work highlights the possibility of using microbial fuel cells to achieve high kinetic rates of AO7 decolourisation through co-metabolism with concomitant electricity production and could potentially be utilised as the initial step of a two stage anaerobic/aerobic process for azo dye biotreatment.

Studies on productivity and characterization of polygalacturonase from Aspergillus giganteus submerged culture using citrus pectin and orange waste

Polygalacturonases are part of the group of enzymes involved in pectin degradation. The aim of this work was to investigate some of the factors affecting polygalacturonase production by an Aspergillus giganteus strain and to characterize this pectinolytic activity. Several carbon sources, both pure substances and natural substrates, were tested in standing cultures, and the best results were obtained with orange bagasse and purified citrus pectin. on citrus pectin as sole carbon source, the highest extracellular activity (9.5 U/ml and 40.6 U/mg protein) was obtained in 4.5-day-old cultures shaken at 120 rpm, pH 3.5 and 30 degrees C, while on orange bagasse, the highest extracellular activity (48.5 U/ml and 78.3 U/mg protein) was obtained in 3.5-day-old cultures shaken at 120 rpm, pH 6.0 and 30 degrees C. Optimal polygalacturonase activity was observed in assays conducted at pH 5.5-6.5 and 55-60 degrees C. The activity showed good thermal stability, with half-lives of 90 and 30 min when incubated at 55 and 60 degrees C, respectively. High stability was observed from pH 4.5 to 8.5; more than 90% of the activity remained after 24 h in this pH range.
