Apresentação de proposta de ação institucional e seus fundamentos teóricos e metodológicos para a formação de professores de História. Enfoque na elaboração de material didático, nas atividades de ensino e aprendizagem e na avaliação sobre as questões ambientais presentes no conhecimento histórico escolar, nas práticas de pesquisa e educação ambiental. As experiências foram desenvolvidas em 2002-2003 pelo projeto História e Meio Ambiente: estudo das formas de viver, sentir e pensar o mundo natural na América portuguesa e no Império do Brasil (1550-1889), junto ao Núcleo de Ensino da Faculdade de Ciências e Letras da Unesp, em Assis/SP.

In a previous work a strain of microorganism was isolated in Araraquara region, SP, Brazil, and characterized as being Streptomyces sp. Ar386, producer of 26-deoxylaidlomycin and of more three polietheric antibiotics. In this paper there are presented studies about fermentation characteristics of the antibiotic performed in incubator agitator utilizing various cultivation technics and media. A medium containing part of energy source as free sugar and part as amilaceous material presented the best result. As the Streptomyces sp. Ar386 produced few spores, it was necessary special care to provide sufficient quantity of microorganisms in inoculation. The biosynthesis of antibiotics intensified between the forth and seventh day. The yields varied from 8 to 443 mg of antibiotic complex per litre of medium. As a polyether antibiotic it may be used as anticoccidal agent in poultry and as growth promoters in cattle and swine.

An actinomycete strain (Ar386) was isolated from the soil of the Araraquara regio, SP, Brazil. The strain, named Streptomyces jacareensis, formed irregular rayed, rugose, grayish-white mycelium with sinuous, branched hyphae carrying rare isolated spores; assimilated glucose, galactose, inositol, ribose, maltose, sucrose, melibiose and starch but not mannitol, rhamnose, arabinose, xylose, lactose and raffinose; and contained LL- diaminopimelic acid in its cell wall. An antibiotic active against Gram- positive bacteria, which was characterized as being 26-deoxylaidlomycin and which may have application against poultry coccidiosis, was isolated from cultures of the strain. This was the first isolation of this antibiotic from a microorganism of the genus Streptomyces and also the first isolation of this antibiotic in Brazil.

Fluvial morphometry is method of great value regarding neotectonic analysis of extensive areas because streams, besides representing one of the main agents in the relief modeling, quickly adjust their thalwegs to even the most gentle crustal deformations. The purpose of this paper is to present the application of some morphometric techniques in the Santo Anastácio River hydrographic basin in order to identify recent tectonic deformations. Additionally, we show liquefaction structures identified in the basin and interpreted here as seismites linked to ancient earthquakes (magnitudes greater than 5). The morphometric survey includes longitudinal stream profile analysis, RDE (declivity versus stream length) index application, and the sinuosity study of the Santo Anastácio River channel. Geologic substrate comprises Cretaceous siliciclastic rocks of the Caiuá and Bauru groups, locally covered by Cenozoic sediments (alluvial plains, terrace deposits, colluvial aprons, as well as in situ regoliths). Considering that liquefaction structures affect dark clay layers of 32.340±320 year BP age (14C dating), a lower age limit for the ancient earthquake is triggered in that region. The authors believe that neotectonic understanding of the Western São Paulo State Plateau is important to the geologic and geomorphologic evolution of that landscape and to the consequent territorial planning and occupation.
