1. Hydrolysis of insoluble fish protein residue from whitemouth croaker (Micropogonias furnieri) by fungi
A significant amount of insoluble fibrous protein, in the form of feather, hair, scales, skin and others are available as co-products of agro industrial processing. These wastes are rich in keratin and collagen. This study evaluated different fungi for the hydrolysis of insoluble fish protein residues. Proteins resulting from Micropogonias furnieri wastes th

2. Influência do Gene pacC na Regulação de Manosiltransferases no Dermatófito Trichophyton rubrum em Função de Variações Nutricionais e pH Ambiente. / Influence of Gene pacC in Mannosiltransferase Regulation of the Dermathophyte Trichophyton rubrum in Function to Changes by pH and Nutrient Sources.
Gene expression regulation is essential for fungi to adapt to environmental adversities, such as changes in the extracellular pH, nutrient starvation, ionic strength, and temperature. The adaptive response to ambient pH is well characterized in model fungi such as Aspergillus nidulans, and involves the signal transduction pathway consisting of the products o

3. Feather degradation by strains of Bacillus isolated from decomposing feathers
Feather waste is generated in large amounts as a by-product of commercial poultry processing. This residue is almost pure keratin, which is not easily degradable by common proteolytic enzymes. Eight strains of Bacillus, isolated from decomposing feathers were tested for the hydrolysis of feather wastes in the laboratory. Among these strains, Bacillus cereus

4. Caracterização e aplicação de proteases produzidas por linhagens de Bacillus sp. / Production, characterization and application of proteases produced by strains of Bacillus sp
Algumas enzimas são encontradas facilmente em diferentes microrganismos do ambiente e requerem um destaque especial devido a seu grande valor econômico. As proteases apresentam grande diversidade bioquímica, sendo facilmente manipuláveis, favorecendo dessa maneira suas aplicações biotecnológicas. Três linhagens bacterianas de Bacillus sp. foram isola

5. Purification and Characterization of a Keratinase from a Feather-Degrading Bacillus licheniformis Strain
A keratinase was isolated from the culture medium of feather-degrading Bacillus licheniformis PWD-1 by use of an assay of the hydrolysis of azokeratin. Membrane ultrafiltration and carboxymethyl cellulose ion-exchange and Sephadex G-75 gel chromatographies were used to purify the enzyme. The specific activity of the purified keratinase relative to that in th

6. Isolation, Identification, and Characterization of a Feather-Degrading Bacterium †
A feather-degrading culture was enriched with isolates from a poultry waste digestor and adapted to grow with feathers as its primary source of carbon, sulfur, and energy. Subsequently, a feather-hydrolytic, endospore-forming, motile, rod-shaped bacterium was isolated from the feather-degrading culture. The organism was Gram stain variable and catalase posit
