key dissimilarities between thermophilic and mesophilic anaerobic digestion of waste activated sludge (was) were experimentally studied in this research. typical was with total solids (ts) concentrations of 30 and 60 g/l were digested anaerobically in a batch digester at mesophilic and thermophilic temperatures. solids reduction, total cod changes, the production of different volatile fatty ...

The VAO flavoprotein family consists mostly of oxidoreductases harboring a covalently linked flavin cofactor. The linkage can be either monocovalent at position 8 with a histidine or tyrosine or bicovalent at position 8 with a histidine and at position 6 with a cysteine. Bicovalently bound flavoproteins show a preference for bulkier substrates such as oligosaccharides or secondary metabolites. ...

Abstract Background Biomass-degrading enzymes with improved activity and stability can increase substrate saccharification make biorefineries economically feasible. Filamentous fungi are a rich source of carbohydrate-active (CAZymes) for biomass degradation. The newly isolated LPH172 strain the thermophilic Ascomycete Thielavia terrestris has been shown to possess high xylanase cellulase activi...

A cellulolytic, thermophilic actinomycete (previously isolated from municipal refuse compost samples) was identified as Thermomonospora curvata. A determination was made of the optimal conditions for cellulase production by T. curvata when grown at 55 C in a medium containing mineral salts, cellulose, and yeast extract. The pH and temperature optima (pH 6.0 and 65 C) for the cellulase produced ...

Mesophilic bacteria, fungi and actinomycetes varied during composting cycles with high numbers in the initial and final cycles with maximal values in compost C and D, and sharply decreased in the heating cycles. Staphylococcus aureus and Bacillus subtilis were dominated at the initial composting cycle. Whereas, at maturity Bacillus subtilis was the major followed by B.badi...
