In order to expand the range of dairy products for elderly, a technology has been developed preparing fermented milk drink with stevia, using combined starter culture from kefir fungi, bulgarian bacillus, thermophilic streptococcus and bifidobacteria. During research, modern standard methods were used. The research was carried out in laboratory Research Institute Agroecology Gorsk State Agraria...

Enzymes, and particularly proteases, have become an important and indispensable part of industrial processes such as laundry detergents, pharmaceuticals and food products. Detergents such as Tide, Ariel and Biz contain proteolytic enzymes, most of them produced by members of the genus Bacillus. This paper describes the compatibility of protease produced by the thermophilic Bacillus sp, with com...

anaerobic digestion of organic solid waste (osw) from kitchen was conducted in completely stirred tank reactors (cstrs) under both mesophilic and thermophilic conditions. the lab-scale reactors were fed with the osw containing 10% of total solids (ts) at a hydraulic retention time (hrt) of 30 days (3.0-3.5 g-ts/l/d of volumetric loading rate). both mesophilic and thermophilic reactors exhibited...

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 aci...

The phylogenetic diversity of the bacteria in hot composting samples collected from three spatial locations was investigated by molecular tools in order to determine the influence of gradient effect on bacterial communities during the thermophilic phase of composting swine manure with rice straw. Total microbial DNA was extracted and bacterial near full-length 16S rRNA genes were subsequently a...

Thermostability is a characteristic of most of the enzymes available for bulk industrial usage. Thermophilic microorganisms are of special interest as a source of novel thermostable enzymes. A total of 50 bacterial strains, isolated from local hot springs and ash samples were screened for the extracellular enzyme production including amylase, lipase, esterase, cellulase and β-galactosidase. As ...
