Thermophilic Bacillus Species
The fatty acid composition of a thermophilic Bacillus sp. was altered by the addition of isobutyrate, isovalerate, a-methylbutyrate, leucine, and isoleucine to the growth medium. With isobutyrate, 81% of the fatty acids had 16 carbon atoms and 79% were iso-fatty acids with an even number of carbon atoms. With leucine, 58% of the fatty acids had 15 carbon atoms and 86% were iso-fatty acids with ...
متن کاملProduction of a thermostable extracellular amylase from thermophilic Bacillus species
Isolation and identification of thermophilic Bacillus sp was carried out from a soil sample. The cells were cultivated in a medium containing soluble starch as sole carbon source. The addition of calcium (10 mM) or peptone (1%) and yeast extract (0.5%) to the medium shortened the lag period and improved the growth and amylase synthesis. The optimum temperature for amylase production was detecte...
متن کاملOccurrence of isocitrate lyase in a thermophilic bacillus species.
A thermophilic, sporeforming bacterium has been isolated from soil on a medium containing acetate as a carbon source. This organism is similar to Bacillus stearothermophilus in most respects but differs in its inability to hydrolyze starch. Isocitrate lyase is present in cell-free extracts of organisms grown in a medium with acetate as a carbon source. The specific activity was 400 times lower ...
متن کاملProduction of a Thermostable Extracellular Protease from Thermophilic Bacillus Species
Isolation and identification of thermophilic Bacillus sp was carried out from soil samples of a tannery area. The isolate KCPSS-3, when cultivated in liquid cultures containing trisodium citrate, produced protease. The production reached a maximum in 9 h, with levels of 2.15 U/mg protein. The microorganism utilized several carbon sources for the production of protease. Starch was found to be th...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
