Antimicrobial activity of bioactive compound(s) produced by Bacillus species
Antibiotics are metabolic by-products of complex biosynthetic pathways in microorganisms. They are usually produced by aerobic spore-forming bacteria in the genera Bacillus and Streptomyces and in the Fungi Penicillium and Cephalosporium. Antimicrobials such as bacteriocins are inhibitory peptides or proteins, which have bactericidal effects on micro-organisms closely related to the producer. T...
متن کاملS-layers: principles and applications
Monomolecular arrays of protein or glycoprotein subunits forming surface layers (S-layers) are one of the most commonly observed prokaryotic cell envelope components. S-layers are generally the most abundantly expressed proteins, have been observed in species of nearly every taxonomical group of walled bacteria, and represent an almost universal feature of archaeal envelopes. The isoporous latt...
متن کاملThermophilic 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 کاملChemical composition of the essential oil of two Iranian Satureja species (S. edmondi and S. isophylla)
Satureja genus presents 12 aromatic species in Iran, eight of which are endemic. Because of the several usages of Satureja species or their oils in different industries, we were interested to study the oil content and composition of Iranian Satureja species. In this research, the essential oil content and composition of two endemic species (S. edmondi and S. isophylla) were investigated. Essent...
متن کاملClinical Significance of Bacillus Species Other than Bacillus anthracis
Gram positive aerobic or facultatively anaerobic spore forming gram positive bacilli were first identified by Christian Gottfried Ehrenberg in 1885 and were later classified by Ferdinand Cohn in to a separate genus Bacillus [1]. Aerobic spore forming gram positive bacteria are commonly referred to as ASB’s and includes members of Bacillus spp which are basically saprophytes living as thermophil...
