Several products of industrial interest are produced by Bacillus, including enzymes, antibiotics, amino acids, insecticides, biosurfactants and bacteriocins. This study aimed to investigate the potential of two bacterial isolates (P5 and C3) from puba, a regional fermentation product from cassava, to produce multiple substances with antimicrobial and surface active properties. Phylogenetic anal...

Lantibiotics are bacteriocins that contain unusual amino acids such as lanthionines and alpha, beta-didehydro residues generated by posttranslational modification of a ribosomally synthesized precursor protein. The structural gene encoding the novel lantibiotic epilancin K7 from Staphylococcus epidermidis K7 was cloned and its nucleotide sequence was determined. The gene, which was named elkA, ...

in this survey, the effect of two commercial products trichodermin (trichoderma harzianum bi ) and subtilin (bacillus subtilis s) along with one strain of t. virens vm1 isolated from sugar beet farms of mashhad were used for controlling heterodera schachtii in field conditions. t. virens vm1 was formulated as two other commercial products. in this order, this strain was sub cultured on p.d.a. t...

38, 6th ASM Conference on Streptococcal Genetics, Ashville, NC, USA]. GBS β-h/c contributes to virulence in animal studies. When administered to neonatal rats via the pulmonary route, NH GBS mutants possess a 1000-fold greater LD50 than the wild-type parent strains, confirming a role in the pathogenesis of pneumonia and systemic spread [52]. In an adult mouse model of GBS arthritis, hemolysin e...

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...

22 The lantibiotic lacticin 3147 has been the focus of much research due to its broad spectrum of 23 activity against many microbial targets, including drug resistant pathogens. In order to protect 24 itself, a lacticin 3147 producer must possess a cognate immunity mechanism. Lacticin 3147 25 immunity is provided by an ABC transporter, LtnFE, and a dedicated immunity protein, LtnI, 26 both of w...
