throughout the present study, some bacillus spp. were isolated from soil, and the effectiveness of the medicinal plant cuminum cyminum l.’s essential oil extracts were tested against the isolated bacteria. the bacillus spp.were identified through 16s rdna sequence analysis and the antibacterial activity of various organic solvent extracts as well as the essential oils of c. cyminum l. determine...

The aim of this study was to evaluate the effects incorporating Bacillus spp.-fermented mixture (FM; 55% soybean meal and 45% feather meal) in starter feed goat kids, specifically its on growth performance, blood profile, carcass characteristics, gastrointestinal traits; FM protein profile also evaluated. Seventy-five four-week-old male dairy kids were randomly assigned three different diet gro...

Heat shock of Bacillus subfi/is CU1147, a strain lysogenic for SPpc2, a prophage with a thermosensitive repressor, results in phage induction and subsequent cell lysis. Cloning in Escherichia coli and sequencing of a DNA fragment of prophage SPp led to the identification of blyA, the gene encoding a 367 amino acid polypetide with a molecular mass of 39.6 kDa. Purified BlyA obtained from the E. ...

Two questions have arisen concerning the article of Smuckler and Appleman (Appl. Microbiol. 12:355, 1964). The question of the development of toxicity in sodium azide media had been studied in our laboratory, but these data were omitted from the publication as it was not necessarily relevant to the reported results. Gerencsen and Weaver (Appl. Microbiol. 7:113, 1959) reported that sodium azide ...

The present study explored the efficacy of Bacillus spp. and protease production for biocontrol of the root-knot nematode Meloidogyne javanica in African violet media. Among 100 bacterial isolates from various soils, the highest nematode mortality was observed for treatments with isolate GM-18, which was identified as Bacillus subtilis based on cultural and morphological characteristics and 16S...

BACKGROUND: Applications of bacteriocins as food preservatives have been so far limited, principally because of their low antimicrobial activity in foods. Nisin is the only bacteriocin of significant use, but applications are restricted principally because of its very low activity at neutral or alkaline pH. Thus the isolation of new bacteriocins active in foods is desirable. RESULTS: We isolate...

conclusions this study indicated that some bacillus species have the potential to produce antimicrobial compounds which can be used to control microbial infections. results the identified bacillus species included b. cereus (86.6%), b. subtilis (6.6%), b. thuringiensis (3.3%), and b. pumilus (3.3%). evaluation of the antimicrobial activity of the extracted compounds was carried out against five...

Clonal eucalyptus plantings have increased in recent years; however, some clones with high production characteristics have vegetative propagation problems because of weak root and aerial development. Endophytic microorganisms live inside healthy plants without causing any damage to their hosts and can be beneficial, acting as plant growth promoters. We isolated endophytic bacteria from euc...

Jan‰tová B. , J . Luká‰ová: Heat Resistance of Bacillus spp. Spores Isolated from Cow’s Milk and Farm Environment. Acta Vet. Brno 2001, 70: 179-184. The aim of this study was to compare heat resistance of the spores of mesophile Bacillus spp. from raw milk (bulk tank milk and milk from individual cows) and farm environment (faeces, silage, litter, swabs from skin and udder) as related to their ...
