effects of different level administration of bacillus subtilis and bacillus licheniformis on growth performance and survival rate of artemia urmiana
the probiotic effects of two gram positive bacteria, bacillus subtilis and bacillus licheniformis, were examined on growth performance, body composition and survival rate of artemia urmiana. three diets containing 102 (t1), 104 (t2), 106 (t3) cfu of probiotics g feed-1 and a control diet (c) without probiotic were used through a completely randomized design (each with three replicates). the use...
متن کاملEnzyme activities and antibiotic susceptibility of colonial variants of Bacillus subtilis and Bacillus licheniformis.
A nonmucoid colonial variant of a mucoid Bacillus subtilis strain produced less amylase activity and a transparent colonial variant of a B. licheniformis strain produced less protease activity compared with their parents. Antibiotic susceptibility patterns of the colonial variants differed, and increased resistance to beta-lactam antibiotics was correlated with increased production of extracell...
متن کاملAntagonistic Action of Bacillus subtilis Strain SG6 on Fusarium graminearum
Fusarium graminearum causes Fusarium head blight (FHB), a devastating disease that leads to extensive yield and quality loss of wheat and barley. Bacteria isolated from wheat kernels and plant anthers were screened for antagonistic activity against F. graminearum. Based on its in vitro effectiveness, strain SG6 was selected for characterization and identified as Bacillus subtilis. B. subtilis S...
متن کاملIsolation and characterization of cell wall-defective variants of Bacillus subtilis and Bacillus licheniformis.
Quantitative mass conversion of intact bacterial cells of Bacillus subtilis and B. licheniformis to L-phase variants has been effected after lysozyme treatment. After subculture of the unstable L-phase variants for several months in the presence of methicillin, stable L-phase variants were obtained which grew in the absence of the antibiotic and were then unable to revert to the classical bacte...
متن کاملevaluating the effects of bacillus subtilis and corynebacterium glutamicum on soil microbial indexes in different levels of salinity
soil salinity induces a stressful environment for soil micro-organisms and reduces their number and activity. the objective of this research is investigating the effect of different levels of salinity on some of soil biological indicators and also assessing the effect of two types of halotolerant rhizospheric bacteria on the value of these indexes in soil. 35 strains were isolated from saline r...
