The effects of different dilutions of seminal plasma (SP) on the qualitative characteristics of rabbit spermatozoa and on their fertilising ability were analysed. Ejaculated semen was centrifuged twice and the sperm resuspended in media with decreasing ratios of SP/Tris: (1/2; 1/5; 1/10; 1/20; 1/30; 1/100) until the complete substitution was with SP. The control constituted sperm in undiluted S...

Bacillus is a rhizobacterium that can help with the nutrient cycle in soil. Plant growth-promoting rhizobacteria (PGPR) be found rhizosphere of many plants. This research was divided into two parts: (1) test ability genus isolates to withstand various NaCl concentrations saline and acidic soils; (2) quantification secondary metabolites produced by form hormones organic acids. valezensis (BPF2),...

Endophytic fungi isolated from Rauvolfia serpentina, a well known Indian medicinal plant, is used in Ayurveda for treatment of many diseases. Isolated endophytes were screened for their antibacterial activity against pathogenic bacteria. Twenty fungal isolates were recovered from different parts of the host plant and they were characterized for their morphological features through Scanning Elec...

N-4909 (1), which has a stimulating activity on apolipoprotein E secretion in humanhepatoma Hep G2 cells, was isolated from the culture broth of Bacillus sp. No. 4691 by Hiramoto et al.l) This compound (1) was also isolated from Bacillus sp. A1238 as an inhibitor of acyl-CoA; cholesterol acyltransferase by Hasumi et al.2) This cyclooctadepsipeptide (1) and its diastereomer were synthesized for ...

The current study was attempted to isolate and characterize the protease producing Bacillus sp. Among the 3 strains isolated from soil sample collected from kuppam region, Chennai, India. One strain (PR01) exhibited potent proteolytic activity. Based on the morphological, biochemical and molecular characterization, the isolate (PR01) was identified as Bacillus sp. The strain was designated as B...

A heterotrophic nitrifier, named Bacillus sp. LY, was newly isolated from a membrane bioreactor (MBR). Bacillus sp. LY could utilize the organic carbon as the source of assimilation when it grew on glucose and ammonium chloride medium companying the formation of oxidized-nitrogen. It also could denitrify nitrate while nitrification. After 24 days incubation, the removal efficiencies of the COD ...

The performance of isolated designed consortia comprising Bacillus pumilus, Brevibacterium sp, and Pseudomonas aeruginosa for the treatment of sewage wastewater in terms of reduction in COD (chemical oxygen demand), BOD (biochemical oxygen demand) MLSS (mixed liquor suspended solids), and TSS (total suspended solids) was studied. Different parameters were optimized (inoculum size, agitation, an...

It is important to use renewable resources to maximize crop yields and minimize the environmental hazards associated with chemical residues. Composting is an age old practice for the biological conversion of organic waste to a humus-like substance which can enhance physical, chemical and biological soil properties. To explore the effect of microorganisms in the composting process, three potent ...
