Approximately 3% of the deoxyribonucleic acid (DNA) of Bacillus pumilus NRS576 can be isolated as covalently closed, circular duplex molecules of homogeneous size. The mol wt of the 576 plasmid is approximately 30 million. NRS576 (plasmid(+)) is oligosporogenic; less than 1% of the cells form spores during incubation in liquid AK sporulation medium. Variants that form spores at a high frequency...

Saffron (Crocus sativus) is a medicinally important plant. The Kashmir valley (J&K, India) emblematizes one of the major and quality saffron producing areas in the world. Nonetheless, the area has been experiencing a declining trend in the production of saffron during the last decade. Poor disease management is one of the major reasons for declining saffron production in the area. Endophytes ar...

Biomaterials must be both sterile and free of contaminants prior to use, and this is particularly critical for the next generation of implants based on tissue engineering. With increasing complexity of tissue engineering scaffolds and multifunctional devices, there is a need for new approaches to decontamination, i.e. cleaning, disinfection, and sterilization. This work presents our recent resu...

An extracellular keratinase from Bacillus pumilus KS12 was purified by DEAE ion exchange chromatography. It was a 45 kDa monomer as determined by SDS PAGE analysis. It was found to be an alkaline, serine protease with pH and temperature optima of 10 and 60°C, respectively. It was thiol activated with two- and eight-fold enhancement in presence of 10 mM DTT and β-mercaptoethanol, respectively. I...

The growth of plants promoting rhizobacteria (PGPR) that live actively in plant roots and rhizosphere support has gained widespread importance agriculture. This study was carried out to obtain identify PGPR isolates from wheat soil determine their ability capacity on yield. So, were obtained soil, they identified as Bacillus sp. (B. simplex B. pumilus) by biochemical tests MALDI-TOF MS. After t...
