The spores of several Bacillus species, including Bacillus pumilus SAFR-032 and B. safensis FO-36b, which were isolated from the spacecraft assembly facility at NASA's Jet Propulsion Laboratory, are unusually resistant to UV radiation and hydrogen peroxide. In order to identify candidate genes that might be associated with these resistances, the whole genome of B. pumilus SAFR-032, and the draf...

Studies on the Optimization of Lipase Production by Rhizopus sp. ZAC3 Isolated from Contaminated Soil a Palm Oil Processing ShedZainab Adenike Ayinla, Adedeji Nelson Ademakinwa, Femi Kayode Agboola

In the present study, rarely explored spore former (Bacillus safensis & Bacillus pumilus) and non-spore (Arthrobacter luteolus, Chryseomicrobium imtechense Corynebacterium efficiens) alkaliphilic calcifying microbes were evaluated for their prolonged survival in cementitious environment. Extensive experimental program was designed to examine mechanical, self-healing, microstructural modificatio...

Petroleum crude oil (PCO)-dwelling microorganisms have exceptional biological capabilities to tolerate the toxicity of petroleum contaminants and are therefore promising emulsifier and/or degraders of PCO. This study describes a set of PCO-inhabiting bacterial species, one of which, identified as Bacillus safensis PHA3, produces an efficient biosurfactant which was characterized as a glycolipid...

Heterodera glycines, the soybean cyst nematode, is the most economically important plant-parasitic nematode on soybean production in the U.S. The objectives of this study were to evaluate the potential of plant growth-promoting rhizobacteria (PGPR) strains for mortality of H. glycines J2 in vitro and for reducing nematode population density on soybean in greenhouse, microplot, and field trials....

Increase of plastics accumulation in the environment cause ecological threats and has been one serious issue worldwide. In current study, two bacterial isolated strains Bacillus safensis amyloliquefaciens were used for their plastic degradation capabilities. The biodegradation low density polyethylene thermoplastic was assessed by weight reduction, Scanning electron microscopy (SEM) analysis cu...

The differentiation between living and dead bacterial endospores is crucial in many research areas of microbiology. The identification of inactivated, non-pathogenic Bacillus anthracis spores is one reason why improvement of decontamination protocols is so desirable. Another field interested in spore viability is planetary protection, a sub-discipline of astrobiology that estimates the bioburde...
