We report the degradation of quorum sensing N-acylhomoserine lactone molecules by a bacterium isolated from a Malaysian marine water sample. MALDI-TOF and phylogenetic analysis indicated this isolate BM1 clustered closely to Labrenzia sp. The quorum quenching activity of this isolate was confirmed by using a series of bioassays and rapid resolution liquid chromatography analysis. Labrenzia sp. ...

Lysinibacillus fusiformis strain M5 is a potential hypoxanthine producer that was isolated from clay soil. Here, we present the draft genome sequence that was annotated in order to facilitate future studies of L. fusiformis M5.

We report here the main characteristics of 'Lysinibacillus saudimassiliensis' strain 13S34_airτ (CSUR = P1222), a new species of the Lysinibacillus genus that was isolated from air samples in the city environment of Makkah, Saudi Arabia, during the pilgrim period of Hajj 2012.

A heterotrophic bacterium, isolated from an acidic stream in a disused pyrite mine which contained copious growths of "acid streamers," displayed characteristics which differentiated it from previously described mesophilic acidophiles. The isolate was obligately acidophilic, with a pH range of 2.0 to 4.4 and an optimum pH of 3.0. The bacterium was unable to fix carbon dioxide but oxidized ferro...

A thermophilic protease-secreting bacterial isolate, TPNK-3, from Kiteezi landfill, is an aerobic Gram-positive spore-forming bacterium with rod-shaped cells (3.28 μm long and 0.45 μm wide). Optimal growth was observed at 55°C and pH of 7.0, and the isolate tolerates up to 5% (w/v) NaCl, exhibits extracellular amylolytic, cellulolytic and caseinolytic activities, utilizes a range of carbon and ...

Aminur Rahman (2016): Bioremediation of Toxic Metals for Protecting Human Health and the Ecosystem. Örebro Studies in Life Science 15. Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like canc...

Objective(s):  Biosynthesis of gold nanoparticles (NGPs) is environmentally safer than chemical and physical procedures. This method requires no use of toxic solvents and synthesis of dangerous products and is environmentally safe. In this study, we report the biosynthesis of NGPs using Streptomyces djakartensis isolate B-5.   Materials and Methods: NGPs were biosynthesized by reducing aqueous ...
