Isolation of obligately alkaliphilic magnetotactic bacteria from extremely alkaline environments.
Large numbers of magnetotactic bacteria were discovered in mud and water samples collected from a number of highly alkaline aquatic environments with pH values of ≈ 9.5. These bacteria were helical in morphology and biomineralized chains of bullet-shaped crystals of magnetite and were present in all the highly alkaline sites sampled. Three strains from different sites were isolated and cultured...
متن کاملAmino Acid Substitutions in Cold-Adapted Proteins from Halorubrum lacusprofundi, an Extremely Halophilic Microbe from Antarctica
The halophilic Archaeon Halorubrum lacusprofundi, isolated from the perennially cold and hypersaline Deep Lake in Antarctica, was recently sequenced and compared to 12 Haloarchaea from temperate climates by comparative genomics. Amino acid substitutions for 604 H. lacusprofundi proteins belonging to conserved haloarchaeal orthologous groups (cHOGs) were determined and found to occur at 7.85% of...
متن کاملPreliminary Isolation and Characterization of Halotolerant and Halophilic Bacteria from Salt Mines of Karak, Pakistan
Halophiles are extremophile organisms that thrive in environments with very high concentrations of salt. The salt mines of Karak region, is an extremely saline environment and its microbial communities have not yet been explored. In the present study, twenty one halotolerant and halophilic bacterial strains were isolated from salt mines of Karak region. These strains can grow in media with 5-40...
متن کاملSurvival of gram positive anaerobic cocci on swabs and their isolation from the mouth and vagina.
The survival of Gram positive anaerobic cocci on plain cotton wool and albumin coated swabs held in various transport media was investigated. Results suggested that in most cases Amies', Stuart's and VMGII media do not offer any more protection to the bacteria than storing swabs dry in their containers. A technique was developed for the isolation and identification of Gram positive anaerobic co...
متن کاملIsolation and characterization of two novel halotolerant Catechol 2, 3-dioxygenases from a halophilic bacterial consortium
Study of enzymes in halophiles will help to understand the mechanism of aromatic hydrocarbons degradation in saline environment. In this study, two novel catechol 2,3-dioxygenases (C23O1 and C23O2) were cloned and overexpressed from a halophilic bacterial consortium enriched from an oil-contaminated saline soil. Phylogenetic analysis indicated that the novel C23Os and their relatives formed a n...
