This study investigated the effects of salinity increase on bacterial community structure in a membrane bioreactor (MBR) for wastewater treatment. The influent salt loading was increased gradually to simulate salinity build-up in the bioreactor during the operation of a high retention-membrane bioreactor (HR-MBR). Bacterial community diversity and structure were analyzed using 454 pyrosequencin...
Isolation and taxonomic and phylogenetic studies performed in this decade have revealed that most Gram-positive, aerobic spore-forming bacteria which have halophilic/halotolerant/alkaliphilic and/or alkalitolerant properties compose a considerably large phylogenetic group within rRNA 1 group of Ash et al. (1991) in the phyletic assemblage of bacteria classically defined as the genus Bacillus (A...
Na+/H+ exchange activity in whole cells of the halotolerant alga DunaIfeila saUna can be elicited by intracellular acidification due to addition of weak acids at appropriate external pH. The changes in both intracellular pH and Nat were followed. Following a mild intracellular acidification, intracellular Nat content increased dramatically and then decreased. We interpret the phase of Nat influ...
A moderately halotolerant, Gram-positive, aerobic, motile, spore-forming bacterium, designated as strain YAS1, was isolated from an olive-brine fermentation rich in aromatic compounds, after enrichment on tyrosol. Strain YAS1 grew between 25 and 45 degrees C and optimally at 37 degrees C. It grew in the presence of 0-15% (v/w) NaCl, with an optimum of 3-6% (v/w) NaCl. The DNA G+C content was fo...
The principal genomic features of Acidihalobacter prosperus DSM 14174 (strain V6) are presented here. This is a mesophilic, halotolerant, and iron/sulfur-oxidizing acidophile that was isolated from seawater at Vulcano, Italy. It has potential for use in biomining applications in regions where high salinity exists in the source water and ores.
Virgibacillus pantothenticus DSM 26(T) is a Gram-positive, spore-forming, aerobic, mesophilic, and halotolerant bacterium. Here, we report its 4.76-Mb draft genome sequence, which is the first genome information of V. pantothenticus and will promote biological research and biotechnological application for the species.
The highly halotolerant and allopolyploid yeast Zygosaccharomyces rouxii is industrially used for the food production in high concentrations of salt, such as brewing soy sauce and miso paste. Here, we report the draft genome sequence of Z. rouxii NBRC 1876 isolated from miso paste.
BACKGROUND Many workers have reported halotolerant bacteria from saline conditions capable of protease production. However, antibiotic resistance and heavy metal tolerance pattern of such organisms is not documented very well. Similarly, only a few researchers have reported the pattern of pH change of fermentation medium during the course of protease production. In this study, we have isolated ...
The halotolerant alga Dunaliella salina is a model for stress tolerance and is used commercially for production of beta-carotene (=pro-vitamin A). The presented draft genome of the genuine strain CCAP19/18 will allow investigations into metabolic processes involved in regulation of stress responses, including carotenogenesis and adaptations to life in high-salinity environments.
Myxococcus fulvus HW-1 (ATCC BAA-855) is a halotolerant marine myxobacterium. This strain exhibits complex social behaviors in the presence of low concentrations of seawater but adopts an asocial living pattern under oceanic conditions. The whole genome of M. fulvus HW-1 will enable us to further investigate the details of its evolution.
