the objective of this study was to isolate halophilic bacteria with the ability to produce intracellular or extracellular l-asparaginase. a total number of 120 halophilic bacteria were isolated from 17 different saline habitats of iran including salt lakes, wetlands, brine springs and deserts. among these, 68 were able to grow in the presence of 1.5 m nacl and 52 demonstrated the ability to gro...
The temporal stability and diversity of bacterial species composition as well as the antilisterial potential of two different, complex, and undefined microbial consortia from red-smear soft cheeses were investigated. Samples were collected twice, at 6-month intervals, from each of two food producers, and a total of 400 bacterial isolates were identified by Fourier-transform infrared spectroscop...
Article history: Received on: 11/04/2016 Revised on: 09/05/2016 Accepted on: 24/06/2016 Available online: 29/10/2016 Drug resistance in microorganisms is an emerging phenomenon that poses challenges to public health and treatment. The reservoir of drug resistance genes found in the resistome of environmental isolates in aquatic saline systems has been augmenting continuously. The spread of drug...
During the course of studies on halophilic, Gram-negative bacteria, a comparison of two strains of halophilic bacteria, Pseudomonas halophila DSM 3050 and Halomonas variabilis DSM 3051 (formerly Halovibrio variabilis) demonstrated that the characteristics of strain DSM 3050 corresponded to the original description of Halovibrio variabilis and those of DSM 3051 to P. halophila, both of which had...
Species of the genus Halomonas are halophilic and their flexible adaption to changes of salinity and temperature brings considerable potential biotechnology applications, such as degradation of organic pollutants and enzyme production. The type strain Halomonas lutea YIM 91125 was isolated from a hypersaline lake in China. The genome of strain YIM 91125 becomes the twelfth species sequenced in ...
Diversity and physiology of polyhydroxyalkanoate-producing and -degrading strains in microbial mats.
Photosynthetic microbial mats are sources of microbial diversity and physiological strategies that reflect the physical and metabolic interactions between their resident species. This study focused on the diversity and activity of polyhydroxyalkanoate-producing and -degrading bacteria and their close partnership with cyanobacteria in an estuarine and a hypersaline microbial mat. The aerobic het...
Halomonas sp. strain MCTG39a was isolated from coastal sea surface water based on its ability to utilize n-hexadecane. During growth in marine medium the strain produces an amphiphilic exopolymeric substance (EPS) amended with glucose, which emulsifies a variety of oil hydrocarbon substrates. Here, we present the genome sequence of this strain, which is 4,979,193 bp with 4,614 genes and an aver...
Halophilic and salt-resistant bacteria were isolated from soil samples collected from Tunisia. Among them, strain 21a grew at NaCl concentration ranging 1-15%, optimum at 3%, showing that it is moderately halophilic bacteria. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain 21a was closely related to Halomonas aquamarina and H. venusta with sequence similarities of 9...
1, 4, 5, 6-tetrahydro-2-methyl-4-pyrimidine carboxylic acid (ectoine) is an excellent osmoprotectant. ectoine and hydroxyl ectoines are of great significance to the biotechnology industry, thus the detection and isolation of ectoine producing bacteria is of great importance. hence, this study involved the detection of the ectc gene (encoding ectoin synthase enzyme) using polymerase chain reacti...
