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...

Objective: To examine the prevalence of mental health disorder and its related factors among Thai nurses. Material and Method: This was cross-sectional descriptive study of 390 female nurses. They were asked to complete the questionnaire which covered personal history, working conditions, job stress and general health. Multiple logistic regression was used to estimate the odds ratio (OR) for me...

The planning process of the Indian government has undergone many changes since its launch in 1951. Decentralised local level planning is currently accepted as the national planning strat egy. Towards this end, the Constitution (73 rd and 74 th Amendments, 1992 & 1993) has been amended to empower the State Governments to form the Institutions of Local self -Governance (ILG). The mandates of such...

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...
