Background: Infections are readily transmitted as a result of bacterial contamination of swimming pools. Therefore, hygiene and preventing the contamination of swimming pools is of particular importance. The objective of this study was to determine the amount of bacterial contamination in indoor pools of Yazd in 2013. Methods: In this descriptive and analytical study, all indoor swimming pools ...

Autothermal thermophilic aerobic digestion (ATAD) is used to treat human excreta hygienically. We previously reported a unique full-scale ATAD, showing distinctive bacterial community transitions and producing high-nitrogen-content liquid fertilizer; nevertheless, the mechanism remains unclear. One hypothesis involves using gas-inducing (GI) agitator. designed lab-scale GI system compared it wi...

Fifty different polyhydroxyalkanoic acid (PHA)-accumulating bacterial strains were investigated for the occurrence of phasin proteins bound to PHA granules and related to the GA24 protein of Alcaligenes eutrophus H16, by isolating PHA granules and Western blot analysis of granule-associated proteins employing antibodies raised against the GA24 protein. It could be demonstrated that th PHA granu...

This paper presents the influence of penicillin, erythromycin, oxytetracycline and streptomycin on aquatic microorganisms isolated from three reservoirs with varied extent of environmental pollution (Sulej6w Reservoir, Zegrze Reservoir and Vistula River). The experiments were conducted in especially prepared microcosms (aerated 151 aquariums). From among the examined antibiotics streptomycin sh...

During 1997-2005, the microbiological quality and susceptibility of bacterial isolates of swimming pool waters were investigated. A total of 462 water samples were collected from three indoor swimming pools (a teaching pool, a competition public pool, a hydrotherapy pool) and two outdoor swimming pools (a hotel semi-public and a residential private pool) in Northwestern Greece. All water sample...

The gene encoding a denitrification enzyme, nitrous oxide reductase (EC 1.7.99.6), in Rhizobium meliloti and other gram-negative bacteria was detected by hybridization to an internal 1.2-kb PstI fragment of the structural gene (nosZ) cloned from Pseudomonas stutzeri Zobell (W.G. Zumft, A. Viebrock-Sambale, and C. Braun, Eur. J. Biochem. 192:591-599, 1990). Homology to the probe was detected in ...

A multitude of roles is played by microbes in food and agriculture that include nutrient cycling management, organic matter decomposition fermentation. Plant growth promoting rhizobacteria (PGPR), representing microbial groups with ability colonizing plant roots, influence through various indirect direct modes order to promote its and/or protect it from diseases or damage due insect attack.
