The bacterial composition of permafrost samples taken during drilling frozen marine sediments in the area Barentsburg coal mine on east coast Grønfjord Bay Western Spitsbergen has been studied. study was based analysis V4 region 16S rRNA gene, carried out using next generation sequencing, as well classical microbiological methods (direct luminescence microscopy and aerobic cultivation).The tota...

In this study, microbiological quality of drinking water deriving from the private wells Koprivnica-Križevci County was investigated. A total 287 samples different locations were collected during 2018 and analysed for following parameters: coliforms, Escherichia coli, Enterococcus spp., Clostridium perfringens, Pseudomonas aeruginosa, number aerobic heterotrophic bacteria at 36 °C 22 °C. The re...

The aim of this project was to assess the diversity of iron metabolizing bacteria in several ecological niches by culture-dependent and culture-independent methods. In particular, we wanted to determine whether non-phototrophic, anaerobic nitrate-dependent Fe(II)-oxidizers coexist with aerobic Fe(1I)-oxidizers and facultatively anaerobic Fe(III)-reducers in natural habitats. To this end, we sam...

Studies were carried out on the microflora of phyllosphere and soil rhizosphere of hulled (Chwat variety) and naked (Akt variety) oats. The material taken for study embraced samples of leaves and soil rhizosphere taken from cultivations differing in extent of nitrogen fertilization. The studies involved determination of total number of aerobic heterotrophic bacteria belonging to the genus Pseud...

BACKGROUND This study investigated the interaction between heterotrophic bacteria and coliform, fecal coliforms, fecal streptococci bacteria in water supply networks. METHODS This study was conducted during 2013 on water supply distribution network in Aq Qala City, Golestan Province, Northern Iran and standard methods were applied for microbiological analysis. The surface method was applied t...

The saline springs of Gypsum Hill in the Canadian high Arctic are a rare example of cold springs originating from deep groundwater and rising to the surface through thick permafrost. The heterotrophic bacteria and autotrophic sulfur-oxidizing bacteria (up to 40% of the total microbial community) isolated from the spring waters and sediments were classified into four phyla (Actinobacteria, Bacte...

Rivers around the world are threatened by destruction caused anthropogenic activities despite important services they provide for humanity. This study was conducted to determine water classification and recommended beneficial uses of Palhi Salog based on most probable numbers total coliforms, also evaluate abundance heterotrophic bacteria present in sediments rivers as potential indicators envi...
