Research on ecophysiology of benthic bacteria indicates that microbiological processes which occur in bottom sediments have a major influence on the development of water bodies. Organic matter accumulated on the bottom makes lakes shallower and accelerates their aging. Microbiological processes are particularly important in small lakes, which are a common element of the environment. This article presents...
Air sampling by impaction was conducted at eight sampling sites in a seasonal cycle (sites I–IV located in the center of Bydgoszcz, sites V–VIII located in the Fordon district). The results indicate the dominance of mold fungi (77%). Heterotrophic mesophilic bacteria were the second most numerous (22%) while actinomycetes accounted for a small percentage of the total number of microorganisms (1%)...
The research was carried out in Lake Piecki and Lake Nawionek, two lobelia lakes located within the Zaborski Landscape Park. Water samples were collected from the surface and bottom water layers in spring, summer and autumn 2009. The analysis reveals that the total number of planktonic bacteria (TNB) in Lake Nawionek ranged between 8.83 and 36.22·10⁵ cells/cm³ and between 15.77 and 44.93·10⁵ cells/cm³...
W pracy przedstawiono wyniki liczebności bakterii heterotroficznych rozwijających się w temperaturze 22°C i w 37°C oraz bakterii wskaźnikowych stanu higieniczno-sanitarnego (bakterii z grupy coli - TC, bakterii coli termotolerancyjnych - FC, paciorkowców kałowych - FS oraz Clostridium perfringens) występujących w toni wodnej Strugi Jarcewskiej. W wodzie Strugi Jarcewskiej dominowały heterotroficzne...
