Růstová charakteristika a skladba funkčních skupin půdního mikrobiálního společenstva
Černá, B. ; Elhottová, Dana ; Šantrůčková, Hana
Oxyggen consumption was used for measuring growth parameters of functional microbial groups in two soils of different texture after addition of mineral, sugar-ammonium and complex media. Phospholipid fatty acids analysis (PLFA) was used to determine differences in community composition and structure. Growth parameters and composition based on a complete PLFA pattern of the microbial community, changed as a response to medium addition and type of incubation. The proportion of actinomycetes decreased whereas the proportion of fungi increased after addition both of the sugar-ammonium and complex media. Gram-negative bacteria dominated after addition of the substrates rich carbon source, while Gram-positive bacteria prevailed after addition of the carbon and nitrogen rich medium.
