Description
  • Inkubační experimenty s přírodním a umělým subtrátem byly prováděny po dobu 6 měsíců s cílem zjistit rozdíly mezi mikrobiálním biofilmem v povrchovém toku a v hyporheikcých sedimentech. Chlorofyl A, TOC a přímé počty bakterií byly zvoleny jako prametry indikující vývoj bioiflmu. Výsledky naznačují, že navzdory absenci světla mohou řasy být významnou součástí bioiflmů hyporheické zóny, ačkoliv jejich biomasa vyjádřená jako chlorofyl a byla ve srovnání s biofilmem z povrchového toku signifikantně nižší. Domiantní skupinou řas v obou studovaných protředích byly rozsivky. (cs)
  • In order to distinguish between attached microbial communities in a stream and in a hyporheic sediment, incubation experiments with natural and artificial substrates were conducted for 6 months in a small lowland stream. Chlorophyll a, total organic carbon and direct bacterial counts were chosen as parameters indicating the development of biofilms. Results suggest that in spite of the absence of light, live algae may be a significant part of biofilms in hyporheic sediments, although their biomass expressed as chlorophyll a was significantly lower than in biofilms from the surface stream. Diatoms were the dominant group of algae in both environments studied.
