Heterotrophic fixation of CO2 in soil
Original language description
The occurrence of heterotrophic CO2 fixation by soil microorganisms was tested in several mineral soils differing in pH and two artificial soils (a mixture of silica sand, alfalfa powder, and nutrient medium inoculated with a soil suspension). Soils wereincubated at ambient (~0,05 vol%) and elevated (~5 vol%) CO2 concentrations under aerobic conditions for up to 21 days. CO2 fixation was detected using either a technique for determining the natural abundance of 13C or by measuring the distribution of labeled 14C-CO2 in soil and bacteria. The effects of elevated CO2 on microbial biomass (direct counts, chloroform fumigation extraction method), composition of microbial community (phospholipid fatty acids), microbial activity (respiration, dehydrogenaseactivity), and turnover rate were also measured. Heterotrophic CO2 fixation was proven in all soils under study, being higher in neutral soils. The main portion of the fixed CO2 (98-99%) was found in extracellular metabolites.

Heterotrofní fixace CO2 v půdě
Czech description
Prokázali jsme, že heterotrofní mikroorganismy v půdě mohou využívat uhlík z oxidu uhličitého. Fixovaný oxid uhličitý je zabudováván především do extracelulárních metabolitů (98%) a jen malá část je zabudovávána do buněčných struktur (1-2%).
