Coexistence of microbial populations and autostabilization of regulating factors in continuous culture: theory and experiments

摘要: The paper summarizes the author’s theoretical and experimental researches aimed at studying rule of stable coexistence interacting microbial populations within same trophic level. Populations yeast algae interact in open continuous cultures through regulating factors (RFs), which come together by ability to be released or taken up a population affect growth this other population. Theoretical studies show that steady state, number coexisting species is not greater than RFs. Two-dimensional regions with different resultant compositions equilibrium communities are plotted coordinates “input levels RFs”. This perhaps first study showing background steady-state RFs system related their input levels. effect has been termed autostabilization RFs, its basis developed. A new criterion intra- inter-population interactions introduced for RFs—growth acceleration response change density. Based on proposed criterion, estimates intensity sign between given, allowing quantification complex relationships, was earlier unattainable. An integrated approach detection based effect.
