摘要: Abstract Succession of communities different bacteria and fungi, mainly proteolytic keratinolytic ones, was observed during composting chicken feathers with pine bark (FB) bark/rye straw (FBS). The succession dominated by fungal than bacterial communities. Bacteria, including Actinomycetes , grew intensively the first 2–4 weeks included proteolytic, rarely cellulolytic, populations; afterwards, were gradually replaced fungi. Meso- thermophilic ubiquitous cellulolytic appeared among representatives as first, while strains detected in compost biomass at 6th week process. development within second group significantly more intensive that populations. intensity growth particular ecological–physiological found to be dependent on chemical content C/N ratio strongest C/N = 25 composts.
