Impact of a microbial-mineral biopreparation on microbial community and deodorization of manures.
AbstractThe aim of this study was to determine the number of bacteria in poultry, cattle and swine manure in order to perform hygienization and deodorization using a microbial-mineral biopreparation. The highest number of bacteria was recorded in laying hens manure (5.1×10(10) cfu/g). It was noted that bacteria: coliforms, E. coli, Clostridium, Enterococcus number was reduced (1-2 log) after the biopreparation application. The investigated odorous compound concentrations were reduced with 34-78% efficiency, depending on the type of manure and odorant. All odorous compounds were efficiently reduced only in the case of laying hen manure.
