Effect of sodium hypochlorite on the microbiota and odor of manure effluents

Manure effluents (ME) of livestock enterprises represent a rich nutrient medium for the development various aerobic microorganisms (MO). During biodegradation organic components ME, wide range odor-forming substances (OFS) and greenhouse gases enter atmospheric air. The intensity main directions ME destruction depend on composition amount microbiota. A solution sodium hypochlorite can be used to suppress decomposition biogenic ME. In course our research, it was found that introduction 0.005% active chlorine into liquid fraction (pH ~ 6.8; humidity 99.1%) leads decrease in numbers putrefactive microbiota, namely: Bacteroides, Clostridium, Escherichia coli, Pseudomonas, Sarcina ventriculi, Peptostreptococcus anaerobius. corresponding ammonifiers are actively involved processes form acetic acid, isovaleric butyric indoles, skatoles, ammonia, hydrogen sulfide, mercaptans others. microbiota not making significant contribution production OFS (Saccharomyces cerevisiae, Rhodotorula glutinis, Lactobacillus ssp. others), contrary, increased. some producers volatile fatty acids (VFA), Anaerococcus prevotii, Acidaminococcus, Prevotella spp. etc. However, this did affect nature odor, which explained by formation non-volatile VFA salts at pH above 7.0. Staphylococcus aureus, epidermidis, Klebsiella sp., Proteus ssp., Alistipes putredinis, Bifidobacterium Candida tropicalis, albicans almost change when NaOCl added As result transformation, total emission gaseous substances, whose CO2 CH4, decreased more than 17%. unpleasant odor has significantly decreased. treat manure storage baths. practice treating with biocide is facilitated its availability, low cost safety environment.
