畜禽粪臭素的产生、代谢及其体外降解研究进展
Advances in Production and in vitro Degradation of Skatole in Livestock and Poultry
摘要
Abstract
In recent years,the development of intensive animal husbandry has led to odor pollution caused by livestock breeding,which has become a significant bottleneck problem hindering the green and sustainable development of animal industry.Skatole is an indole substance produced from tryptophan through anaerobic microorganisms in the posterior intestine.It has a low olfactory threshold concentration and emits a strong fecal odor,making it one of the primary odor compounds released from livestock and poultry feces.Research indicated that skatole production exhibited temporal-spatial effects and was closely associated with intestinal microbial composition.Skatole not only negatively impacts the health of livestock and poultry but also affects meat quality,posing potential threats to human health.Non-biological degradation methods such as photocatalytic degradation,ozonation,and the Fenton reaction have demonstrated certain efficiency in vitro.However,their application scope is limited compared to microbial degradation due to environmental concerns and lower efficacy rates.Currently,various strains capable of degrading skatole have been screened including Pseudomonas,Rhodococcus,Acinetobacter,etc.,which convert skatole into less toxic or non-toxic substances through different biochemical pathways.Nevertheless,the complete understanding of microbial degradation mechanisms for skatole remains elusive while practical applications still encounter challenges.Future research should focus on screening more efficient skatole-degrading strains along with analyzing the mechanism employed by degrading microorganisms.Furthermore,studying the types of gut microbiota responsible for producing skatole,as well as their influencing factors,will contribute to the promotion of environmentally friendly practices within the livestock and poultry industry.关键词
