摘要
为探究畜牧业生产活动肉鸡屠宰加工对空气环境的影响,试验从某大型肉鸡屠宰场选取了3类不同的功能区作为采样点,通过分离培养菌种鉴定,运用BIOLOG微生物全自动分析仪,首次对各采样点分离培养的细菌、真菌进行种属鉴定。所分离的培养物中共鉴定出细菌菌属47种,其中革兰氏阳性菌比例远高于革兰氏阴性菌,优势菌属依次为微球菌属、葡萄球菌属、芽孢杆菌属、棒杆菌属和假单胞菌属,其中20%~30%为微球菌属;鉴定出真菌菌属共12属,优势真菌依次为枝孢属、链格孢属、毛霉属、曲霉属和青霉属。该肉鸡屠宰场屠宰活动对空气环境未产生不利影响。随着畜牧业生产活动的快速发展以及屠宰加工厂布局设计规划,畜禽屠宰加工引起的环境污染问题应引起更多的关注。
The aim of the present study was to investigate the impact of animal husbandry production activities such as slaughtering and processing of broilers on the air environment.The experiment selected three different functional zones as sampling points from a large-scale broiler slaughterhouse.The BIOLOG microbiological automatic analyzer was used for thefirst time to identify the species of bacteria isolated and cultured at each sampling point.A total of 47 bacterial genera were identified with a much higher proportion of Gram positive bacteria than Gram negative bacteria.Among all monitored air bacteria,the dominant genera are Micrococcus,Staphylococcus,Bacillus,Corynebacterium,andPseudomonas,with 20%to 30%beingMicrococcus;12 genera of fungi were identified,with the dominant fungi being Cladosporium,Penicillium,Alternaria,Aspergillus,and Nosporing isolates;The slaughtering activities in this broiler slaughterhouse have not had any adverse effects on the air environment.With the rapid development of animal husbandry production activities and the layout design and planning of slaughterhouses,the environmental pollution caused by animal slaughter and processing should receive more attention.
