一株热噬淀粉芽孢杆菌的分离和鉴定
Isolation and Identification of Bacillus thermoamylovorans
摘要
Abstract
This study aimed to identify microbes that could , at high temperatures , efficiently degrade waste materials from livestock and poultry slaughterhouses . A stepwise gradient heating was applied to screen microorganisms and isolated HL8103 . Through colony morphology , strain morphology , physiological and biochemical characteristics ,16S rDNA sequence ,phylogenetic analysis .At the same time ,the strain was tested for its suitability for livestock and poultry slaughterhouse waste . The results identified HL8103 as Bacillus thermoamylovorans ,a gram-positive with straight or curved rod-shape bacterium that had near spherical spores , proximal birth ,and inflated cysts .Meanwhile ,HL8103 was tested for its adaptability on the slaughterhouse waste and found that it could grow well between 75℃ and 85℃ and withstand a temperature as high as 95℃ .And ,for optimal results ,the medium was to be adjusted to pH 6.8-7.2 and fermented for 18 h .关键词
