摘要: 采用几丁质酶培养基筛选出FJAT-10038芽胞杆菌, 测定其几丁质酶活力为11.04U·mL-1, 说明FJAT-10038芽胞杆菌能够产几丁质酶。采用气相色谱质谱联用 (GC/MS) 的方法分析FJAT-10038发酵液丙酮萃取的成分, 初步鉴定出31种化合物。在鉴定出的化合物中, 相对含量超过10%的有2种, 分别是六氢化-吡咯环[1, 2-a]-吡嗪-1, 4-二酮和异丁醚, 相对含量分别为44.17%和15.58%;匹配率在90%以上的成分有3种, 分别是二叔丁基对甲酚、六氢化-吡咯环[1, 2-a]-吡嗪-1, 4-二酮和六氢-3-苯甲基-吡咯并[1, 2-a]-吡嗪-1-4-二酮, 匹配度分别是90%、97%和93%, 相对含量分别是0.43%、44.17%和0.38%;另外还发现一些其他的活性物质。Abstract: The chitinase activity of Paenibacillus chitinolyticus FJAT-10038 was characterized by filtering FJAT-10038 Bacillus using chitinase medium, the chitinase activity of which reached at 11.044 U mL-1.Furthermore, Acetone extracts of FJAT-10038 Bacillus were analyzed by GC-MS.Our results suggest that thirteen-one compounds are identified, and the content of Pyrrolo [1, 2-a]pyrazine-1, 4-dione, hexahydro-and Propane, 1-ethoxy-2-methyl-reached 44.1672%and 15.5814%.Meanwhile, the match degree of Butylated Hydroxytoluene, Pyrrolo [1, 2-a]pyrazine-1, 4-dione, hexahydro-and Pyrrolo [1, 2-a]pyrazine-1, 4-dione, hexahydro-3- (phenylmethyl) -were 90%;97% and 93%, with a relative amount by 0.4305%, 44.1672% and 0.3842%.In addition, some other active substances were also been characterized.
