摘　　要：短短芽胞杆菌分布广泛,并且在不同生长阶段,菌落形态也有所不同。目前已经完成2株短短芽胞杆菌的全基因组测序,但只对短短芽胞杆菌部分基因的功能进行了研究,如编码二硫化物氧化还原酶的基因bdb、α-乙酰乳酸脱羧酶的基因aldB、耐碱性木聚糖酶xylB基因和细胞壁的合成基因等,特别是具有抗菌活性的短杆菌酪肽的合成过程及所需酶的基因均有研究。短短芽胞杆菌在生物防治、作为分泌表达外源蛋白的宿主及环境治理等领域有广泛应用前景。Brevibacillus brevis is widely distributed. In different growth stages, the colony morphology would present diversity. At present, the whole genomic sequences of two B. brevis strains were sequenced, only a number of functional genes of B. brevis have been studied, such as bdb gene which encoded thiol-disulfide oxidoreductase, aldB gene which encoded α-acetolactate decarboxylase,xylB gene which encoded alkaline xylanase and the synthesis of cell wall genes. Genes expressed in tyrocidine synthesis process and its required enzymes have also been studied. B. brevis was used in lots of fields, such as biological control, as host bacteria for extracellular production of foreign proteins, and microbial degradation etc, it wonld have broad application prospects.
