芽生菌目
英文
blastomycetes-
In this study, the stem segments of new shoot with axillary buds of well - growth tetraploid black locust trees were used as explants. the effects of different basic mediums, different hormone kinds and their concentrations ratios, different sucrose concentrations on calli induction, buds differentiation and rooting in the process of establishment of high frequency regeneration system of tetraploid black locust were studied. on the base of high frequency regeneration system, the effects of various factors on transformation efficiency of badh mediated by agrobacterium tumefaciens were discussed in the light of gus histochemical assays
本實驗首先以生長良好的四倍體刺槐優株上當年生新梢的帶腋芽莖段為外植體，研究了在四倍體刺槐高頻再生體系的建立過程中不同基本培養基、不同激素濃度及其配比、不同蔗糖濃度對愈傷組織的誘導、芽的分化及生根的影響；然後在得到高頻再生體系的基礎上，通過農桿菌介導法轉化甜菜堿醛脫氫酶（ badh ）基因，以gus染色組織分析為依據探討了影響轉化效率的各種因素，建立了高效、可重復的基因轉化體系，為四倍體刺槐目的基因的導入打下了基礎。Israelensis recombinants, which contained recombinants plasmid pmt4 and pmt9 respectively, were obtained by electroporation. the bioassay results showed that the recombinants b - pmt9 and b - pmt4 had toxicities both to resistant and susceptible c. quinqnefasciatus larvae during vegetative growth stage, having the lc ? o values similar to that of. fi. sssii - 1. however, the toxic levels of the final sporulated cultures of recombinants b - pmt4 and b - pmt9 differed, with a lcso value of 2 49mg / ml for b - pmt9 and little toxicity for b - pmt4 by using the plasmid pmt9, m txl gene from b. sphaericus was ligated with p20 and cytjaa gene, giving recombinant plasmid pmpx2
含有pmt9和pmt4的大腸桿菌轉化子能表達產生mtx1毒素，發酵液對敏感和抗性致倦庫蚊幼蟲具有中度毒殺作用；含有pmt9和pmt4的蘇雲金芽孢桿菌轉化子b - pmt9和b - pmt4在營養體生長階段對敏感蚊幼和抗性幼蟲也具有毒性，毒力與野生型b . sss - 1相當，而不同轉化子在芽孢形成期的毒力因插入的mtx1基因轉錄方向不同而表現出差異，其中b - pmt4對目標蚊幼毒力極低（ lc _ （ 50 ） 10mg ml ） ，而b - pmt9對蚊幼蟲具有毒性（ lc _ （ 50 ） = 2 . 49mg ml ） 。Clostridium bacteria form hardy spores, resistant to heating and drying. in poultry, clostridium perfringens causes necrotic enteritis, currently cured with antibiotics
在家禽中，產氣莢膜梭狀芽孢桿菌會造成腸壞死，目前使用抗生素進行治療。Objective in order to look for the effective microecological bacteria for the different microbial preparation and feed additive, we investigated the differences of amylase between bacillus licheniformis, bacillus subtilis, bacillus cereus, and bacillus natto
摘要目的探索常見4種微生態制劑菌種地衣芽胞桿菌、枯草芽胞桿菌、蠟樣芽胞桿菌和納豆芽胞桿菌產生澱粉酶的能力，以篩選和研製動物微生態制劑和飼料添加劑的使用菌種。分享友人
