芽孢桿菌素 的英文怎麼說
中文拼音 [yábāogǎnjūnsù]
芽孢桿菌素
英文
bacillocin-
In the research field of food preservation, an intense interest for scientists is focused on the isolation of antimicrobial substances from microbial metabolites. natural biopreservatives derived from traditional fermented foods are generally recognized as safe. in this paper, one strain screened for its safety and broad antimicrobial spectrum and its antimicrobial substance - - bacteriocin are studied in detail

因此，推測可能存在中性粒細胞減少，功能被過多的胰島素抑制，芽孢桿菌可以乘虛而入，很有可能通過腸內壁粘膜微破損進入循環。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。Mtxl ( 100 - kilodalton mosquitocidal toxin ) is a kind of toxin synthesized in vegetative growth stage of bacillus sphaericus ( b. s ). the purified mtxl has the same toxicity as the binary toxin from b. s
Mtx1 （ 100kdmosquitocidaltoxin ）殺蚊毒素是一種在球形芽孢桿菌（ bacillussphaericus ， b . s ）營養體期表達的毒素蛋白，其純化蛋白對蚊幼的毒力與二元毒素相當。Bacillus subtilis can hydrolyze phytate, release phosphorus and improve phosphorus nutrition of plants and animals by secreting phytases
摘要枯草芽孢桿菌通能過分泌植酸酶分解植酸，釋放磷元素，促進動植物磷的吸收。With the aim of increasing the expression and stability of mtxl, the mtxl gene originated from b. sphaericus ssii1 was cloned to a shuttle vector pbu4. two recombinant plasmids pmt9 and pmt4 were obtained, with the inserted fragments in the opposite orientations
為了提高mtx1殺蚊毒素蛋白的表達量和穩定性，本文將來源於球形芽孢桿菌b . sss - 1的mtx1毒素基因克隆至穿梭載體pbu4上，得到mtx1插入方向相反的重組質粒pmt9和pmt4 。A polypeptide with sequence of qkvdssggggs was designed to be a linker between c terminal of penicillin g acylase and n terminal of the coat protein. the ribosome binding site ( rbs sequence ) of psurfscript is also replaced by rbs sequence originating from bacillus subtilis. it was demonstrated that constructed phagemid can still express penicillin g acylase
