Combined with the recent researches , the application of static electricity equipments in fermented food production were summarized , e . g . , wine aging hastening , vinegar and raw soy sauce sterilization and saccharomyces cerevisiae mutation by static electricity , etc 摘要结合近年的研究与探索,对静电设备在酿造品生产中的应用进行了综述,如静电催陈酒类和醋类,生酱油灭菌处理以及用静电诱变酿酒酵母等。
In the bioassay using saccharomyces cerevisiae as indicator , bl10 and bl19 were found unable to produce antibiotic fr - 008 while the other four had no detectable changes in productivity . obviously , the gene replacements happened in the 5 . 2kb + 7 在以啤酒酵母为指示菌的生物测定中,未观察到基因中断菌株bl14 、 bl15 、 bl16和bl17的产素表型的变化,而bl10 、 bl19以及所有的双交换菌株都丧失了产生fr - 008的能力。
The activity of the invertase of three high - sugar saccharomyces cerevisiae strains were investigated and their amino acid sequence were determined by the use of modern biotech including enzymatic activity determination , specific pcr , the cloning sequencing and bio - information analysis etc 摘要采用现代生物技术中的酶活测定、特异pcr 、克隆测序和生物信息分析等对比研究3株高糖酵母蔗糖转换酶活性及其氨基酸序列。
Saccharomyces cerevisiae ( s . cerevisiae ) is the one ot the first and well characterized eukaryotic organisms whose complete genome was sequenced . the next chanllenge is to elucidate its gene expression pattern and the functional mechanisms of the gene products 在所有的真核生物中,人们对酿酒酵母( saccharomycescerevisiae )分子遗传学方面的认识最早,最先完成的真核生物基因组序列测定也是酿酒酵母的基因组序列。
Experiment shows that tpsl gene can endow organism the ability of synthesis trehalose , the dephosphorylation of the trehalose - 6 - phosphate is not special , and it can be replaced by other phosphatases . the tpsl gene from saccharomyces cerevisiae was cloned by pcr amplification 实验证实tps1基因就可以使生物体获得产生海藻糖的能力,酵母的海藻糖合成酶复合体中6 -磷酸-海藻糖的脱磷酸化作用是非特异性的,它可由生物体内的其它酯酶所代替。
Extracts of 10 selected chinese herb medicines ( rhizoma coptidis , cortex phellodendri , radix scutellariae , fructus forsythiae , cortex magnoliae officinails , radix glycytthizae , folium artemisiae argyi , ligustici chuanxiong rhizoma , flos lonicerae , fructus schisandrae ) were tested in vitro against six different microorganisms [ bacteria ( staphylococcus aureus , escherichia coli and bacillus subtilis ) , yeast ( saccharomyces cerevisiae ) and find ( aspergillus flavu and trichoderma viride ) 摘要本文选用黄连、黄柏、黄芩、连翘、厚朴、甘草、艾叶、川芎、金银花及五味子十味中草药水提液,对金黄色葡萄球菌、大肠杆菌、枯草芽孢杆菌、啤酒酵母、黄曲霉及绿色木霉这六种菌进行了体外抗菌试验。
