However, citrinin, produced in the growth process of monascus, is a mycotoxin and will induce teratogenicity, carcinogenicity and mutagencity
桔黴素是一種真菌毒素，作用的靶器官是腎臟，可以致畸、誘發腫瘤、突變等。The morphological, physiological, biochemical and genetic diversities between bacillus thuringiensis wild - type strain ybt - 1463 and its plasmid - free mutant bmb171 was comparatively studied. it showed that the plasmid - free mutant strain bmb171 lost the ability to form the parasporal crystal, but there was on obvious diversities were observed on the sensitivity to 10 antibiotics, the utilization of 19 carbon sources and 12 nitrogen sources, as well as the growth properties between ybt - 1463 and bmb171, whereas the electro - transformation frequencies of bmb171 were much higher than those of ybt - 1463, respectively with 5 exogenous plasmids as the donor dnas
對出發菌株ybt - 1463和其無質粒突變株bmb171的部分形態、生理生化和遺傳學特性進行的比較研究的結果表明，突變株bmb171不形成伴胞晶體，但在個體形態與菌落特徵、對紅黴素等10種抗生素的敏感性、對葡萄糖等19種碳源和谷氨酸等12種氮源的利用能力及生長性能與出發菌株ybt - 1463無明顯差異。Using " shanghai no. 4 " and " dongcun jiaopei " as donor materials, variants with improved heat tolerance were obtained through treating haploid stem apexes with pingyangmycin and then culturing survived stem apexes with stress of higher temperature
摘要用平陽黴素對青花菜「上海4號」和「東村交配」的單倍體莖尖進行誘變處理，以高溫作為選擇壓力，獲得一批耐熱性明顯比原始品種提高的單倍體變異體。S. lividans mutant strains zx1 ( dnd cluster deleted ) and zx64 ( dnda disrupted ) had pleiotropic mutations including low mel expression and poor sporulation. it was speculated that dnda together with its downstream dna ( 2. 5kb ) might be involved in these two phenotypes because dnda together with its downstream dna could restore normal sporulation and mel expression to zx64, while dndb and dndc had no such effect because lai and la2 showed no obvious difference in these two phenotypes from wild type s. lividans 1326
另外通過比較這幾個突變株及野生型菌株在產孢和黑色素基因（ mel ）表達方面的差異，推測dnda及其下游區域與變鉛青鏈黴菌的產孢和刺激外源黑色素基因的表達有關，而dndb和dndc則與之無關，因為la1和la2在這兩種表型上與野生型菌株無明顯差異。The influence of cytosintetidemycin on activity of defense enzymes ( cat pod ppo pal, sod and 1, 3 glucanase ) was studied, results suggested that the activity of defense enzymes was much more easily to be stimulated by cytosintetidemycin, and the level of 1, 3 glucanase activity was also induced
摘要用嘧肽黴素處理辣椒植株后，測定了辣椒葉片組織內各種防禦酶系（苯丙氨酸解氨酶、超氧化物歧化酶、過氧化氫酶、過氧化物酶、 - 1 ， 3葡聚糖酶）的活性變化。Streptomyces hygroscopicus subsp. yingchengensis 10 - 22 is an important agricultural strain which produces at least four antifungal antibiotics named as antibiotic 5102 - i, 5102 - ii, 5102 - iii, 5102 - iv respectively
吸水鏈黴菌應城變種10 - 22是一種有用的農用抗生素產生菌，它可以產生至少四類抗真菌抗生素，分別命名為5102 ?號、 5102 ?號、 5102 ?號、 5102 ?號抗生素。Then, tlc was used to purify them, and antibiotic experiments were made to define which was the main antibiotic substance. results showed, orange pigment was the major antibiotic substance, and it could inhibit bacteria, but had no effect on yeasts and algae. the diameter of the inhibition zone was directly proportional to the value of absorption of orange pigment
（ 2 ）利用吸附柱分離三種色素，並用tlc法純化，刮取相應的色素點， 70乙醇溶解，濃縮，進行抑菌實驗，證實橙色素是主要的抑菌物質，對細菌具有較強的抑制效果，其抑菌性與其吸光度呈正比變化，橙色素對酵母菌和黴菌無抑制效果。分享友人
