v.過度地生產(chǎn)
Using Penicillium notatum 9606 as starting strain,mutagenized with UV,a mutant HW2203 overproducing GOD was obtained. 采用紫外線誘變方法,對點青霉9606菌株進行誘變處理,獲得了高產(chǎn)葡萄糖氧化酶菌株HW2203。
The red algae are overproducing, we must clear the reservoir as soon as possible. 紅藻過度繁殖，我們必須盡早清庫。
Taking Bacillus thuringiensis 032 which was screened out from 103 strains preserved in our laboratory as the original strain, a new strain named 032UDU with the steady capability of overproducing thuringiensin was obtained after UV and DES mutation. 在此基礎(chǔ)上采用紫外和硫酸二乙酯復(fù)合誘變的方法對菌株032進行誘變育種,得到一株遺傳穩(wěn)定的高產(chǎn)突變菌株032UDU,比出發(fā)菌株蘇云金素產(chǎn)量提高20%25。
Guanosine overproducing mutant was derived from Bacillus subtilis T1001 by using ultraviolet and diethyl sulfate (DES). The mutant was selected directionally and step wisely on the agar plates containing methionine sulfoxide(MSO) and 8 azaguanine(8 AG). 以枯草芽孢桿菌T1 0 0 1為出發(fā)菌株 ,經(jīng)紫外線、硫酸二乙酯逐級誘變處理 ,選育出腺嘌呤缺陷型 (Ade- )菌株 ,然后經(jīng)蛋氨酸亞砜 (MSO)、8 氮鳥嘌呤 ( 8 AG)結(jié)構(gòu)類似物平板定向篩選 ,獲得鳥苷高產(chǎn)菌株TA2 0 8。
Following the meeting OPEC oil ministers said they will stick to present output levels set in December. They also said they would pressure some members who have been overproducing. 歐佩克的石油部長在會議結(jié)束后表示，他們將維持去年12月設(shè)定的產(chǎn)量水平。他們還表示要向超產(chǎn)的一些成員國施加壓力。
