中文拼音 [mǎfàngxiànjūn]
馬放線菌
英文
actinomyces caballus-
It was found out that maduramicin production strains had strong antiseptic activities against g + bacteria while maduramicin non - producing strains had no antiseptic activities. no new antibiotics proved to be produced by the result
我們對尤馬馬杜拉放線菌的產素不穩定性進行研究，同時進行馬杜黴素高產菌株的選育和發酵工藝的改良。Their life cycles and characteristics of their colonies were observed and strain s - l was found to have the typically morphological differentiation of a. yumaense. the morphological differences of every mutants and the period of morphological block were ascertained
尤馬馬杜拉放線菌（ actinomadurayumaense ）是馬杜黴素（ maduramicin ）的產生菌，有明顯的產素不穩定性，影響工業生產。After the primary and secondary selection, 7 strains were tested to have higher productivity than the starting strain. of the 7 strains, strains s1 - 007, s1 - 123 and s1 - 018 were proved to produce more maduramicin than the starting strain. compared with 6236ug / ml of the starting strain, the productivity of the above three strains reached 8020 g / ml, 8254 g / mland9175 g / ml respectively
出發菌株尤馬馬杜拉放線菌s - 1 ，經過鏈黴素抗性篩選，挑取223個菌株，經過初篩和復篩得到7株菌株馬杜黴素的產量高於出發菌株，其中3個菌株s1 - 007 、 s1 - 123和s1 - 018的產素量與出發菌株的6236ug ml相比有較大提高，分別為8020ug ml ， 8254ug ml和9175ug / ml ，尤其是突變菌株s1 - 018的產量比出發菌株高47 。
