查询词典 mutant

通过平板初筛，筛选出6株对苹果炭疽病菌有较高抑菌作用的菌株，经苹果果实活体侧定从中筛选出对苹果炭疽病有较高拮抗作用的菌株BS 80-6和BS100-6。

The results showed:①Anthocyanin content in mature fruits was 132170 U·g-1FW in bud mutation which was very significantly higher than that in'Ralls'(49140 U·g-1FW);②Activities of PAL and UFGT were almost the same between the two materials, but CH I and DFR activitieswere significantly high in bud mutation, which were related to the increase of anthocyanin levels in the mutant;③Bagging treatment inhibited anthocyanin synthesis of bud mutation. But anthocyanin content had significantly increased after removing the bags. Activities of CHI and UFGT increased rap idly and were much higher than those in the control after the bag removal. The increase was consistentwith the imp rovement of anthocyanin levels.

结果显示：①在果实发育期间，芽变果皮的花青苷含量明显高于'国光'，尤其是成熟期芽变果皮花青苷含量为132170 U·g-1FW，而'国光'仅为49140 U·g-1FW；②在果实发育期间，两个品种间PAL 和UFGT的酶活性无明显差异，但芽变的CHI和DFR酶活性明显高于'国光'，表明芽变花青苷合成能力的提高与CHI和DFR酶活性高有关；③套袋抑制芽变果皮花青苷的合成，但解袋后花青苷的含量极显著升高，解袋后4种酶的变化趋势差异较大， CHI和UFGT活性均迅速升高，明显高于对照，这与解袋后花青苷迅速合成相吻合。

It is difficult to select the lactic acid high-producing strain by observing the color change zone because of spreading grow along the solid medium of Rhizopus oryzae. A serious of methods for selection and breeding of L-lactic acid high-producing mutant were developed.

米根霉在固体平板上生成的乳酸会使培养基中加入的pH指示剂变色，在菌落周围呈现出变色圈，但由于丝状真菌米根霉在固体培养基表面蔓延生长的特性，使得无法得到单菌落，进而无法通过观察变色圈与菌落直径之比来比较出各菌株产酸能力的高低。
