In summer, using half - underground pool to have solid - state alcoholic fermentation. result showed : the temperature of half - underground pool was 2 - 3 lower than ground pool, the alcoholic strength proved 29 %, acidity descended 40 %, productivity of vinegar proved 5. 17 %
夏季利用半地下酒化池進行固態法酒精發酵，結果表明：半地下池較地上池酒醅發酵溫度下降2 3 ，酒醅酒度提高29 % ，酒醅酸度下降40 % ，食醋產量提高5 . 17 % 。 -
Induced either by iptg or l - tryptophan in the absence of easily metabolized carbon such as glucose the strain bl21 ( de3 ) / pet28c - tnaa can express tryptopanase. the fermentation conditions were optimized respectively. in the presence of glucose and iptg as induce agent, the concentration is the crucial factor for expression of active tryptophanase. if the iptg concentration is less than 0. 2mm, the optimum temperature is 37 lower temperature is necessary to obtain active tryptophanase in the case of higher concentration of iptg
用iptg誘導表達實驗結果表明：利用t7啟動子在胞內能表達出有活性的酶； iptg與溫度的合適組合可以得到較高活性的色氨酸酶，在0 . 2mm以下濃度的iptg誘導時， 37是最適溫度，而用較高濃度的iptg誘導，低溫是表達有活性的色氨酸酶的必要條件，而且誘導時間要短。 -
