查询词典 maintenance

The results show that this strain was a typical acidophile with optimal growth pH being 2.0 for hypha and pH 3.0-4.0 for the spore germination. Peptone was the most suitable nitrogen source which helped produce xylanase induced by xylan during stationary phase. The resultant xylanase reacted best at 50℃-55℃ and pH 3.5, and had activities 70% after 60 min maintenance under optimum reaction conditions.

结果表明：实验菌株嗜酸，菌丝生长最适pH为2.0，孢子萌发生长适宜pH为3.0-4.0；木聚糖诱导菌体在生长稳定期大量产生木聚糖酶，蛋白胨是菌体产酶的适宜氮源；菌株所产木聚糖酶属于酸性木聚糖酶，反应最适pH3.5、最适温度50℃-55℃，在最适反应条件下保温60min，残余酶活仍接近70%，适用于较强酸性的高温加工环境。

Women are the true maintenance class.Society is built upon their acquiescence,and upon their small and necessary labors
