木聚糖酶系可以将半纤维素一种多糖转化为单细胞蛋白和其他有用物质.有些嗜热菌能产生耐热木聚糖酶在食品工业上具有较高的潜在应用价值.现欲从温泉中分离能分解半纤维素的嗜热菌并从中筛选木聚糖酶高产菌株获得耐热木聚糖酶.回答下列问题1实验中接种环使用前后都在酒精灯上灼烧其目的是.2取适量体积的样品涂布在富含且其为唯一碳源的固体培养基上置于恒温培养箱中培养菌落长出后挑取单个菌落并进行一系列操作然后在培养基上用法接种培养进行菌株的.最后将得到的菌株接种到填固体或液体培养基中富集.3将富集后的菌株接种于固体培养基上待菌落长出后用0.1%的染色1h再用1mol/LNaCl脱色.菌落周围会出现筛选的菌落即为木聚糖酶高产菌株.
