Abstract: The present procedure concerns a process for the purification of beta-amylases comprising treating a crude beta-amylase solution derived from wheat bran, soy bean or fresh sweet potato with an adsorbent such as bentonite, acidic clay, kaolinite and activated clay at a pH lower than 5.0 to adsorb the beta-amylases, washing out the adsorbent with water, and then eluting the adsorbed betaamylases with a solution with an ionic strength over 0.5 Mu and a pH exceeding 5.0.
Abstract translation: 本方法涉及纯化β-淀粉酶的方法,包括用pH低的吸附剂如膨润土,酸性粘土,高岭土和活性粘土处理来自麦麸,大豆或新鲜甘薯的粗β-淀粉酶溶液 超过5.0以吸附β-淀粉酶,用水洗涤吸附剂,然后用离子强度超过0.5μm并且pH超过5.0的溶液洗脱吸附的β-淀粉酶。
