Abstract:研究了以刚果红分光光度法测定麦汁及啤酒中的β－葡聚糖，探讨了实验条件，在ｐＨ８．０的条件下，刚果红和水溶性的β－葡聚糖（分子量１０３～１０４）形成有色物质，摩尔吸光系数为９．６４×（１０３～１０４）Ｌ·ｍｏｌ－１·ｃｍ－１，当参加反应的２．０ｍｌβ－葡聚糖溶液中β－葡聚糖的含量为０～１００μｇ时，反应液吸光度的变化符合比耳定律，变异系数１．１％～５．１％，标样的回收率在９０．２％～９８．６％之间，测定麦汁或啤酒中的β－葡聚糖时，变异系数为３．７％左右。

Abstract:以实验用Ｅ．ａｓｈｂｙｉＡｓ２．４８１为对象，研究了菌种特性，并对发酵培养基配方及摇瓶工艺条件进行了优化。研究结果：发酵培养基以葡萄糖、蛋白胨、玉米浆为主要原料；发酵起始ＰＨ＝６．８；５００ｍｌ和２５０ｍｌ三角瓶最佳装液量分别是６０～７０ｍｌ和２０～３０ｍｌ；接种量为１０％，在振动次数１００ｒ／ｍｉｎ，振幅８～１０ｃｍ的摇床上进行摇瓶。以豆油或油酸钠为促生因子，核黄素产量从０．１ｇ／Ｌ提高到０．６ｇ／Ｌ．

Abstract:在竹叶及其提取物中检出了相当含量的一种羟化赖氨酸—δ－ＯＨ－Ｌｙｓ，主要以游离单体和小肽的形式存在。从桂竹和金毛竹叶样分别测得其含量占干叶氨基酸总量的１．３３％和１．４０％，约相当于其中Ｌｙｓ含量的１／４．醇－水提取的过程有富集δ－ＯＨ－Ｌｙｓ的作用，其在提取物中的含量远远高于Ｌｙｓ．这一特殊的非蛋白氨基酸以相当含量存在于竹叶中，可能有着特殊的生物学意义。

Abstract:研究了工业化生产包被饲用硫酸亚铁的工艺与参数，以及包被剂的种类和用量，并以稳定性较差的ＶＡ和ＶＣ作为重点，详细研究了经工业化包被处理后的饲用硫酸亚铁的稳定性及其复配预混料中对ＶＡ，ＶＣ的稳定性的影响。结果表明，通过工业化生产的包被硫酸亚铁的纯度达到了８７．２９％，亚铁离子的含量为１７．５８％，复合预混料中载体的水份为１３．１％时，ＶＡ的留存率由原来的６．７％提高到了６３．１％，ＶＣ的留存率由原来的３．０％提高到了８．７％．首选的包被剂为包被剂Ⅰ，Ⅱ，Ⅲ．
