中空球形壳聚糖的制备及在固定化红酵母生产L-苯丙氨酸中的应用
Preparation of Hollow Globular Chitosan and Its Application in Producing L-phenylalanine and Immobilizing Red Yeast Cell
【摘要】 报道了壳聚糖溶液注射到含有质量浓度为 30 %的甲醇和质量浓度为 2 0 %的 Na OH的溶液中制成中空球形壳聚糖 ,经质量浓度为 0 .4%的戊二醛交联 ,固定化红酵酶生产 L-苯丙氨酸 ,转化率为 82 .4%。
【Abstract】 A method of preparing hollow globular chitosan is studied: inject 25% chitosan into 20% NaOH and 30% CH 3OH solution to prepare hollow globular chitosan, and then the chitosan is treated with 0.4% gluluraldehyde to immobilize red yeast and produce L phenylalanine.
