Studies on screening of strains of producing phytase and the conditions of producing phytase the strains of producing phytase could be identified by the hydrolysis bound in differential medium . aspergillus niger an010001 secreting phytase was isolated by screening and second screening . the conditions of producing phytase was studied 植酸酶菌株的篩選及產酶條件的研究本項研究利用植酸酶的菌株能在篩選培養基上形成水解透明圈的特點而進行鑒定,通過初篩和復篩,得到一株產植酸酶較高的黑曲霉( aspergillusniger ) an00101菌株。

2 . according to the effect of combination of different hormone concentration in the medium on callus formation and shoot induction of tomato cotvledons , we defined mso + 2 . 0mg / l ba + - 0 . 2mg / l iaa as optimum differential medium 根據番茄子葉外植體在加有不同激素濃度配比的培養基上愈傷組織分化和芽再生的情況,確定最佳分化培養基為ms _ 0 + 2 . 0mg / lba + 0 . 2mg / liaa ; 3
