摘要
利用涂平板法从土样中筛选出了3株能分泌植酸酶和淀粉酶的芽孢杆菌(Bacillus)菌株.此菌株接种在植酸酶检测培养基上,37℃恒温下培养86 h时,植酸水解圈最大;接种在淀粉酶检测培养基上,37℃恒温下培养24 h后,淀粉水解圈最大.
3 Bacillus strains secreting phytase and amylase were screened from soil diluting liquid with coating plate method. The results showed that when the strain was cultivated on phytase substrate at 37 ℃ for 86 hours, the size of phylate-hydrolyzed ring was the biggest, so do the one of amylum-hydrolyzed ring when strain was cultivated on amylase substrate at 37℃ for 24 hours.
