Identification and partial purification of thuricin 4AJ1 produced by Bacillus thuringiensis.

Thuricin 4AJ1, produced by Bacillus thuringiensis strain 4AJ1, showed inhibition activity against Bacillus cereus 0938 and ATCC 10987. It began to appear in the stationary phase and reached its maximum activity level of 209.958 U at 18 h against B.

[Diversity of Endogeny Eumycetes in Gynostemma pentaphyllum and Its Correlation with Gypenoside XLIX].

Objective: To study the correlation between active components and endogeny eumycetes in Gynostemma pentaphyllum of different types from different habitats.

Methods: Endogeny eumycetes from different parts of Gynostemma pentaphyllum were isolated by general isolation methods. Insert method and point planting method were used for identification.
