黄曲霉毒素B1降解菌活性产物的提取及其应用性质研究
Study on extraction and applied properties of a bioactive product from an organism degrading aflatoxin B1
摘要
Abstract
A bioactive product from Stenotrophomonas sp.42-2 could degrade aflatoxin B1 (AFB1).The extraction and applied properties of the bioactive product were studied in this paper.AFB1 was effectively degraded by extracellular bioactive product from Stenotrophomonas sp.42-2.The degradation ability of the bioactive product was optimum in the 65％ saturated ammonium sulfate.The molecular mass of the bioactive product was greater than 30 kDa.The bioactive of the product was optimal at pH8.0 and at 40 ℃.Its optimal reaction time was 72 h.The activity of the bioactive product was enhanced in the presence of Mg2+,Cu2+.And Fe2+ was able to inhibit the bioactivity of the extracellular product.关键词
