Identification of Lipopeptide Iturin A Produced by Bacillus amyloliquefaciens NCPSJ7 and Its Antifungal Activities against Fusarium oxysporum f. sp. niveum

Foods, 2022
Bacillus amyloliquefaciens NCPSJ7 showed potential fungicidal activities for the effective control of fungal infection. From the PCR test, the key genes (srfAA, sfp, fenD, bmyB, ituD, and ituC) were detected in B. amyloliquefaciens NCPSJ7.

Structure of Bacillomycin D, a New Antibiotic of the Iturin Group [PDF]

European Journal of Biochemistry, 1981
Bacillomycin D is an antifungal agent extracted from the culture medium of a strain of Bacillus subtilis. It is a mixture of two homologous lipopeptides: the lipid moiety consists of 3‐amino‐12‐methyltridecanoic acid or 3‐amino‐12‐methyltetradecanoic acid; the peptide moiety contains one residue of each of the following seven amino acid: d‐asparagine ...

Optimization of fermentation medium for Iturin A by improved artificial neural network approach

, 2015
为提高伊枯草菌素A(Iturin A)的产量,选择发酵培养基中对Iturin A合成有影响的5个组分作为自变量、以Iturin A产量为响应值,设计5因素10水平的均匀设计试验。以均匀设计试验数据为基础,分别建立二次多项式模型和一种改进型人工神经网络模型来优化发酵培养基,最后通过比较两种模型的优劣选择改进型人工神经网络模型优化培养基组分。结果表明,相比于二次多项式模型,基于相同试验设计的改进型人工神经网路模型有更好的拟合精度和泛化能力,使用人工神经网络模型优化后的培养基发酵48 h后,Iturin ...
