以从小麦、玉米、大米、大麦等作物中分离得到的12株不同种类的镰刀菌菌株为研究对象,探究不同温度和p H对其生长及产毒的影响。结果表明,镰刀菌在10~35℃和p H3~11范围内均能够生长,最适温度为20~30℃,最适p H为6~8。供试镰刀菌能够产生的毒素主要为A型单端孢霉烯族毒素、B型单端孢霉烯族毒素、伏马毒素和镰刀菌酸,产毒温度为5~40℃,但不同菌株的最适产毒温度存在差异;产毒过程受p H影...
本文采用7S形成纤维聚合结构的制备条件,研究低p H条件下长时间热处理对大豆蛋白7S和11S(包括酸性亚基和碱性亚基)乳化性和起泡性的影响。结果发现,低p H条件下长时间热处理的聚合手段,可以显著(p0.05)改善不同大豆蛋白组分的起泡性,但对乳化性没有明显的改善作用,甚至对乳化稳定性有降低作用,这种改善程度与是否形成纤维聚合结构无关。与p H7.0条件下的热处理手段相比,低p H条件下长时间热处...
