在这项研究中，提出了两种酸水解工艺，工艺A和工艺B，以生产低成本的营养素生产乳酸。工艺A为直接稀酸水解法，工艺B为工艺A加鱼渣预处理（水提）。这两种方法都可以处理鱼废弃物作为促进乳酸产生的合适营养源。由于预处理对鱼废物水解液（FWH）有一定的促进作用，工艺B使乳酸产率提高了22%。工艺B水解的6.8%FWH与20 g/L酵母抽提物（YE）相比，乳酸产量更高，说明工艺B适合生产高效乳酸生产营养素，工艺B水解的FWH可以替代YE。(c)2005爱思唯尔有限公司保留所有权利。
In this study, two acid-hydrolysis processes, process A and process B, were proposed to produce low-cost nutrients for the production of lactic acid. Process A was a direct way to hydrolyze protein with diluted acid while process B was process A plus fish wastes pretreatment (an extraction by water). The two methods could both treat fish wastes to be suitable nutrient sources for promoting lactic acid production. As the pretreatment indicated some favorable effect on fish waste hydrolyzate (FWH), process B increased lactic acid productivity by 22%. Compared with 20 g/L yeast extract (YE), 6.8% FWH hydrolyzed by process B had more efficiency in lactic acid production, indicating that process B was suitable to produce high performance nutrients for lactic acid production and FWH hydrolyzed by process B would be an substitute for YE.
