氯过氧化物酶(Chloroperoxidase,CPO)是由海洋真菌烟卡尔酵母(Caldariomycesfumago,Leptoxyphiumfumago)分泌的一种多功能酶。然而,酶的应用受到其高价格的阻碍,这是由于昂贵的劳动密集型纯化过程。下游工艺的一个挑战是去除与活性酶形成复合物的共同产生的黑色色素。虽然菌株开发可以被认为是减少干扰色素合成的一种选择,但微生物的代谢也可以通过使用真菌的生物膜生长模式来改变。本研究的目的是减少CPO合成过程中的色素形成。我们首次研究了C.通过不同微结构不锈钢表面(材料编号:1.4571; AISI 316 Ti)的存在引发烟曲霉生物膜生长。C.当作为生物膜或在悬浮液中生长时,fumago是相似的,而在中等结构的表面上生长的细胞(Ra= 0.13 ± 0.02 μm)大大减少了色素形成。生物膜生长的可能性,改变细胞特性和连续发酵进行了讨论。
Chloroperoxidase (CPO) is a versatile enzyme, which is secreted by the marine fungusCaldariomyces fumago(Leptoxyphium fumago). However, the application of the enzyme is hampered by its high price, which is due to the costly, labor‐intensive purification process. One challenge of the downstream process is the removal of a coproduced black pigment that forms a complex with the active enzyme. While strain development can be considered as an option to reduce the synthesis of the interfering pigment, the metabolism of the microorganism can be altered alternatively by using the biofilm growth mode of the fungus. The aim of this study was to reduce pigment formation during CPO synthesis. We investigated for the first time CPO production duringC. fumagobiofilm growth initiated through the presence of different microstructured stainless steel surfaces (material number: 1.4571; AISI 316Ti). CPO production byC. fumagowas similar when grown as a biofilm or in suspension, whereas pigment formation was drastically reduced by cells grown on moderately structured surfaces (Ra= 0.13 ± 0.02 μm). The possibilities of biofilm growth for changing cell properties and for continuous fermentation are discussed.
