【摘要】 介绍了一种新型立式静态固态物料发酵罐的结构特点及工作原理,对灭菌、接种、通气等关键生产工序进行了探讨。经多批次纤维素酶的培养试验,结果表明,立式静态固态物料发酵罐实现了产生蒸气,直接对固态物料进行蒸气灭菌、冷却、接种、发酵、无菌空气的供给,杜绝杂菌污染,降低了设备造价,提高了性价比,提高了产品的产量和质量。更多还原

【Abstract】 The structure feature and working principle of a novel vertical solid state fermentation bioreactor were introduced in the paper.The critical production procedures using this bioreactor,such as sterilization,inoculation and aeration in fermentation,were also discussed.The production of cellulase was carried out in this bioreactor for many times.The results showed that the novel vertical solid state fermentation bioreactor made it possible to realize sterilization,cooling and innovulation in situ for solid materials.Moreover,the aeration in the bioreactor was well.By the use of the novel bioreactor,the mixture of hybrid bacteria was prevented,the costs for production was lowered,and the qualities and outputs of the products were improved.更多还原
