摘要

鱼类加工业产生大量的副产品,造成严重的环境和健康问题。与废物处理有关的环境问题可以减少,因为鱼类副产品的低成本含有可以促进微生物生长和对酶生产有用的营养物质。本研究旨在研究温度和发酵时间对蜡样芽孢杆菌(Bacillus cereus)从鱼废水解物中生产蛋白酶的影响。对鱼废水解物进行预处理并继续生产蛋白酶。在30 ~ 60℃的温度范围内,每隔4 h研究发酵时间的影响,连续发酵72 h。结果表明,发酵48 h时蛋白酶产量最高,为45.63 U/mL; 50℃时蛋白酶产量最高,为44.908±6.14 U/mL。本研究为深入了解养殖条件对本地鱼废工业生产蛋白酶的影响,进一步优化研究以提高蛋白酶的产量提供了依据。

Effect of Temperature and Fermentation Time on Protease Production Using Decapterus macarellus Fish Waste
The fish processing industries generate huge amounts of by-products which cause serious environmental and health problems. The environmental problems related to waste disposal can be reduced as the low cost of fish by-products contains nutrients that can enhance microbial growth and are useful for enzyme production. This research aims to investigate the effect of temperature and fermentation time on protease production from fish waste hydrolysate by using the Bacillus strain (Bacillus cereus). The pre-treatment and fish waste hydrolysate were carried out and continued with the production of protease. The effect of fermentation time was studied every 4 h for 72 h while the effect of temperature was investigated at temperatures ranging from 30 °C to 60 °C. The results showed the maximum protease production of 45.63 U/mL at 48 h of fermentation time and 44.908 ± 6.14 U/mL at a temperature of 50 °C. The current study provides insight into the effects of cultivation conditions on protease production from local fish waste industries for further optimization study to enhance protease production.
