对在4、15、22、-18℃保存不同时间的菲律宾蛤仔、栉孔扇贝和长竹蛏体内细菌总数和大肠菌群的含量进行测定,研究不同保存条件下贝类体内微生物变化规律.发现-18℃保存超过24h导致贝类体内细菌含母的降低;其他各实验温度下保存的贝类,在12h内细菌总数没有明显变化;4℃保存24h内大肠菌群的含量没有明显变化.22℃保存的贝类活体体内的细菌总数和大肠菌群含量呈正相关.实验结果表明,4℃保存12h以内对贝类体内微生物无显著影响.结合其他研究结果可以推断,贝类在更接近于0℃的环境下,体内微生物的原始状态可以保持更长时间.

In order to investigate the changing trend of microorganisms in shellfish, total number of bacteria and coliform in 3 species of shellfish such as Ruditapes philippinarum, Chlamysfarreri and Solen gouldii Conrada stored at-18, 4, 15 ℃ and 22 ℃ for different periods were determined. Results indicated that an obvious decrease in total number of bacteria in shellfish stored at-18℃ for more than 24 h was observed; in contrast, no obvious change in shellfish stored at other temperature conditions for 12 h or at 4 ℃ for 24 h was observed. Moreover, a positive correlation between total number of bacteria and coliform group in shellfish stored at 22 ℃ was also observed. Taken together, the original status of microorganisms present in shellfish can be remained for a longer period of time at the environmental condition of 0 ℃.
