摘要
文章研究了在以葡萄糖为基质的厌氧序批操作反应器(ASBR)中糖原的储存及代谢模式,结果表明:当进水结束时,基质水解的量占36.22%,基质储存的量占50.48%。胞内糖原的代谢受到糖原总量和胞外挥发性脂肪酸(VFA)含量的影响,糖原总量和代谢速率成正比,最高可达26.36 mg/(g VSS·h);胞外VFA含量和代谢速率成反比。"快速吸收储存、缓慢利用"是微生物利用糖原的过程中的主要特点,糖原的代谢模式为"葡萄糖-胞内糖原储存-VFA"。
A bench-scale experiment was conducted for investigating the glycogen storage and metabolism model of glucose-fed(anaerobic sequencing batch reactor).The findings suggested that when turning off the influent into the ASBR,hydrolyzed substrate accounted for 36.22%and the stored substrate 50.48%of the total substrate of influent,respectively;intracellular glycogen metabolism was affected by the total amount of glycogen and extracellular volatile fatty acid(VFA),the total amount of glycogen was proportional to the amount of glycogen and glycogen metabolic rate,which could be up to 26.36mg/gVSS·h,however,extracellular VFA was inversely proportional to glycogen metabolic rate.The study concluded that intracellular glycogen utilization was characterized with'rapid absorption and storage,slow to use';and the model of glycogen metabolism was'glucose-glycogen storage-VFA'.
