Effect of temperature on batch elastase production by Bacillus sp. EL31410

The production of elastase by Bacillus sp. EL31410 at various temperatures was investigated. In order to study the effect of temperature on elastase fermentation, different cultivation temperatures, ranging from 39 ℃ to 28 ℃, were evaluated in shake flask. The result indicated that 37 ℃ was best for cell growth at earlier stage; while maximum elastase activity was obtained when the cells were cultivated at 30 ℃. This result was verified by batch fermentation in 5-L bio-reactor under 37 ℃ and 30 ℃ temperature, respectively. The specific cell growth rate at 37 ℃ was higher than that at 30 ℃ during earlier stage of cultivation. The maximum value [5.5 U/(h-g DCW)] of elastase formation rate occurred at 24 h at 30 ℃ compared to 4.6 U/(h-g DCW) at 30 h at 37 ℃. Based on these results, two-stage temperature shift strategy and oscillatory temperature cultivation mode were evaluated in the next study. When compared to single temperature of 37 ℃ or 30 ℃, both two-stage temperature shift strategy and oscillatory temperature strategy improved biomass but did not yield the same result as expected for elastase production. The maximum biomass (both 8.6 g/L) was achieved at 30 h at 37 ℃, but at 42 h using two-stage temperature cultivation strategy. The highest elastase production (652 U/ml) was observed at 30 ℃ in batch process. It was concluded that cultivation at constant temperature of 30 ℃ was appropriate for elastase production by Bacillus sp. EL31410.

Studies on Pharmacokinetics of Porcine Somatotropin Liposomes

引用

Chemical Research in Chinese Universities 2005年第2期21卷 187-190页

作者： XUChuan-lai JICheng HAOKai LIXiang-qian YAOHui-yuan schooloffoodscienceandtechnology SouthernYangtzeUniversityWuxi214036P.R.China CollegeofAnimalScienceandTechnology ChinaAgriculturalUniversityBeijing100094P.R.China

This paper focuses on the pharmacokinetics in fattening pigs as well as the change of serum resulting from the use of porcine somatotropin(PST) and its liposomes. A slow-release model was determined to be relevant to following an examination of all dynamic parameters. The results indicate that the slow-release effect of PST liposomes was significant, with an extended release time of over 7 d.
