| 1 | Optimization and kinetic studies for enzymatic hydrolysis and fermentation of colocynthis vulgaris Shrad seeds shell for bioethanol production显示文摘The key process parameters for the hydrolysis and fermentation of Colocynthis vulgaris Shrad seeds shell(CVSSS)were optimized using the Box-Behnken Design(BBD)of Response Surface Methodology(RSM).Kinetic study was also carried out.The proximate analysis of the CVSSS was done by the method of the Association of Organic and Applied Chemistry(AOAC).Enzymatic hydrolysis was experimented by using Aspergillus Niger as a crude enzyme isolated from soil at sawdust dump site and screened for cellulosic activities.Factors that affected the hydrolysis of the CVSSS were screened by using the Greco-Latin square design of experiment.However,for Saccharomyces cerevisiae,factors that affected the fermentation of the CVSSS were screened by using the same Greco-Latin square design of experiment.Meanwhile,the result of the proximate analysis revealed that the CVSSS had 73.54%cellulose which could be converted to bioethanol.It was established that temperature,pH and time had significant effect on hydrolysis,while the optimum results were obtained at 46.8℃,3.32 d,5.68 and 59.87%for temperature,time,pH and glucose yield,respectively.Temperature,yeast dosage,pH and time had significant effect on fermentation,while the optimum results from optimization were found to be 33.58℃,7.0,3.55 d,1.65 g per 50 mL and 25.6%for temperature,pH,time,yeast dosage and ethanol yield,respectively.The kinetics of both the enzymatic hydrolysis and fermentation agreed with the Michealis-Menten kinetic model with the correlation coefficients(R^(2))of 0.9708 and 0.8773,respectively.However,from the error analysis,the experimental and predicted values had a very good relationship as described by Michaelis-Menten model. | Igwilo Christopher Nnaemeka Egbuna Samuel O Onoh Maxwell I Asadu OChristain Onyekwulu Chinelo S | 2021 | Journal of Bioresources and Bioproducts2021，6，1： | 3 |

| 15 | 黄粉虫替代蛋白质饲料对太平洋白虾(凡纳滨对虾)消化性能的影响显示文摘试验旨在评估黄粉虫粉(MM)作为凡纳滨对虾养殖中蛋白质来源的可行性。饲料分为正常饲料和试验饲粮,试验饲料中包含正常饲料85%和MM 15%,两种饲料中均含有氧化铬0.5%作为惰性标记,试验采用表观消化率系数(ADC)对两种饲料进行检测。为评估MM消化价值,对虾饲料中采用鱼粉替代MM,替代比例分别为0%、25%、50%、75%和100%,在清水中饲养6周后,对生长参数和整个虾体成分进行评估。干物质ADC为45.9%,能量ADC为66.5%,粗蛋白质ADC为76.1%,必须氨基酸ADC为72%~86%。MM中蛋氨酸为第一限制性氨基酸。饲料中添加MM后,各组间对虾的体增重、特定生长率、采食量、饲料转化率、存活率和蛋白质合成率均无显著变化(P>0.05),虾体蛋白质含量无显著差异(P>0.05)。而随着鱼粉替代比例上升,虾体脂含量从1.13%升至1.88%。结果表明,黄粉虫粉可作为凡纳滨对虾饲料中的替代蛋白质饲料,但添加时应注意补充蛋氨酸。 | Panini R L Freitas L E L Guimarǎes A M Rios C da Silva M F O Vieira F N Fracalossi D M Samuels R I | 2017 | 饲料博览2017，0，7： | 1 |
