In this study, vitamin E species were determined as liposoluble antioxidants in amazake and changes in their compositions were examined during fermentation. Six vitamin E species were detected in brown rice amazake (BRA), and the total vitamin E content in BRA was six-fold higher than that in white rice amazake. This was consistent with the high radical scavenging capacity of BRA, which corresponded with the total levels of vitamin E and ferulic acid (FA). Although vitamin E levels in brown rice powder decreased during presaccharification, their levels were almost constant throughout saccharification and remained high in the final BRA product, suggesting the liposoluble antioxidants were stable under amazake preparation conditions. 4-Vinylguaiacol (4-VG) was found in amazake, and its content markedly increased during BRA manufacturing. Rice koji contained high levels of 4-VG produced from FA by the biological action of koji. The liposoluble antioxidative activities in BRA were due to vitamin E and 4-VG, in addition to FA, a phenolic compound thought to be the major radical scavenger. These observations suggested the superiority of traditional fermentation using koji and the advantage of BRA containing liposoluble antioxidants, such as vitamin E and FA.","PeriodicalId":89963,"journal":{"name":"Journal of bioprocessing & biotechniques","volume":"08 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2155-9821.1000317","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70318078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was based on the object to synthesize prebiotic galacto-oligosaccharides from lactose and to assess the protective role of galacto-oligosaccharide against colon cancer. Research was carried out in two phases, production of prebiotic galacto-oligosaccharide and assessment of their protective role against colon cancer. Highest %age of enzyme activity was observed at 6.5 pH and 37°C. Transgalactosylation was carried out and the process was carried out at 37°C using three different concentrations of enzyme. Animals belonging to prebiotic galacto-oligosaccharides groups (G2, G3 and G4) and inulin (Go) had significantly decreased aberrant crypt foci (ACF) counts per colon as compared to controlled animals (G1 and G5). The body mass of animals belonging to galacto-oligosaccharides (Group G2, G3 and G4) increased significantly higher as compared to control group (G1). Effect of pre-biotic treatment had significant effects on organ weights; liver, heart, spleen as well as small intestine length. In our findings galacto-oligosaccharides (GOS) were found to be protective against colon cancer however further research is needed at DNA level to find out the mutations at gene levels.","PeriodicalId":89963,"journal":{"name":"Journal of bioprocessing & biotechniques","volume":"08 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70318756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Harmful dyes such as Congo red can be removed from water using hydrogels which were developed and characterized to study efficient dye removal through adsorption mechanism. Chitosan polyacrylamide composite hydrogels showed promising results of 79% dye removal with maximum adsorption of 2.1 × 10-4 mol g-1. At pH 7, these hydrogels followed case-II diffusion mechanism and showed 185.3% swelling. Similarly, novel Nano composite hydrogels containing graphene oxide as additional component extracted from battery cells had swelling percentage of 227%. At the same pH, these hydrogels had 94.7% dye removal with adsorption of 3.5 × 10-4 mol g-1. About 200 mg of Congo red was removed by 1 g of chitosan present in the hydrogels. SEM analysis and IR spectra confirmed the adsorption of Congo red dye onto hydrogels and hydrogels demonstrating pores size of 80 μm masked by the dye particles. Anti-microbial activity was also confirmed for both hydrogels with clear zone of inhibition against E. coli JM 109. The adsorption experimental data agreed well with pseudo second order reaction kinetics and Langmuir isotherm with regression values of 97% and 99%. The applicability of these hydrogels towards adsorption of commercial dyes was also determined by using wastewater sample obtained from local fabric-dyeing vendor where the results highlighted 85% and 85% adsorption.","PeriodicalId":89963,"journal":{"name":"Journal of bioprocessing & biotechniques","volume":"205 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2155-9821.1000334","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70319134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
