Glucose was the most abundant compound in the hydrolysate. The degradation rate of biomass was gradually increased by increasing the CSF during pretreatment. The highest ethanol production from hydrolysate was 2.79 g/L at CSF 1.89 (30 min, 82 mM oxalic acid) after 72 h fermentation. The fermentation inhibitor concentration increased by increasing the CSF. In the simultaneous saccharification and fermentation (SSF), the highest ethanol yield was 35.86% at CSF 2.18 (58 min, 82 mM oxalic acid). The optimal pretreatment condition for bioethanol production from the hydrolysate and pretreated biomass was CSF 1.89 (8.64 g/L).","PeriodicalId":331261,"journal":{"name":"Trends in Agriculture & Life Sciences","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126013609","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}

There are Cirsium pendulum, Cirsium setidens, Carduus crispus, Cirsium japonicum, Cirsium japonicum nakaisanum, and Cirsium japonicum spinosissimum . Six types of thistles leaves were extracted using 80% ethanol and among samples, Cirsium pendulum thistle showed highest silymarin content (61.2 mg/g DW), alcohol detoxification (15.2 mU/mL) and antioxidant activity (ABTS and DPPH radical scavenging effects). Also, Cirsium pendulum extract showed a 85% liver protection function over ethanol or hydrogen peroxide treated rat primary hepatocytes, similar effect with silymarin (87%) as positive control. In conclusion, those results indicated that Cirsium pendulum extract is likely a superior functional food ingre-dient with liver protection and alcohol detoxification.","PeriodicalId":331261,"journal":{"name":"Trends in Agriculture & Life Sciences","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114515744","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}

The newly developed attractant showed substantially high capture of V. velutina that was statistically supported (P < 0.01).

In this study, we have optimized culture conditions of three species, such as Bacillus subtilis, Saccharomyces cerevisiae and Lactobacillus casei that could act as effective biological agent by producing growth-promoting factors to crops. They also reduce harmful odors generated from livestock manure. We made up the optimal media recipes for Bacillus subtilis, Saccharomyces cerevisae and Lactobacillus casei named as MMS (glucose 0.5%, soy bean flour 0.8%, NaCl 0.15%, K2HPO4 0.25%, Na2CO3 0.05%, MgSO4 0.1%), YSM (dextrose 1%, soytone 0.5%, yeast extract 0.5%) and LSM (glucose 2%, soytone 0.5%, casein milk 0.5%, NaAc 0.5%, KH2PO4 0.2%, MgSO4 0.002%, MnSO4 0.05%), respectively. The culture period of three microorganisms were determined on 30 hours in 500 L fermenter. In addition, the maximal cell growth of Bacillus subtilis, Saccharomyces cerevisae and Lactobacillus casei was measured as 1.4×10 cfu/mL, 6.4×10 cfu/mL, 3.3×10 cfu/mL, respectively. From above results, we represent that development of practical media and cultural techniques can economize heavily the cost for mass production of agricultural and livestock microorganisms.
