EML8 were established using waste frying oil (WFO) as the cheap carbon source. Gas chromatography (GC) and GC mass spectrometry analysis of the medium-chain-length PHA (mcl-PHAWFO) obtained by Pseudomonas sp. EML8 of WFO indicated that it was composed of 7.28 mol% 3-hydrxoyhexanoate, 39.04 mol% 3-hydroxyoctanoate, 37.11 mol% 3-hydroxydecanoate, and 16.58 mol% 3-hydroxvdodecanoate monomers. When Pseudomonas sp. EML8 were culture in flask, the maximum dry cell weight (DCW) and the mclPHAWFO yield (g/l) were showed under WFO (20 g/l), (NH4)2SO4 (0.5 g/l), pH 7, and 25°C culture conditions. Based on this, the highest DCW, mcl-PHAWFO content, and mcl-PHAWFO yield from 3-l-jar fermentation was obtained after 48 hr. Similar results were obtained using 20 g/l of fresh frying oil (FFO) as a control carbon source. In this case, the DCW, the mcl-PHAFFO content, and the mcl-PHAFFO yields were 2.7 g/l, 62 wt%, and 1.6 g/l, respectively. Gel permeation chromatography analysis confirmed the average molecular weight of the mcl-PHAWFO and mcl-PHAFFO to be between 165-175 kDa. Thermogravimetric analysis showed decomposition temperature values of 260°C and 274.7°C for mclPHAWFO and mcl-PHAFFO, respectively. In conclusion, Pseudomonas sp. EML8 and WFO could be suggested as a new candidate and substrate for the industrial production of PHA.","PeriodicalId":16322,"journal":{"name":"Journal of Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77177833","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}

Genomic DNA was extracted from the salted opossum shrimp. The COI gene was used to amplify 519 base pairs (bp) using specific primers. The amplified products were digested by Acc I and Hinf I, and the DNA fragments were separated by automated electrophoresis for RFLP analysis. When the amplified DNA product (519 bp) was digested with Acc I, A. japonicus, A. chinensis (Korea), and A. indius (II) showed two fragments, whereas a single band of 519 bp was detected in A. chinensis (China) and A. indius (I). Also, in the RFLP patterns digested by Hinf I, A. chinensis (Korea) and A. chinensis (China) showed a single band of 519 bp, while two fragments were observed in A. japonicus and A. indius (I) and four fragments in A. indius (II). The PCR amplicon of P. gravieri was digested by Acc I into 3 bands of 271, 202, and 46 bp and by Hinf I into a single band of 519 bp. Therefore, salted opossum shrimp-specific RFLP markers showing distinct differences between four species and two sub-species by PCR-RFLP analysis. Thus, the PCR-RFLP markers developed in this study are a good method for identifying the six types of salted opossum shrimp.","PeriodicalId":16322,"journal":{"name":"Journal of Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90100253","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 experimental group was classified into the normal group (NG), the high-fat (HF) and high-cholesterol diet group (CG), the HFC and 1% fresh garlic hot water extract powder-added diet group (FGEG), and the HFC and 1% black garlic hot water extract powder-added diet group (BGEG), respectively. The serum total lipid content was 381.52±7.30 mg/ml and 368.80±4.40 mg/ml in the FGEG and the BGEG, respectively, and was significantly lower than that of the CG. The total cholesterol and triglyceride contents of the FGEG and BGEG were also significantly lower than that of the CG. The high-density lipoprotein (HDL) cholesterol was significantly higher, and the low-density lipoprotein (LDL) and the very low-density lipoprotein (VLDL) cholesterol content was lower in the FGEG and BGEG than in the CG. The serum ALT and AST activities were significantly lower than those of the CG, and especially the BGEG was lower. The total cholesterol content and the triglyceride levels of the liver tissue were 36.0% and 14.3% lower in the BGEG than in the CG, respectively. The thiobarbituric acid reactive substance (TBARS) concentrations in the serum and the liver tissue were higher in the CG than in the FGEG and BGEG, but there was no difference between them. Based on these results, garlic extract powders significantly reduced the lipid profile and increased the antioxidant activity in rats in vivo. The black garlic hot water extract powder was more effective than raw garlic because of the total number of phenolic compounds and browning substances in the black garlic.","PeriodicalId":16322,"journal":{"name":"Journal of Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86488906","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}

CP is a DNA alkylating agent that metabolizes into 4-hydrocyclophosphamide (4HCYP) and aldophosphamide in hepatocytes. However, its metabolites cause DNA synthesis disorder, leading to apoptosis and toxic side effects. The development of technology to minimize this side effect is essential to improve CP’s clinical application. Various bioactive compounds have been reported to have anti-cancer and antioxidant functions and preventive or therapeutic roles in metabolic diseases. Many researchers have attempted to minimize the side effects and improve the efficacy of these drugs together with the use of bioactive compounds. Ulmus macrocarpa Hance has been used for the treatment of edema, mastitis, stomach pain, tumors, cystitis, and other inflammatory diseases. The aim of this study was to investigate at the histological level the protective function of U. macrocarpa Hance against CP’s side effects and any potential toxic effect of U. macrocarpa Hance in the liver and kidney. Water extracts of U. macrocarpa Hance reduced CP-induced toxicity and did not induce any histological damage in the liver and kidney. Therefore, U. macrocarpa Hance would be applicable in the pharmaceutical industry.","PeriodicalId":16322,"journal":{"name":"Journal of Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91438188","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}
