Research ArticleOpen accessPhrase in the titleThermodynamic Inference of the Antioxidant Process of Malic Acid and Its Structural AnalogsHan Wu, Wenhao Dong et al.Two structural analogs of Malic Acid (MA), 2-isopropylmalic Acid (2-IPMA), and 3-isopropylmalic Acid (3-IPMA) were recently identified and separated from wine. Although they have been shown to have antioxidant activity, the mechanism of their actions is still unclear. Antioxidant activities of 2-IPMA and MA were tested through DPPH, ABTS, and PTIO methods and the antioxidant-related thermodynamic properties were evaluated using … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 30 Oct 2024 · 4,824 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnhanced Fatty Acid Production in Escherichia coli by Over-Expression of NADPH Generating EnzymesYuanda Song, Yong Q. Chen, Haiqin Chen et al.NADPH is an essential factor for Fatty Acid (FA) biosynthesis. The effect of NADPH generating enzymes [NADP+-dependent malic enzyme (NADP-ME), NADP+-dependent isocitrate dehydrogenase (NADP-IDH), Glucose 6-Phosphate Dehydrogenase (GPD) and 6-Phosphogluconate Dehydrogenase (PGD)] on FA biosynthesis was investigated in an engineered Escherichia coli BL21 △fadE/pTE. Among NADPH-generating enzymes, GPD and ICD increased total FA production by 60 and 16% respectively. Especially … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 23 Oct 2017 · 8,578 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAntibacterial and Antioxidant Activities of Banana (Musa, AAA cv. Cavendish) Fruits PeelMatook Saif Mokbel, Fumio HashinagaThe fresh green and yellow banana peel of, (Musa, cv. Cavendish) fruits were treated with 70% acetone, which were partitioned with chloroform (CHCl3) and ethyl acetate (EtOAc), sequentially. The antioxidant activities of the extracts were evaluated by using the thiocyanate method, β-carotene bleaching method and 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical elimination. While, antimicrobial activities of the extracts and isolated components were … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 16,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Enzymatic Role of Lipid Metabolism in Yarrowia lipolytica Grown on GlycerolRuixue Wang, Feifei Xin, Yufei Chang et al.More attention has been paid to the production of commercial fatty acids by microbial fermentation. The basic biochemistry of lipid accumulation in oleaginous microorganisms under nitrogen limitation has been extensively studied. As an oleaginous microorganism, Yarrowia lipolytica can produce fatty acid-derived biofuels and biochemicals. However, the response of the enzymes in Y. lipolytica to glycerol remains unclear. Therefore, we aimed … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 2 · 17 Apr 2023 · 6,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractTranscriptomic Analysis of the Erythritol High-Yielding Mutant Strain Yarrowia lipolytica Y44Xiaojie Ren, Heng Ban, Chao Huang et al.RNA-seq technique was used to analyze the transcriptomics of Yarrowia lipolytica control strain Po1g, an erythritol-producing natural isolate Yarrowia lipolytica Y 22 and an erythritol high-yielding mutant strain Y44 derived from Y 22. Functional annotation of genes and classification of metabolic pathways were carried out to identify Differentially Expressed Genes (DEGs). These DEGs were classified into related metabolic pathways to … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Dec 2021 · 6,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on Carbon Source Screening Technology for Prevention and Control of Banana Fusarium WiltJin Li, Tingting Duan, Zhong Lin et al.With the spread of banana Fusarium wilt and the aggravation of the damage, it has become the biggest threat to the banana industry. Many studies have shown that bio-organic fertilizer plays an important role in the prevention and control of banana wilt, but most studies focused on biocontrol bacterium screening, not screening carbon sources that could prevent banana wilt, which … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 5 Mar 2020 · 7,263 accessesView PDFCite
