Research ArticleOpen accessEvery word in the titleTranscriptomic 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 PDF Cite

Research ArticleOpen accessEvery word in the titleKnock Down of Erythrulose Kinase (eyk1) Leads to the Enhancement of Erythritol Production in Yarrowia lipolytica Mutant Strain YE4-2Xinhe Zhao, Tianlong Huang, Yaxin Zhang et al.Erythritol is a nearly zero-calorie sweetener, which is in great demand in food and health care industry. Our previous work obtained a Yarrowia lipolytica mutant strain YE4-2 with high erythritol yield. However, its conversion rate of glucose needs further improvement. Erythrulose kinase (eyk1) participates in the early stages of erythritol catabolism; the existence of eyk1 prevents the accumulation of erythritol. … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 24 Jul 2020 · 6,750 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEthanol Production by Novel Proline Accumulating Pichia kudriavzevii Mutants Strains Tolerant to High Temperature and Ethanol StressesRika Indri Astuti, Sena Alifianti, Ratu Nabila Maisyitoh et al.Accumulation of osmoprotectant molecule, proline, has been reported to induce a stress tolerance phenotype in yeast cells. In this study, two ethanologenic isolates of yeast, Pichia kudriavzevii (R and T), both capable of using both five and six sugar compounds to produce ethanol, were mutated via ethyl methanesulfonate (EMS) treatment. Prolineaccumulating mutant strains were selected by using proline-analogue (L-azetidine-2-carboxylic acid). … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 11 Sep 2018 · 7,838 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsInfluence of Drought Stress on Growth and Yield of Soybean (Glycine max L.) Genotypes in Northern GhanaIsaac Kwahene Addai, Alhassan Bawa, Maganoba CharlesStudies on induced mutation were conducted and the results indicated that stable, but desirable soybean mutant genotypes with improved agronomic traits have been produced. A series of evaluations of these mutant genotypes had earlier on been carried out and high-yielding ones such as 150, 200, 250, and 300 Gy have been identified. In the present study, the above genotypes were … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 1 Jun 2023 · 6,777 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPrediction of Days After Anthesis of Developing Tomato (Solanum lycopersicum) Fruit from Blossom-End Changes in ColorTiznado-Hernández Martín Ernesto, Delia Moreno-Velázquez, Angel Javier Ojeda-Contreras, Andrés Ochoa-MezaThe development of mathematical models to predict the physiological status of a developing fruit can be a useful tool to reduce the variation in fruit response to postharvest treatments. The objective of this study was to develop a mathematical model to predict Days After Anthesis (DAA) in tomato fruit from changes in the blossom end color. Around 160 tomato flowers … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 4 Sep 2013 · 8,105 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAssessment of Site Specific Mutational Effect on Transcription Initiation at Escherichia coli PromoterS. Kannan, M. Krishnan, S. Sundarraj et al.Problem statement: It is widely accepted thought that the weak promoters control the RNA synthesis and play regulatory role in complex genetic networks in bacterial system. An experiment had been designed to address whether mutations in the -16/-17 region affect the rate of transcription at an activator-independent promoter in E. coli or not? Approach: The aim of this study was … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 7,555 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsOccurrence of Avian Influenza H5N1 among Chicken, Duck Farms and Human in EgyptMohamed S. Diab, Mohamed S. Abd El Hafez, Mohamed A. Ashry, Wael K. ElfeilAvian influenza (AI) H5N1 virus consider a potential threat to the poultry industry with sever zoonotic effect associated with a high risk on human being associated with the poultry production. The disease become endemic in Egypt and cause more than 359 confirmed human infection cases in the last few years. Samples (serum and tissues) collected from 160 poultry farms that … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 1 · 22 Feb 2019 · 7,643 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy on the Polyploidy Induction of Herbicides on Hengshan Astragalus MembranaceusJianxia Liu, Yanmao Gao, Lizhen Liu et al.Studying medicinal polyploid plants is of great significance for the cultivation of traditional Chinese medicine varieties and the extraction of active ingredients. The polyploidization of A. membranaceus (Astragalus membranaceus) was induced using two treatment methods: oryzalin and pendimethalin as mutagens. The results showed that in the same method, the induction effect of polyploidy was affected by the concentration of reagents … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 14 Apr 2026 · 1,535 accessesView PDF Cite

Literature ReviewOpen accessIn the abstractPotential Therapies for Mitochondrial Diseases Caused by mtDNA MutationsAnastasia V. Poznyak, Nikolay A. Orekhov, Dmitry Felixovich Beloyartsev et al.Mitochondrial diseases, caused by mutations in mitochondrial DNA (mtDNA), present significant genetic and clinical complexities that challenge accurate diagnosis and treatment. This review examines the critical molecular mechanisms underlying these disorders, particularly the role of heteroplasmy, where mixtures of mutated and normal mtDNA influence disease severity, and the nuclear-mitochondrial DNA interactions that compound diagnostic and therapeutic challenges. The threshold effect, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,735 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiodegradation of Low-Density Polyethylene Film by UV Irradiated and Non-Irradiated Pseudomonas Aeruginosa D5Olusola Adeoye Oluwole, Temitayo Omotunde Olowomofe, Ikeoluwa Gloria OlaniyanLow-density polyethylene (LDPE) constitutes 60% of total plastic production, and non-degradable polyethylene carry bags are the most common type of solid waste found. Their recalcitrance in the environment is thus a major concern for environmentalists. This study investigated the potential of Ultraviolet (UV) induced mutation in enhancing biodegradation of LDPE films by two diesel degrading bacteria, Alcaligenes faecalis D4 and … …Current Research in Microbiology, Vol. 8, Issue 1 · 8 Oct 2025 · 3,629 accessesView PDF Cite
