Research ArticleOpen accessEvery word in the titlePeriodic Service Behavior Strain Analysis-Based Intrusion Detection in CloudS. Priya, R. S. PonmagalThe problem of intrusion detection in cloud environments has been well studied. The presence of adversaries would challenge data security in the cloud by generating intrusion attacks towards the cloud data and should be mitigated for the development of the cloud environment. In mitigating intrusion attacks, there exist several techniques in the literature. The method uses different features like frequency … …Journal of Computer Science, Vol. 20, Issue 2 · 28 Dec 2023 · 5,087 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIdentification of a Nephropathogenic Strain of Infectious Bronchitis Virus (IBV) in Some Northern Provinces in VietnamTran Duc Hoan, Doan Thi Thao, Nguyen Dinh Nguyen et al.The nine-day-old Specific Pathogen-Free (SPF) chicken embryos were inoculated with the XDC-2 strain of Infectious Bronchitis Virus (IBV). 50% Embryo Infectious Dose (EID50) and pathological lesions were detected in the developing embryo. At the same time, 18-day-old SPF chickens were inoculated with the same strain of IBV in case of 5 chickens were injected with sterile PBS (1X, pH 7.4) … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 16 Dec 2023 · 5,910 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Adding Cellulose on Lipid Accumulation in Cellobiohydrolase and Delta-6 Desaturase Engineered Mucor circinelloides StrainsYao Zhang, Yanxia Wang et al.Despite microbial production of multifunctional gamma-linolenic acid (GLA) being an important and promising way, the high cost is still a major factor limiting industrial applications. Previously, we proposed a novel approach to promote the production of GLA from cellulose, a widely available and cheapest resource, by overexpression of the cellobiohydrolase (CBH2) and delta-6 desaturase (D6) in Mucor circinelloides. In the … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 13 Oct 2023 · 4,736 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Antioxidant and Antibacterial Activities of the Polysaccharides from Mycelium and the Culture Medium of Pleurotus Eryngii Strain UN-1Qing Liu, Haodong Wu, Ying Wu et al.Pleurotus eryngii was one of the most precious and ordinary edible mushrooms, and its polysaccharides were the major active substances. In this study, P. eryngii strain UN-1 was cultured in a liquid medium at 25℃ under a shaking of 80 rpm for 7 days. Two crude polysaccharides named CPN and CPNM were obtained from the mycelium of P. eryngii UN-1 … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 19 Jul 2022 · 6,182 accessesView PDFCite
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 · 6,119 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharacterization of a Multi-Metal Resistant Bacillus cereus Strain TWSL_5 and it’s Bioremediation Potential for Cr, Pb, Zn and FeWeerasingha Mudiyanselage Nilmini Hasintha Kumari, Naduviladath Vishvanath Chandrasekharan, Champika Dilrukshi WijayarathnaAn effluent sample collected from a textile dyeing factory was screened to isolate metal resistant endogenous bacteria using standard microbiology techniques. A bacterium with the highest metal resistance was characterized by 16S rRNA gene sequencing and the bacterial genome was screened for any possible metal resistant genes using the Polymerase Chain Reaction (PCR). The bioremoval ability of the isolate was … …American Journal of Environmental Sciences, Vol. 17, Issue 3 · 15 Jul 2021 · 6,448 accessesView PDFCite
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 · 6,753 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNovel D-Galactose Isomerases from Lactobacillus Strains Isolated from the Sweet Sap of Agave atrovirensMaría Miriam Hernández-Arroyo, Miguel Ángel Plascencia-Espinosa, María Eugenia Hidalgo-Lara et al.D-tagatose is a natural monosaccharide used as a low-calorie sugar substitute in food, beverage and pharmaceutical products. Although it is a rare sugar, it can manufacture by enzymatic isomerization of D-galactose Isomerase (D-GI). In this study, a screening was carried out to search microorganism producing D-GI in aguamiel. A rich selective medium was used in arabinose extracted from gum arabic. … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 4 · 11 Dec 2018 · 10,243 accessesView PDFCite
