Research ArticleOpen accessIn the abstractEffects of Soil Storage at Freezing Temperatures on Soil Enzymatic ActivitiesAinsley Lougheed, Kabwe NkongoloSoil enzyme activities are good indicators of soil health. It has been hypothesized that soil storage before analysis might affect microbial function. The objective of the present study was to determine if soil storage at -20 and -80°C affects soil enzymatic activities. Soil samples were collected and stored for four weeks at -20 and -80°C. Activities of nine enzymes were … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 12 Aug 2024 · 4,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Analysis of Bifidobacteriaceae in a Fermented Milk and Colostrum Product in Relation to Immune FunctionMarco RuggieroThis study investigates the microbial composition of a commercially available Swiss fermented milk and colostrum product with a history of use in chronic condition management since 2014. The analysis, performed using the Axiom Microbiome Array, identified a high number of targets corresponding to microbial species classified as probiotics belonging to the Bifidobacteriaceae family. The array provided 28 unique targets, each … …American Journal of Immunology, Vol. 19, Issue 1 · 2 Aug 2024 · 9,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization and Molecular Identification of Protease-Producing Thermophilic Bacterial Isolate TUA-26Anthoni Agustien, Mufidhatul Muqarramah, Feskaharny AlamsjahProtease enzymes are used as biocatalysts that can accelerate a reaction. Thermostable enzymes produced by thermophilic bacteria are needed in the industrial field because of their ability to withstand high temperatures. The thermophilic bacterial isolate TUA-26 that produces protease was to analyze the optimum conditions of temperature, pH, agitation, trace elements, carbon sources, and nitrogen sources; the stability of protease … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 6 Apr 2024 · 4,937 accessesView PDFCite
Review ArticleOpen accessIn the abstractLupane-Type Triterpenoids BiotransformationZhumadilov Sayat Sagatovich, Bakibaev Abdigali Abdimanapovich, Zhadan Konstantin Vasilevich et al.A lot of scientific material has been accumulated in recent years about the biotransformation processes of lupine-type triterpenoids. The novelty of this review is the summary of these works, the analysis and identification of the most suitable biocatalysts for future researchers, and the presentation of development trends for new derivatives. The known biotransformation examples of the most common lupine-type triterpenoid … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 12 Dec 2023 · 4,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mercuric Ion on the Oxidant Response and Calcium Ion in the Protoplasts of Arabidopsis ThalianaJun Xing, Rui Wu, Hui Yu et al.As a non-essential element for plant growth and development, the heavy metal mercury (Hg) has significant toxicity to plants. The aim of this study was to investigate the effect of mercuric ion (Hg2+) on the oxidant response and calcium ion (Ca2+) in the protoplasts of Arabidopsis thaliana. The protoplast cells were exposed to 5.0, 10.0, and 20.0 mmol/L Hg2+ for … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 29 Aug 2023 · 4,966 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 · 6,316 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Decreasing Temperature on Soil Microbial Activity in a Boreal Shield EcozoneAlistar Moy, Kabwe NkongoloAlthough the focus on warming is imperative to address climate change, addressing the effects of cooling is arguably just as relevant in characterizing the enzyme response to temperature fluctuations. In this study, the response of enzyme activity to diminishing temperatures in the field was evaluated. The targeted sites were located in the City of Greater Sudbury in Northern Ontario, Canada. … …American Journal of Environmental Sciences, Vol. 18, Issue 2 · 17 Apr 2022 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicroflora Contribution to Cellulase and Digestion Enzyme in Mud Crab Digestive TractSiti Aslamyah, Yushinta Fujaya, Nita RukminasariMicroflora in the digestive tract of aquatic animals is thought to be not only the microbes that contribute to the production of cellulase enzymes but also contribute to other digestive enzymes, such as protease, amylase and lipase. This study aims to examine the microflora contribution to the mud crab’s digestive tract. Scylla sp. were maintained in the crab box individually … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 26 Mar 2021 · 6,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnticonvulsant Activity of Hydroalcoholic Phoenix dactylifera Fruit Extract and Pimpinella anisum Oil in MiceSameh Mohamed Mostafa EL-Nabtity, Ahmed Shaban Abdelaziz, Manar Salah Moselhi, Mario GiorgiEpilepsy is a group of long-term neurological disorders characterized by epileptic seizures. The present study sought to investigate the anticonvulsant and neuroprotective Activity of Hydroalcoholic Phoenix dactylifera fruit extract (HAPD) and Pimpinella Anisum Oil (PAO) against Pentylenetetrazole (PTZ) and Maximal Electric Shock (MES) induced a seizure in mice. Mice groups were treated with HAPD1000 mg/kg, PAO 4 ml/kg. The onset … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 25 May 2019 · 7,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractOxidative Stress and Reproductive Damage Induced by Lead Acetate in Female Guinea Pig (Cavia porcellus): Curative Effects of Hydroethanolic Extract of Spirulina platensisDeutcheu Nienga Sorelle, Ngoula Ferdinand, Manfo Tsague Faustin Pascal et al.This study was aimed at evaluating the curative effects of Hydroethanolic Extract Of Spirulina platensis (HESP) on the reproductive function of female Guinea pig exposed to oxidative stress.
