Research ArticleOpen accessPhrase in the titleAn Overview of the Antimicrobial Activity of Some Microbial EnzymesAkram N. Salah, Hayam Atallah AlwabsiEnzymes are substances produced by living organisms that are used to catalyze some biological and biochemical reactions as they either catalyze some types of polysaccharides and proteins or lyse complex materials such as polymers and lipids. Microbial enzymes are defined as the enzymes that can be extracted and purified from bacterial strains such as Bacillus spp., Pseudomonas spp., Streptomyces, or … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 11 Jun 2024 · 6,081 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleInfluence 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 · 6,660 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleASSESSING SOIL RESPIRATION AS AN INDICATOR OF SOIL MICROBIAL ACTIVITY IN RECLAIMED METAL CONTAMINATED LANDSKassandre Goupil, Kabwe NkongoloMining, roasting as well as smelting of these elements have caused sulphur dioxide fumigations and metal particulate depositions which have led to various detrimental effects on the overall environmental quality of the Greater Sudbury region. Soil amendment and revegetation within the Greater Sudbury Region were initiated to restore the damage land. Several methods have been used to assess the progress … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 11 Jul 2014 · 8,099 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleGlomalin Production and Microbial Activity in Soils Impacted by Gypsum Mining in a Brazilian Semiarid AreaAdalia Cavalcanti do Espírito Santo Mergulhao, Helio Almeida Burity, Fabio Sérgio Barbosa da Silva et al.Problem statement: Mining activities involve the removal of the vegetal cover and the soil organic layer, causing a severe environmental impact. In Northeast Brazil, 40% of the world’s crude gypsum is found in a semiarid area, making this region responsible for 95% of the gypsum demand in the national market. Although economically important, this activity is harmful to the environment. … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 11 Nov 2010 · 9,023 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTotal Phenolic, Resveratrol Content, Antioxidant and Antimicrobial Activity in Five Cultivars of Peanut SproutsQing Liu, Shaoqi Li, Yao Zhang et al.Peanut sprout is one of the potential natural sources of bioactive substances. In this study, five different peanut cultivars were conducted to germination, the change in total phenolic compounds, resveratrol content, antioxidant and antimicrobial activity were investigated. The sprouts of five peanut cultivars (Fuhua, Silihong, Dabaisha, Xiaobaisha and Huayu) were extracted using 75% ethanol for 3 h and the crude … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 12 Feb 2020 · 8,546 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleDRYING METHODS AND THEIR IMPLICATION ON QUALITY, QUANTITY AND ANTIMICROBIAL ACTIVITY OF THE ESSENTIAL OIL OF LAURUS NOBILIS L. FROM MOROCCOKhadija Dahak, Hafida Bouamama, Fatiha Benkhalti, Moha TaourirteThe effects of various methods of drying on the chemical quality and antimicrobial activity of the essential oil of Laurus nobilis were studied. The most prominent component in the air-dried, fresh leaf and microwave-dried leaf oils is 1,8 Cineole (58,8, 35.62 and 42,9% respectively). The essential oil has undergone significant chemical transformation in its monoterpenoids when the leaves of plant … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 20 Mar 2014 · 7,550 accessesView PDFCite
