    Antioxidant Enzyme Activities Estimation In vicia faba Leaves

    Get PDF
    Plant cells have the inherent ability to produce reactive oxygen species and oxygen radicals as secondary products during various physiological processes associated with abiotic stress. The disruption of the equilibrium between the generation of reactive oxygen species and the defense systems against oxidative harm is a significant consequence of abiotic stress in plants. As a consequence, the accumulation of reactive oxygen species occurs, hence triggering the onset of oxidative stress. Jasmonates represent a class of plant hormones that exert significant regulatory influence over several physiological processes. These processes include gene and metabolic regulation, immune mechanisms, responses to stress, reproductive activities, and interaction between cells, among other roles. The presence of oxidative stress induces the synthesis of metabolites possessing antioxidant characteristics and augments the efficacy of antioxidant enzymes, hence conferring a safeguarding impact on plant tissues. The aim of this study was to investigate the effects of methyl jasmonate (JAME) administration on reactive oxygen species and the activities of H2O2 scavenging enzymes, namely superoxide dismutase, catalase and glutathione in vicia faba leaves. After implementing a therapy strategy with JAME, there was an elevation in the activity levels of the enzyme superoxide dismutase , catalase , and glutathione. &nbsp

    Surface-active substances that are secreted by microorganisms are called biosurfactants. Although there are a number of known microorganisms that create biosurfactants, more research is needed to determine which ones could produce the chemical more quickly and profitably for commercial usage. These kinds of bacteria were identified in the Dutsin-Ma metropolitan investigation as being involved in the production of biosurfactant. Six soil samples in all were gathered from various locations within the Dutsin-Ma city. Six soil samples in all were gathered from various locations within the Dutsin Ma city. The tests included isolating the bacteria, identifying the group to which the organisms belong using gram staining, testing the isolated bacteria biochemically, and performing additional tests to identify bacteria that create biosurfactants. Prior to microscopic examination, the bacteria used in this investigation were first acquired macroscopically. It was noted that several colony characteristics included colour, texture, border, and height. It was noted that B. subtilis had an entire border, a smooth texture, and a yellowish coloration. The isolates` biochemical examination reveals Bacillus subtilis, Pseudomonas sp., and pseudomonas aeruginosa. The fact that the bacteria are there indicates that the soil is a natural habitat for them. based on the biosurfactant activity screening using the oil spread, drop collapse, and haemolysis tests. Every isolate underwent a hemolysis test, and every one of them proved positive (Pseudomonas spp., however, had a negative result). The haemolysis result demonstrates beta hemolysis activity, a sign of the strain`s capacity to generate biosurfactants. With the exception of pseudomonas sp., all isolates showed positive for the drop collapse and oil spread tests. Further research is required to determine the precise features of the type and structure of the biosurfactant that these bacteria eat, based on the results of this study. &nbsp
