Flavonoid Contents and Antioxidant Activity of an Endophytic Bacteria Associated with Medicinal Plant Humulus lupulus
Abstract: Endophytes are symbiotic microorganisms, most often bacteria or fungi, that reside and multiply within plant tissues without inducing visible signs of disease or negatively affecting the host plant. Endophytic bacteria contribute to plant development by stimulating growth, strengthening defence mechanisms, enhancing tolerance to both abiotic and biotic stresses, and facilitating improved nutrient uptake. Endophytic bacteria serve as an important reservoir of bioactive compounds, notably antioxidant molecules, that play a crucial …

Optimization of Microbial Cellulose Production by the Newly Isolated Acetobacter sp. DR-1 under Laboratory Conditions
Abstract: Cellulose is the most abundant natural biopolymer on the earth, synthesized by plants, algae and also some species of bacteria. It is also produced by some animals (e.g., tunicates).Cellulose constitutes one of the three principal components present in plant, namely cellulose, hemi-cellulose and lignin. However, the degree of polymerization and crystallinity of bacterial cellulose is considerable high than that of plant cellulose. In microbes, cellulose is normally produced as exo-polysaccharide, …

Isolation of Lactobacilli sp. from Various Nondiary Substrates—A Review
Abstract: Lactic acid bacteria (LAB) have also been delineated as bioprotective agents. Efficient pathogens’ inhibition has been derived by LAB. LAB competes with the microbes by modifying the microenvironment with their metabolic end products. The habitat of Lactobacilli is not only confined to diary but it has spread and adapted habitat to nondiary substrates too. This paper garners information about the various nonsubstrate habitats in which Lactobacilli can be isolated. Keywords: …

Microbial Population Dynamics during Phytobioremediation of Hydrocarbon- Contaminated Swampy and Clay Soils
Abstract: Soil contamination by petroleum hydrocarbons remains a critical environmental challenge, particularly in wetland and clay-rich ecosystems where natural attenuation processes are often limited. This study investigates the response of total heterotrophic bacteria (THB) during the bioremediation of hydrocarbon-contaminated swampy and clay soils amended with Moringa oleifera biomass and elephant grass (Pennisetum purpureum). The objective was to evaluate microbial population dynamics under varying amendment dosages and to identify treatment conditions favorable …
