Article Synopsis
- Effluents from textile industries pose significant environmental challenges, leading to this study focusing on 23 bacterial strains isolated from dye wastewater.
- A novel strain, Enterobacter aerogenes ES014, effectively decolorized three azo dyes—acid orange, methyl orange, and congo red—under optimized conditions, demonstrating a high potential for environmental remediation.
- The strain not only improved wastewater quality by reducing harmful compounds but also enhanced seed germination and brine shrimp survival, indicating its effectiveness for treating textile effluents and mitigating toxicity.
Biofilm producing indigenous bacteria isolated from municipal sludge and their nutrient removal ability in moving bed biofilm reactor from the wastewater.
Saudi J Biol Sci
September 2021
In the present study, improved moving bed biofilm reactor (MBBR) was applied to enhance the nutrient removal ability of the municipal wastewater. A total of 18 indigenous bacterial isolates were screened from the sewage sludge sample and nitrate reductase, nitrite reductase and hydroxylamine oxidase was analyzed. The strains NU1 and Acinetobacter calcoaceticus K12 produced 0.

- The study focused on identifying bacteria that produce biofilms in dental caries, highlighting the strain DC-17, which showed strong biofilm-forming abilities and antibiotic resistance.
- DC-17 synthesized a significant amount of extracellular polymeric substances (EPS), primarily made up of proteins (1.928 mg/mL), carbohydrates (162.3 mg/L), and DNA (4.95 µg/mL), which are essential for biofilm structure and function.
- Factors like temperature, pH, and sugar concentration affected biofilm production, with optimal conditions found at alkaline pH, 40°C, and 8% sucrose, while the biofilm formed was notably resistant to various antibiotics, particularly pen
Gibberellic acid from the fungi has been widely used in agriculture. In this study, more than 20 fungal isolates were screened and sp. ZB shown to produce more gibberellic acid than other fungal isolates.
