“…Temperature affected the physicochemical parameters of sludge samples, so it is considered as a key factor in shaping the structures of microbial populations. High records of microbial loads of S3 sample are harmonious with the results of Madni et al [35] who reported that high temperature favors the survival of microorganisms. The global energy crisis and the limited resources necessitates the search for alternative sustainable energy sources.…”

Microbial fuel cell (MFC) is a bio-electrical energy generator that uses respiring microbes to transform organic matter present in sludge into electrical energy. The primary goal of this work was to introduce a new approach to the green electricity generation technology. In this context a total of 6 bacterial isolates were recovered from sludge samples collected from El-Sheikh Zayed water purification plant, Egypt, and screened for their electrogenic potential. The most promising isolates were identified according to 16S rRNA sequencing as Escherichia coli and Enterobacter cloacae, promising results were achieved on using them in consortium at optimized values of pH (7.5), temperature (30°C) and substrate (glucose/pyruvate 1%). Low level red laser (λ = 632.8nm, 8mW) was utilized to promote the electrogenic efficiency of the bacterial consortium, maximum growth was attained at 210 sec exposure interval. In an application of adding standard inoculum (107 cfu/mL) of the photo-stimulated bacterial consortium to sludge based MFC a significant increase in the output potential difference values were recorded, the electricity generation was maintained by regular supply of external substrate. These results demonstrate the future development of the dual role of MFCs in renewable energy production and sludge recycling.

“…Similar results observed in Nigeria that the microbial load after 24 hours and 48 hours of incubation, with the values 1.8×10 5 CFU/ml and 2.6×10 5 CFU/ml respectively, which is also higher than the recommended value (Sunday et al, 2014). Additionally, Madni et al (2022) found the microbial load 6.5×10 3 to 8.9 × 10 5 during winter and 5.5×10 3 to 7.3×10 5 during summer season in Swakin city, Sudan. According to guideline of WHO (1996), TVC value should be 1×10 3 CFU/ml.…”

Drinking water (DW) from restaurants is a major source of microbial exposure among consumers that causes diseases. The evaluation of the microbiological quality of the drinking water in restaurants provides the foundation for appropriate action to minimize contamination and protect patrons from food-borne illnesses. The aim of this study was to determine the microbial quality of restaurant’s drinking water. A total of 20 water samples were collected in sterile test tube from the restaurants in Dumki and Patuakhali Sadar Upazilla of Patuakhali district. Total viable count on Nutrient agar and total coliform count on MacConkey agar were done by standard plate count (SPC) technique and bacterial identification by different biochemical tests. The present study found all the water samples (100%) were contaminated with bacteria in the ranges of 4.50 × 104 to 7.00 x 105, and 95% of the samples were contaminated with E. coli, and the range was 0 to 2.8 × 102. A total of 26 distinct bacterial colony were isolated from various samples and morphologically characterized. Based on biochemical characteristics, we identified a total of 10 bacterial species. Among them, 6 (23.10%) were both for Enterobacter aerogenes and Staphylococcus epidermidis followed by Escherichia coli (E. coli) 5 (19.23%), Pseudomonas spp. 3(11.54%), and rest of the Vibrio cholera, Klebsiella oxytoca, S. auerous, Bacillus spp., Aeromonas salmonicida and Salmonella spp. were 1 (3.85%) for each. A diverse range of fecal coliform, enteropathogenic and pathogenic bacteria present in samples indicates the unsanitary handling and storage practices in restaurants; this could make customers more susceptible to illnesses and ailments linked to water.
