“…A quantitative assay for biofilm formation of bacterial isolates was performed in sterile polystyrene 96-well flat-bottom microtiter plates in triplicates, following the protocol described by Rao TS, 2022. [14] Autoclaved L-broth without Cu +2 stress was added to two rows of microtiter plates (180 µl/well), and L-broth with Cu +2 stress was added to the other two rows. A 20 μl inoculum of bacterial culture (OD600nm= 0.1) was added to all wells, except control wells.…”

This research aimed to isolate copper-resistant bacteria from industrial effluents for potential bioremediation in both planktonic and biofilm growth modes. Out of ten isolates from industrial effluents, four bacterial strains (S1A, S2C, SSA, and S1C) wereselected based on their minimum inhibitory concentration (MIC) and biofilm-forming capabilities. These bacteria demonstrated strong biofilm formation abilities in both the absence and presence of copper (Cu) stress, with MIC values of 850 μg/ml for S1A, SSA, and S1C, and 750 μg/ml for S2C. Physiological characterization revealed that these isolates exhibited optimal growth at pH 7 and 37°C. Biochemical characterization indicated the similarity of these copper-resistant bacteria with the genera Staphylococcus (S1C), Bacillus (SSA), Corynebacterium (S1A), and Enterobacter (S2C). The copper removal efficiency of these isolates was assessed in both planktonic and biofilm growth modes using atomic absorption spectroscopy. In planktonic growth, all isolates showed copper removal efficiencies of 81.4% (S1A), 81% (SSA), 83.5% (S2C), and 82.3% (S1C) after 24 hours, and 84% (S1A), 83.4% (SSA), 85.3% (S2C), and 84.2% (S1C) after 48 hours. Notably, in planktonic growth, S2C (Staphylococcus) exhibited the highest removalefficiency, with 83.5% and 85.3% after 24 and 48 hours, respectively. In the biofilm growth mode, copper removal efficiencies were 84.2% (S1A), 82.7% (SSA), 81.9% (S2C), and 84% (S1C) after 24 hours, and 86.7% (S1A), 86.1% (SSA), 85.6% (S2C), and 86.2% (S1C) after 48 hours. Notably, S1A (Corynebacterium) displayed the highest copper removal efficiency, with 84.2% and 86.7% after 24-and 48-hour incubation in biofilm growth modes.KEYWORDSAtomic absorption spectrophotometer, Biofilms, Bioremediation, Minimum inhibitory concentration.

“…The problem of efficient cooling of recirculated water in the CTs in today's conditions requires a complex approach that combines technical, economic, and environmental aspects. The fact is that warm water and the presence of air are a favorable environment for the growth of aerobic microorganisms, fouling layers appear on the heat exchange surface, which sharply reduces the cooling efficiency of thermal equipment [1,2]. There are several methods of biofouling control technology: the use of chemicals, bio-filtration and frequent maintenance, which leads to increased economic costs for enterprises [3][4][5].…”

A hybrid system for recirculated water cooling of industrial enterprises is proposed. The major feature of the cooling system is a wet/dry cooling tower with an inner pipe exchanger. To enhance the heat transfer process, the outer surface of the heat exchanger pipe has fins. Design and function of the experimental setup are described. The goal of this work is to evaluate experimentally the heat power of the wet and pipe sections of the cooling tower. Results were presented as dependencies of the heat power in the wet/dry cooling tower on the mean gas velocity (from 0.89 to 3.20 m/s) and the ratio of the weight flow rates of the gas/liquid phases at various irrigation rates (13.7-35.6 m3/(m2.h)).
