WebApr 15, 2024 · The degradation of phenol at different concentrations by three strains was investigated at low temperature [Fig. 1 (b)]. At the degradation of 100 mg L −1 phenol, the degradation rate of Ju-A4 was 100% in 20 h, with a maximum degradation rate of 8.53 mg h −1. The degradation rates of Ju-A1 and Ju-A6 were 48.5% and 42.4% at 20 h. WebPhenol is no exception - the only difference is the slow reaction because phenol is such a weak acid.

WebHanks' balanced salt solution (HBSS) Originally formulated in 1940 by microbiologist, John Hanks, HBSS is rich in bicarbonate ions. Ordinarily used as buffer systems in cell culture media, HBSS helps maintains optimum physiological pH. Because these buffers are low in reactivity, HBSS is often used in atmospheric conditions. Webunder different operating conditions; various phenol and salt concentrations were investigated. Results showed that doubling the anode’s surface area improved the performance of MDC in terms of voltage generation by 45%, phenol removal by 24%, and desalination rate by 9%. Our future work will study the suitability of microbial desalination ...
