“…However, different environmental parameters including temperature, pH, conductivity, and interfering electron acceptors could impact ORP at the cathode. 44,58,59 During colder months (October–February), the signal was only correlated with VFA, and since VFA did not significantly impact the total variance of the data with its negligible absolute eigenvalue, it was concluded that the signal's variance could not be linearly explained by any of the measured environmental parameters (Fig. 5C).…”

“…In cases where a BES was used for detection of acetate, strong linear relationships between current and acetate were reported. 44 While an MFC-based biosensor was successfully used for detection of acetate at concentrations 0.5–20 mM, 45 a low acetate detection limit of 5 μM was reported in a marine MFC biosensor. 46 However, in field conditions understanding the variations of total VFA is more insightful.…”

The present study involves the characterization and microalgal toxicity screening of diagnostic X-ray fixer solution toward utilization as a probable full-scale bioremediation study. The characterization results showed a BOD value of the waste X-ray fixer solution 11,833 ± 485.62 mg/l and 506,733 ± 251.66 ppm COD. The Scendesmus abundans was well grown using BBM, 1500 lx light intensity, 12 h:12 h light and dark conditions with 100 rpm shaking at 25 ± 1 °C on 1-month cultivation. The executed toxicity screening results of the diagnostic fixer solution on S. abundans with different dilutions have shown a promisable growth between 15 and 21 days with the 3 BBM:1 X-ray fixer solution dilution with a maximum cell count of 370 × 10 4 cells/ml on the 21st day of microalgal cultivation. The present study puts forth the physical and chemical parameters of X-ray fixer solution with proven toxicity tolerance limits of S. abundans toward the probable logical step of algal-based bioremediation of fixer solution.

“…The stability of the BOD biosensor was greatly affected by the immobilized method. Especially, the biodegradability of the microorganism that was immobilized on the BOD biosensor plays a critical role in the application scope of the water body [ 7 , 8 ]. Most of them choose a single strain, as they exhibit good performances for the standard solution.…”

In this study, we developed a simple strategy to prepare a biofilm reactor (BFR) sensor for the universal biochemical oxygen demand (BOD) determination. The microorganisms in fresh water were domesticated by artificial seawater with different salinity gradients successively to prepare the BFR sensor. The prepared BFR sensor exhibits an efficient ability to degrade a variety of organic substances. The linear range of BOD determination by the BFR sensor is 1.0–10.0 mg/L−1 with a correlation coefficient of 0.9951. The detection limit is 0.30 mg/L according to three times of signal-to-noise ratio. What is more, the BFR sensor displayed excellent performances for the BOD determination of different water samples, including both fresh water and seawater. The 16S-rRNA gene sequencing technology was used to analyze the microbial species before and after the domestication. The results show that it is a general approach for the rapid BOD determination in different water samples.
