“…However, despite these slight differences, the biosensor based on an immobilized mixture of yeast cells in an organosilicate shell showed promise as a tool for monitoring pollution in surface waters. The correlation with the standard method for a biosensor based on a group of microorganisms immobilized in the developed sol–gel matrix was R 2 = 0.9992, which is higher than that for previously described analogues. , Importantly, the analysis using the developed heterogeneous biocatalyst required only 10–15 min compared to the 5-day duration of the standard BOD determination method.…”

This study presents a novel ″3-in-1″ hybrid biocatalyst design that combines the individual efficiency of microorganisms while avoiding negative interactions between them. Yeast cells of Ogataea polymorpha VKM Y-2559, Blastobotrys adeninivorans VKM Y-2677, and Debaryomyces hansenii VKM Y-2482 were immobilized in an organosilicon material by using the sol–gel method, resulting in a hybrid biocatalyst. The catalytic activity of the immobilized microorganism mixture was evaluated by employing it as the bioreceptor element of a biosensor. Optical and scanning electron microscopies were used to examine the morphology of the biohybrid material. Elemental distribution analysis confirmed the encapsulation of yeast cells in a matrix composed of methyltriethoxysilane (MTES) and tetraethoxysilane (TEOS) (85 and 15 vol %, respectively). The resulting heterogeneous biocatalyst exhibited excellent performance in determining the biochemical oxygen demand (BOD) index in real surface water samples, with a sensitivity coefficient of 50 ± 3 × 10–3·min–1, a concentration range of 0.3–31 mg/L, long-term stability for 25 days, and a relative standard deviation of 3.8%. These findings demonstrate the potential of the developed hybrid biocatalyst for effective pollution monitoring and wastewater treatment applications.

“…Collected water samples were transported to the laboratory at 4°C for subsequent laboratory analysis. Chemical Oxygen Demand (COD) and ammoniacal nitrogen testing were performed using a DR 2800 spectrophotometer (HACH, 2007), while Biochemical Oxygen Demand 5 (BOD5) was measured using a BOD probe (Verma & Singh, 2013). Total suspended solids (TSS) were quantified using a standard method (American Public Health Association, 2012).…”

This study aimed to evaluate benthic macroinvertebrates assemblages using the application of ecological indices in the Rawang sub-basin of the Selangor River with reference to determining the impacts of aquaculture practices on benthic macroinvertebrates. In total, seven sampling sites were selected, namely Guntong (SR1), Guntong’s tributaries (SR2, control site), Kuang (SR3 and SR7), Gong (SR4), Buaya (SR5) and Serendah (SR6) Rivers. Sites were selected using a random sampling technique and the accessibility and proximity to aquaculture farms. Macroinvertebrates were sampled from April 2019 to March 2020 using an aquatic kick net, a hand spade, and a D-frame dip net. Water samples were also taken. Twenty-seven families belonging to the Annelida, Mollusca and Athropoda phyla were identified using taxonomic keys. Tubificidae was found to be the most dominant family (36.79%) followed by Chironomidae (28.84%). The highest number of individuals from family Tubificidae was recorded in Gong River, where effluent was discharged from an aquaculture farm. The total abundance of benthic macroinvertebrates increased with increased proximity to the aquaculture farm. Based on Biological Monitoring Working Party score value, the water quality of sampling sites in close proximity to the aquaculture farm was polluted as compared to the control location. Family Biotic Index score showed that all sites were substantially polluted with organic pollution, with the control site being much less polluted. In conclusion, benthic macroinvertebrates assemblage was affected by effluent originating from aquaculture farm outlets. It is therefore necessary to conduct aquaculture farming using methods that are deemed to be environmentally friendly.

“…Dissolved oxygen is one of the most important parameter in water quality assessment and reflects the biological and physical process prevailing in the water [12]. In this study, the dissolved oxygen (DO) levels vary from 2.52 -5.87 mg/L.…”

Adequate water resources for future generations are not only a regional issue but also a global concern. Our country's fresh water wealth is under threat due to variety of natural and human influences, so there was a need to test the water qualities. The water quality assessment was conducted under Mokokchung District, Nagaland. The samples collected were analyzed for various parameters -pH, TDS, EC, TH, DO, BOD, ORP, SULFATE, PHOSPHATE, CALCIUM, MAGNESIUM, CHLORIDE, ALKALINITY and IRON. It has been observed that most of the water samples were within the permissible limits of the given standards.
