“…The isolated photosynthetic bacteria were characterized on the basis of colony, morphology, colour, growth characteristics, Gram staining, mobility, catalase, oxidase, urease, nitrate reduction and carbohydrate utilization tests (Table 5 and 6). The use of morphological, physiological and biochemical test for the identification of the isolate were adopted from the research of [14]. In his research he confirmed that all the isolates produced yellow-brown to yellow-green cultures under anaerobic phototrophic growth conditions.…”

Wastewater is untreated water that has high amount of nutrients such as nitrate, phosphate, ammonium and chemical oxygen demand (COD). When it is discharged into watercourse, it affects human and aquatic biota. The application of photosynthetic bacteria is considered bio-friendly system than the conventional one. Hence, the present study investigates the effectiveness of robust strain of photosynthetic bacteria for nitrate removal under different concentrations of 85, 135, 190, 235 and 320 mg/L. Serial dilution techniques was used for the isolation of the bacteria. The results showed that three bacterial isolate were obtained and were both screened for nitrate reduction ability. The isolate was able to remove 91, 90, 71, 67 and 55% of nitrate at 85, 135, 190, 235 and 320 mg/L respectively. The bacteriochlorophyll of the isolate was detected at peak range between 689-710 nm. The morphological, physiological and biochemical characterization showed that the isolate was identified as Rhodopseudomonas sp. The nutrient removal yield of the nitrate under different concentrations was found to be at range of 0.01- 0.033 g-1 DCW g-1 NO3.- This study suggested that the strain could be used as an efficient bacterial candidate for the treatment of wastewater containing high amount of nitrate.

Well-adapted bacteria under wide extreme conditions of acidic/alkaline pH and hot/cold temperatures play a significant role in degradation efficiency and in eliminating the cost of waste treatment processes in large areas. Extremozymes isolated by these organisms are resistant to extraordinary properties of salt allowance, cold adaptivity, and thermostability. In this study, we aimed to assess the isolation of protease-, amylase-, cellulase-, and lignin peroxidase-producing bacteria using a wide range of physical parameters to select suitable isolates and investigate their functions and enzyme activities. The bacterial strain FW2 was isolated from food waste and screened the growth and the degradation of organic compounds under fluctuating temperatures, different pH values, and high salinity concentrations. This strain was able to degrade organic compounds at temperatures from –6℃ to 75°C (weak at 80°C) under a wide pH range of 4.5–12, and in a sodium chloride (NaCl) concentration of 0–35%. Maximum enzyme production was obtained at 1200 U/mL for protease, 2400 U mL-1 for amylase, 920 U/mL for CMCase, 1300 U/mL for Avicelase, and 0.165 U/mL for Lignin peroxidase at pH 7–7.5, 40–45°C, and 0–10% NaCl. With these valuable characteristics, strain FW2 may be a potential contributor to waste degradation under fluctuating environmental conditions.
