Article Synopsis
- - The study isolated a new bacterial strain, Staphylococcus petrasii sub sp. jettensis (VSJK R1), which efficiently degrades fats, oils, and grease (FOG) pollutants commonly found in wastewater from sources like restaurants and kitchens.
- - Optimal biodegradation conditions were identified, including the use of organic nitrogen sources, glucose, neutral pH, and specific temperature ranges (22°C to 45°C), leading to significantly improved degradation rates.
- - Comparisons to other microbial strains highlighted the exceptional ability of VSJK R1 to break down various edible oils, suggesting its potential for bioremediation in wastewater treatment facilities and grease traps.
Article Synopsis
- The study investigated the effects of photosynthetically active radiation (PAR) and ultraviolet (UV) radiation on the cyanobacterium Anabaenopsis circularis HKAR-22, focusing on growth, chlorophyll a content, and photosynthetic performance.
- The presence of the UV-screening molecule shinorine (SN) was confirmed using various analytical techniques, with notable absorption characteristics identified.
- SN demonstrated strong antioxidant properties through several assays, and quantum chemical calculations suggested its potential application in cosmeceutical products.
Ultraviolet radiation (UVR) tends to damage key cellular machinery. Cells may adapt by developing several defence mechanisms as a response to such damage; otherwise, their destiny is cell death. Since cyanobacteria are primary biotic components and also important biomass producers, any drastic effects caused by UVR may imbalance the entire ecosystem.

The edible oil in such wastewater harms the environment in a number of ways. The native bacteria in the wastewater are less effective in degrading edible oil.
