- Abstract:
- ... Objective: Chlorella vulgaris is a popular food supplement in Asia and is currently marketed as a nutritional supplement. However, available scientific studies do not support its effectiveness for preventing or treating any disease in humans. Because Chlorella contains numerous nutrients, including antioxidants, it is thought to exert antioxidative functions by scavenging free radicals created by ...

A concentration-dependent increase in activity of antioxidant enzymes (catalase, ascorbate peroxidase, glutathione reductase, ssuperoxide dismutase) and the level of total ascorbate and reduced glutathione have been observed in the green alga Chlorella vulgaris following heavy metals exposure. It was arranged in the following order: copper>lead>cadmium. It was also found that brassinolide activate ...

Algicidal bacteria have been turned out to be available for inhibiting Phaeocystis globosa which frequently caused harmful algal blooms and threatened to economic development and ecological balance. A marine bacterium Bacillus sp. Ts-12 exhibited significant algicidal activity against P. globosa by indirect attack. In present study, an algicidal compound was isolated by silica gel column, Sephadex ...

Several techniques using antibiotics, ozone, chemical compounds, algae, and probiotics, have been tested to reduce bacterial load in Artemia. This research looked at the potential of salt to reduce bacterial contamination ...

Impact of ascorbate biosynthetic inhibitor (lycorine, LYC) on short-term cadmium (Cd) action (1h, 100μM) was studied in the green alga Scenedesmus quadricauda with 1h or 24h of LYC co-application. LYC suppressed Cd-induced increase in ascorbic acid and enhanced oxidative symptoms (ROS fluorescence) by modulating activities of antioxidative enzymes after 24h of addition (decrease in superoxide dism ...
