We report the use of a simple yet highly effective magnetite-waste tea composite to remove lead(II) (Pb(2+)) ions from water. Magnetite-waste tea composites were dispersed in four different types of water-deionized (DI), artificial rainwater, artificial groundwater and artificial freshwater-that mimic actual environmental conditions. The water samples had varying initial concentrations (0.16-5....

Laccases have potential applications in industrial, biotechnological, and environmental set ups. Development of cost effective and efficient production technologies has gained significant attention in recent years. To enhance the laccase production from Rheinheimera sp. (Gram negative) using submerged fermentation (SmF) and from Lysinibacillus sp. (Gram positive) using solid-state fermentation ...

About 75% of the estimated 2.5 milliontons of dried tea harvested annually in the world is manufactured as black tea. Black tea (Camellia sinensis) is one of the most widely popular nonalcoholic beverages consumed by over two-thirds of the world's population, due to its medicinal, refreshing and mild stimulating effects; besides the positive effects, studies have also shown that drinking tea ca...

The variation in the composition of fresh tea leaves with season and shoot maturity, and to the applicability of cold storage (4C and 90% relative humidity [RH]) for the purpose of withering of tea leaves were studied. The results showed that the levels of polyphenol oxidase (PPO) activity and the polyphenolic content changed significantly with plucking season and shoot maturity. No significant...

Pollution of waterways is increasing geometrically on daily basis and this becoming a serious threat to human health, aquatic ecosystems aquaculture, these pollutions mostly include heavy metals. These metals pose danger due their high ability bio accumulation magnifications along the food chain. Thus, aim research work determine efficiency Tea Leaves Fibre as adsorbents in removal Cu2+ from aq...

Ascorbic acid (AsA), known as vitamin C, is an essential nutrient for humans and mainly absorbed from food. Tea plant (Camellia sinensis (L.) O. Kuntze) leaves can be a dietary source of AsA for humans. However, experimental evidence on the biosynthesis, recycling pathway and distribution of AsA during leaf development in tea plants is unclear. To gain insight into the mechanism and distributio...
