Biosorbents for hexavalent chromium elimination from industrial and municipal effluents

Fermentation of sugared tea with a symbiotic culture of acetic acid bacteria and yeast (tea fungus) yields kombucha tea which is consumed worldwide for its refreshing and beneficial properties on human health. Important progress has been made in the past decade concerning research findings on kombucha tea and reports claiming that drinking kombucha can prevent various types of cancer and cardiovascular diseases, promote liver functions, and stimulate the immune system. Considering the widespread reports on kombucha, we recognized the need to review and update the research conducted in relation to kombucha tea, its products and tea fungus. Existing reports have suggested that the protective effects of kombucha tea are as good as those of black tea, however, more studies on kombucha tea and its composition are needed before final conclusions can be made.

A review on kombucha tea - microbiology, composition, fermentation, beneficial effects, toxicity, and tea fungus.

Water is the most important and essential component of earth's ecosystem, playing a vital role in the proper functioning of flora and fauna. But water resources are contaminating continuously. The whole world may be in great water scarcity in the coming few decades. Among many water treatment methods, adsorption is considered to be one of the best. Many articles describe adsorption applications for water treatment in batch mode. Only few works report laboratory, pilot and commercial applications of adsorption technology. This review is a critical evaluation of the contribution of adsorption technology at laboratory, pilot and process scales. Water treatment, through column operations, has been divided into two parts: removal of (i) inorganic and (ii) organic pollutants. Attempts have been made to evaluate the application of adsorption columns at the ground level. Besides, efforts have also been made to emphasize the importance of adsorption columns at commercial levels to tackle water treatment problems i...

Sorption of Cr(VI) from dilute solutions and wastewater by live and pretreated biomass of Aspergillus flavus

Kombucha tea (KT) is sugared black tea fermented with a symbiotic culture of acetic acid bacteria and yeasts, which is said to be tea fungus. KT is claimed to have various beneficial effects on human health, but there is very little scientific evidence available in the literature. In the present study, KT along with black tea (BT) and black tea manufactured with tea fungus enzymes (enzyme-processed tea, ET) was evaluated for hepatoprotective and curative properties against CCl4-induced toxicity, using male albino rats as an experimental model by analyzing aspartate transaminase, alanine transaminase, and alkaline phosphatase in plasma and malondialdehyde content in plasma and liver tissues. Histopathological analysis of liver tissue was also included. Results showed that BT, ET, and KT have the potential to revert the CCl4-induced hepatotoxicity. Among the three types of teas tried, KT was found to be more efficient than BT and ET. Antioxidant molecules produced during the fermentation period could be the reason for the efficient hepatoprotective and curative properties of KT against CCI4-induced hepatotoxicity.
