Overview of wastewater treatment methods with special focus on biopolymer chitin-chitosan.

Heavy metals have substantively high values of half-lives with nonbiodegradable chemical nature. At the same time, their ionic compounds have amazing ability of ionization in aqueous media. Remediation of such metals from wastewaters has been very complex, expensive and a challenging goal for ages.

Endophyte-induced Verticillium protection in tomato is range-restricted.

Endophytes, bacterial, fungal or viral, colonize plants often without causing visible symptoms. More important, they may benefit host plants in many ways, most notably by preventing diseases caused by normally virulent pathogens. Previous studies have shown that an isolate of V.
