A Review: A Source of Industrially Important Enzymes from Marine Actinomycetes
Abstract: Actinomycetes are Gram-positive, spore-forming, filamentous actinobacteria which usually contain G+C content of about 57–75% in their DNA. Actinomycetes are considered as a unique group of a microorganism having the characters of the true bacteria and the true fungi. Actinomycetes that have been detected from extreme conditions are considered to be sources of new enzymes of great industrial potential. They produce valuable secondary metabolites and industrially significant enzymes like pectinase, amylase, …

Determination of A More Efficient Method of Grafting Mangoes and Optimum Growth Environment for A Successful Graft Union
Abstract: AbstractMangoes (Mangifera indica) have traditionally been propagated through seeds but this process takes many years for trees to start bearing fruits (7–10 years). Grafting is used to shorten the juvenile period in which mangoes start bearing between as early as 1 to 3 years. Farmers believe that after grafting, grafted plants need to be placed in greenhouse for successful union of the graft and growth of the sprouts. Authors know …

An Approach to Treat Corvid-19: An Opinion to Use Angiotensin Converting and 4-Dipeptidyl Peptidase Enzymes Inhibitors
Abstract: Abstract Coronavirus (CoV) attach the cell surface and enter the host cell via interaction with angiotensin converting enzyme receptor. Viral replication induces dysregulation of the autophagy process and interferes with the natural function of the lysosomes. Antimalarial drugs, including chloroquine and hydroxychloroquine through their lysosomotropic and autophagy inhibiting effects may be useful in the management of CoV infections. Among the people who at risk of developing CoV infections are hypertensive …
