Plant-Based Natural Bioactive Compounds 2,4-Ditert-Butylphenolas: A Potential Candidates Against SARS-Cov-2019.

The novel coronavirus 2019 is spreading around the world and causing serious concern. However, there is limited information about novel coronavirus that hinders the design of effective drug. Bioactive compounds are rich source of chemo preventive ingredients.

Exogenous production of cold-active cellulase from polar Nocardiopsis sp. with increased cellulose hydrolysis efficiency.

The present work was designed to isolate and characterise the actinobacteria in the Polar Front region of the Southern Ocean waters and species of Nocardiopsis and Streptomyces were identified. Among those, the psychrophilic actinobacterium, Nocardiopsis dassonvillei PSY13 was found to have good cellulolytic activity and it was further studied for the production and characterisation of cold-active cellulase enzyme. The latter was found to have a specific activity of 6.

Fabrication of poly (methyl methacrylate)/Ce/Cu substituted apatite/Egg white (Ovalbumin) biocomposite owning adjustable properties: Towards bone tissue rejuvenation.

A new biocomposite including Poly (methyl methacrylate)/Ce-Cu substituted apatite/Egg white (Ovalbumin) (PMMA/MHAP/EW) has been effectively manufactured via lyophilization technique. The reason to plan such biocomposite is to investigate for a perfect simple which may bio-imitate the constitution of natural bone for hard tissue designing regarding appropriate biodegradability, biocompatibility, and bactericidal properties. The FTIR and XRD spectra of prepared biocomposite showed the considerable intermolecular interface between the different constituents of the biocomposites.
