Autor: Rania M. M. Abdel-Baki, Marwa N. Ahmed, Olfat S. Barakat, Galal M. Khalafalla

Publikováno v: BMC Biotechnology, Vol 24, Iss 1, Pp 1-12 (2024)

Abstract Background Vitamin B12 is a crucial B-group vitamin, first isolated from the liver due to its role in combating pernicious anemia. It is distinguished by its unique and complex structure, which makes its chemical synthesis challenging and ex

Genetic characterization of a novel Salinicola salarius isolate applied for the bioconversion of agro-industrial wastes into polyhydroxybutyrate

Autor: Shymaa A. Abdelrahman, Olfat S. Barakat, Marwa N. Ahmed

Publikováno v: Microbial Cell Factories, Vol 23, Iss 1, Pp 1-17 (2024)

Abstract Background Polyhydroxybutyrate (PHB) has emerged as a promising eco-friendly alternative to traditional petrochemical-based plastics. In the present study, we isolated and characterized a new strain of Salinicola salarius, a halophilic bacte
