MICROBIOLOGY FOR STUDENTS (M4S): Basics of Bacterial Structure

Microbiology For Students (M4S) is an educational platform dedicated to the dissemination of microbiological knowledge to students at various academic levels. It aims to enhance understanding, stimulate intellectual curiosity, and support the academic development of individuals pursuing studies in microbiology, biology, biotechnology, and related disciplines.
