Diversity in bacteria | BACTERIA AND VIRUSES | Chapter 2| F.Sc. 1st Year Biology | L# 7

Dive into Chapter 2 of F.Sc. 1st Year Biology, covering the fascinating world of Bacteria and Viruses. This video is a complete lecture focusing on the diverse roles of key bacterial groups. We explore the Ecologic role of bacteria like Pseudomonas and Actinomycetes, including their function in denitrification and nitrogen fixation. Learn about important pathogenic bacteria such as Pseudomonas aeruginosa (causing serious infections), Mycobacterium leprae (leprosy), and Mycobacterium tuberculosis (TB). Crucially, discover the significance of Actinomycetes as a major antibiotic source (Tetracycline, Neomycin, Erythromycin). Finally, understand the vital function of Nitrogen-fixing aerobic bacteria (like Azotobacter) and Chemosynthetic bacteria (like Nitrosomonas and Nitrobacter) in the nitrogen cycle. Perfect for FSc students preparing for exams or seeking a deep understanding of microbiology basics!
