Question

What advantage does a metagenomics approach have over a culture-dependent approach when trying to determine the bacterial density in a complex environmental sample?

List 4 environmental properties that can have a significant impact on the growth of a bacterial species. List 3 environmental conditions that might trigger endospore formation?

Please provide written answer for the questions. Thank you

Answer 1

The primary advantage of culture-independent methods is their capacity to promptly distinguish an enormous extent of the bacterial assorted variety that can be hard to watch with culture-based studies. Metagenomics will be the frameworks science of the biosphere. Metagenomics provides a means for studying microbial communities on their own turf. Complex biological collaborations—including lateral gene exchange, phage-host dynamics, and metabolic complementation.

Endospore formation is usually triggered by a lack of nutrients, desiccation, environmental stress like ultraviolet and gamma radiation, temperature and starvation.
