The introductory passage discusses the importance of being able to study anme in a pure culture instead of in the consortium that exists in nature. Many bacteria exist in biofilms in nature. Based on the information in the passage and in the chapter, is it possible to create a pure culture of a species that normally exists in biofilms?.



Answer :

Yes, as a biofilm can include a single species and numerous species can have planktonic growth or reside there.

Plankton- Microalgae, sometimes referred to as phytoplankton, are comparable to photosynthetic organisms in that they have chlorophyll and need sunlight to survive and develop. The upper ocean, where sunlight may reach the water, is where the majority of phytoplankton floats since they are buoyant. The growth of plankton is known as Planktonic growth.

Biofilm- An extracellular polymeric material matrix surrounds an assembly of surface-associated microbial cells that is known as a biofilm. Van Leeuwenhoek is credited with discovering microbial biofilms because he discovered bacteria on tooth surfaces using his crude microscopes.
