Abstract
Serratia and Pseudomonas strains in soil add to the large
microbiome of its environment. Serratia and Pseudomonas in
particular can contribute to their environment by purifying and
cleaning toxins out of the soil they live in. In this experiment,
a few types of bacteria were isolated from soil in one local
location. The purpose of this research was to find if there was
detectable diversity among the isolated species from this soil
extraction. We hypothesized that even amongst samples taken
of the same species, there would be some detectable diversity.
One phenotype for measuring diversity is biofilm formation.
The formation of a biofilm makes these strains of Serratia
more virulent. A biofilm is a structured community of bacteria
in a self-produced matrix. Swarming is a form of bacterial
surface translocation that aims at colonizing all available
surface space as quickly as possible. Swarming has been
found to cause overexpression of virulence related genes,
especially those of the type III secretion system. Products of
this system often have cytotoxic effects. The gene that
produces the most powerful cytogenetic effects is exoU.
Diversity and variances can be found in any of these
properties and abilities of these bacteria, such as biofilm
formation, antibiotic resistance, and more.
