Abstract
Probiotics are microorganisms residing in the gastrointestinal tract
that have been shown to help with metabolic functions, immune
responses, and in the prevention of pathogenic diseases. In this
study, we sought to determine if the probiotic brand, Garden of Life,
could acquire novel phenotypes through heat-shock transformation.
We predicted that Garden of Life, along with Escherichia coli
HB101 and Escherichia coli B would be able to grow on ampicillin
enriched plates after transformation with the plasmid, pGLO, which
contained the gene for beta-lactamase. During the study, all
three bacterial cultures underwent heat shock transformation in the
presence of pGLO. After transformation was complete, each new
culture was plated on LB agar containing ampicillin and arabinose
to determine whether antibiotic resistance and GFP expression were
observed. The results showed that only Escherichia coli HB101 had
successfully become antibiotic resistant. Our results demonstrate that
the gram positive species in Garden of Life probiotics are not able to
efficiently take up plasmid DNA using heat shock transformation and
that the method appeared to have strain restrictions as well.
