The mouth is a diverse ecosphere that houses a huge range of microorganisms such as fungi,
viruses and bacteria. Oral cavity consists of a variety of habitats, each with its own intrinsic,
particular mini-environment, such as tonsils, hard and soft palates, tongue, cheeks, and gingival
sulcus. Plaque biofilms on dental surfaces and planktonic phase organisms floating in saliva
are also examples of oral microbiome organisms. The majority of oral bacteria have not yet
been cultured; however, culture-independent techniques have been effective in providing a
through description of the mouth bacterial ecology. The dental flora is constantly altering
because its interaction with the surroundings and produces bacteriocins and competes for
nutrients within this tiny ecosystem. The objective of the current research was to evaluate and
contrast the microbial flora of both healthy and unhealthy people. In this study, the isolation
and identification of bacteriocin-producing bacteria was carried out. The samples were
collected from Parul University Master's students in Vadodara, Gujarat, India. The bacteria were extracted and identified using microscopy, gram staining, and biochemical analysis. The
study resulted in the isolation of 5 different bacterial strains, of which 2 were gram negative,
whereas three were gram positive. The very dominant species belonged to the Streptococcus
and Escherichia species as revealed according to Gram staining and biochemical tests. Many
other bacteria were also isolated such as Staphylococcus, enterococcus, Bacillus subtilis
family etc. It was found that the Enterobacter and Lactobacillus species produced bacteriocin
against Escherichia coli. Some of these microbes have been connected to the emergence of
multiple infectious illnesses.
