Which of the species are likely to grow in a jar of canned tomatoes (canned tomatoes are quite acidic)?
The species that are most likely to grow in a jar of canned tomatoes based on our lab would be S. cerevisiae because they thrive under a low ph compared to all the other species.
Based on your results, do you consider that bacteria are more acid tolerant than fungi? Explain the reason for the choice you have made.
