Abstract
Widespread antibiotic use has led to antibiotic resistance of infectious bacteria. (Young, 2017) As part of the TinyEarth Program, the lab group collected and tested local soil samples for bacteria with hopes of finding novel antibiotic properties. From the soil samples, a bacteria was isolated, subsequently sequenced, and determined to be Pseudomonas parafulva. P. parafulva is a Gram-negative bacterium that has been known to frequent rice paddies of eastern Asian countries and has been collected in select regions of North America, including that of Cache Valley. P. parafulva has been linked to anti-fungal activities on plants. (Lui et al, 2015) Botrytis cinerea is a common plant fungi that affects more than 1400 plant species and is responsible for 10-100 billion USD of annual losses due to worldwide crop damage. (Roca-Couso R et al, 2021) We hypothesized that P. parafulva will show measurable zones of inhibition against B. cinerea when placed in the same environment. In rice fields in Asia, P. parafulva has been shown to be antagonistic to several prevalent fungi, but not including B. cinerea (Qunen et al, 2015). Due to the nature of P. parafulva against these fungi, we predict that it will show antagonistic characteristics to B. cinerea.
