The Investigation Of Several Microorganisms Isolated From Fermented Food Waste And Its Possibility For Treating Contaminated Water In Malaysia

---

Malaysia faces water and food waste issues. Majority of wastewater in Malaysia contains ammonium and
phosphate, which is dangerous towards health and environment. In Malaysia, the food waste mainly
consists of fruit and vegetable waste. Nowadays, as the world progresses towards sustainable
development, food waste valorisation is implemented to solve the wastewater issue. This study aims to
characterize the various microorganisms found in fermented food waste, specifically focusing on their
capacity to remediate wastewater contaminated with ammonium and phosphate. The food waste
underwent fermentation, and the cultured bacteria were analyzed for characterization through gram
staining and selective agar, MYP, M17, MRS and XLD, respectively. The gram staining result signifies that
the fermented food waste samples are mixed cultures which contain various types of bacteria. The
findings indicate that group A from the sample significantly reduced the concentrations of
ammonia/ammonium in the wastewater from 14 ppm to 0.9 ppm. The pH of synthetic wastewater
successfully decreased from 8.5 to 7.54. However, all of the samples showed limited efficacy in
decreasing phosphate concentration. As for the future recommendations, biological replicates should be
involved, conducting genomic testing/sequencing to know the specific bacterial strains within the mixed
culture responsible for effective wastewater treatment.
