ABSTRACT
This study investigates the efficiency of different bacteria compositions in degrading food waste. This study focuses on the three food types: gummy bears, rice, and chicken breast. The bacteria sources used in the study were from three different sources: a commercial food-degrading mix, earthworm feces, and yogurt. The result showed that yogurt-derive bacteria, rich in Lactobacillus bacteria, were most effective in degrading carbohydrate-based foods on gummy bears and rice. However, it was ineffective for protein-rich foods like chicken breast. However, combining food-degrading bacteria and earthworm feces was most efficient for chicken breast degradation. This study also performed the 16S rRNA sequencing and identified the key bacterial strains: Lactobacillus paracasei (food-degrading bacteria), Rhizobium leguminosarum (earthworm feces), and Lactobacillus delbrueckii (yogurt). This study showed the importance of selecting bacterial strains based on the type of food waste for optimizing the biodegradation process. Overall, this study suggests an efficient way to solve the problem of food waste with bacteria degradation.
