Abstract:
The food wastage due to household and industrial processes is estimated to be hundreds of tons representing environmental and economic issues. Lactic acid bacteria (LAB) led biorefinery processes of industrial interest are considered sustainable valorization techniques for nutrient-rich food organic waste. However, this food waste can be a major dissemination channel for transmitting antibiotic resistance (ABR) from non-pathogenic strains to the consumer. Considering the importance of non-antibiotic resistance (ABR) LAB as microbial starters, this study focused on isolation and characterization of non-ABR LAB from the household and dairy industrial food waste and assess its suitability for biomass production of the bacteria. Among 75 total LAB isolates, around 60% from hostel food, 33% from household waste and 30% from dairy waste were identified as non-ABR LAB against 7 antibiotics examined. Interestingly, ABR incidence of dairy waste is much higher than that of household waste. Most LAB strains were resistant to Tetracycline and Neomycin and showed a wide range of Vancomycin resistance, indicating serious threats to the food waste like environment. Likewise, the susceptibility of LAB to β-lactam group antibiotics was more than 10% across the food waste samples. This study emphasizes the antibiotic resistance-free lactic acid bacteria from dairy and household food waste biotransformation to starting culture biomass.
