Advances in employing omics and bioinformatics to reveal the potential of halophilic bacteria for biodegrading proteinaceous high-salt food waste

The waste biomass generated by the food processing industry poses significant concerns for environmental health. This mini review sheds light on the emerging challenge of proteinaceous high-salt food waste (PHFW) due to its high salinity. It aims to explore the potential of halophilic bacteria and their robust enzymes in addressing PHFW through advance approaches, including omics and bioinformatics. The integration of multi-omics and bioinformatics approaches could reveal the uncharted potential within the genomes of these halophilic bacteria, particularly their proteolytic capabilities. Furthermore, employing salt-tolerant proteases offers promising biotechnological applications for valorizing PHFW into valuable resources, such as bioactive peptides. The integration of advanced technologies not only elucidates the versatility of the halophilic proteases but also facilitates the development of functional food products from the subsequent hydrolyzed peptides. Though, transitioning these findings from laboratory settings to large-scale industrial applications presents various formidable challenges. In essence, the advancement in unlocking the potential of halophilic bacteria for biodegrading PHFW is emphasized as a potential bioeconomic solution.
