Abstract:

Antifreeze proteins (AFPs) are special proteins that inhibit the growth of ice crystals at low temperatures to protect cells from damage by ice crystals. They come from a wide range of sources, and have been found in fish, insects, plants, bacteria, algae and fungi. In contrast to research on AFPs derived from animals and plants, research on AFPs derived from bacteria has yet to be systematically reviewed and analyzed. Therefore, this review reports on the latest research findings on bacterial AFPs, focusing on four bacteria species and their AFPs. We also discuss the prospects and potential applications of bacterial AFPs.
