“…Loktanella was reported to be a dominant genus in the coastal microbial community (Cardoso et al, 2019), and large numbers of Loktanella strains have been isolated from tidal flat sediments (Park et al, 2013(Park et al, , 2014Tanaka et al, 2014). Trichococcus strains were characterized by their psychrotolerant ability, which was commonly isolated from environments at low temperatures such as cold spring (Zakharyuk et al, 2021). Lutibacter was reported to be predominant in shallow water marine sediment (Kerfahi et al, 2014), and some strains have been isolated from tidal flat sediments (Choi and Cho, 2006).…”

The booming mudflat aquaculture poses an accumulation of organic matter and a certain environmental threat. Protease-producing bacteria are key players in regulating the nitrogen content in ecosystems. However, knowledge of the diversity of protease-producing bacteria in coastal mudflats is limited. This study investigated the bacterial diversity in the coastal mudflat, especially protease-producing bacteria and their extracellular proteases, by using culture-independent methods and culture-dependent methods. The clam aquaculture area exhibited a higher concentration of carbon, nitrogen, and phosphorus when compared with the non-clam area, and a lower richness and diversity of bacterial community when compared with the clam naturally growing area. The major classes in the coastal mud samples were Bacteroidia, Gammaproteobacteria, and Alphaproteobacteria. The Bacillus-like bacterial community was the dominant cultivated protease-producing group, accounting for 52.94% in the non-clam area, 30.77% in the clam naturally growing area, and 50% in the clam aquaculture area, respectively. Additionally, serine protease and metalloprotease were the principal extracellular protease of the isolated coastal bacteria. These findings shed light on the understanding of the microbes involved in organic nitrogen degradation in coastal mudflats and lays a foundation for the development of novel protease-producing bacterial agents for coastal mudflat purification.
