Moreover, biomimetic co-precipitation-based -carrageenan functionalization of OCP might also improve precursor cell spreading as well as metabolic activity, which would provide a basis for further research on the suitability of -carrageenan functionalization of OCP coating on dental titanium implants. It appears to be particularly destructive to the digestive system, triggering an immune response and causes inflammation, which can lead to gastrointestinal disease including ulcerative colitis, intestinal lesions and colon cancer. Moreover, we have shown earlier that exogenously added -carrageenan promotes migration, adhesion, spreading, and osteogenic differentiation of MC3T3-E1 preosteoblasts in vitro (Cao et al., 2021). This can be explained by the fact that the enzymatic activity of the bacterial cell was increasing for the production of a higher amount of enzymes responsible for hydrolysis of -carrageenan followed by catalytic desulfation reaction to produce the proton. The fraternity was established at the University of Virginia in This might indicate that -carrageenan in the OCP coating provides more sites for osteoblast recruitment, which might lead to enhanced bone formation, which would be beneficial for osseointegration. The biosensor exhibited a significantly higher response towards -carrageenan when compared with other types of carrageenan (p<0.001) and negligible responses were obtained from both - and -carrageenan over the concentration range of 1100 ppm, which suggests good selectivity of the potentiometric whole cell biosensor towards -carrageenan. Kappa carrageenan also forms a strong interaction with locust bean gum and konjac glucomannan, but this interaction is not desirable for beverage due to the resulting high viscosities ( Stone and Nickerson, 2012; Imeson, 2010 ).
