Abstract

Hyaluronic acid (HA) has great importance in biomedical applications. In this work, a novel nanoparticle-based method that stimulates the hyaluronic acid (HA) production by the bacteria subsp. Zooepidemicus has been reported. CNTs with diameters of 40-50 nm and lengths of about 20 mm were used at four different concentrations (0, 10, 25, 50, and 100 μg) to the bacteria and determined the mass of the produced HA in dependence on the exposure time under UV-irradiation. The results clearly showed that the exposure for one minute with low power UV light (254 nm) and 100 µg (CNTs) treatments steadily increased HA production from the control (0.062 g/L) to the highest value (0.992) g/L of HA. The incubation of the streptococci with CNTs led to an increase of the HA production by a factor of 4.23 after 300S exposure time under UV light, whereas the HA production was no significant enhancement under visible light. It is explained that the CNTs nanoparticle-stimulated increase of the HA production with the internalization of the nanoparticles by the bacteria since they "serve as co-enzymes" under induced mutation by UV-irradiation. Transformation process was carried out and showed that the major protein band of was observed in the Streptococcus DH5α. RAPD analysis indicates that the amplified DNA fragments and the percentage of polymorphism was similar between and Streptococcus DH50α. The chemical structure and molecular weight of the photoproduced HA from was similar to the chemical structure of the standard sample.
