used different experimental conditions (broth, aeration, agitation)
achieved HA productions of 4.2 g L−1 with Mw of 3.1 × 103 kDa and
Yh/s = 0.07 g/g. Recently, Liu et al. [35] obtained concentrations of
6gL−1 of HA but with a final Mw of 45 kDa by using 0.15 g L−1 of
hyaluronidase in the culture media.
