General Information

EC Number General Information Comment Organism
4.2.2.1 physiological function loss of hylB or/and constitutively expressed hylZ has no significant effects on cell growth, lactic acid, and hyaluronan yields. The HylB mutant strain produces hyaluronan with an 18 % increase in molecular weight Streptococcus equi subsp. zooepidemicus
