Arabinose biopurification by Ogataea zsoltii yeast

Arabinose is a five carbon sugar which exists in nature as a component of hemicellulose and pectin polymers, naturally occurs in L - configuration . It is used as diet controlling food additive, important intermediate for anti - virus drug synthesis and as base material in the production of vitamin B 2 , among other applications . Commercial production of L - arabinose begins with the acid hydrolysis of gum arabic followed by expensive purification steps. Nowadays biopurification have become an attractive approach for purifying high - value sugars from lignocellulosic hydrolysates . Ogataea zsoltii yeast was investigated in terms of its ability to perform arabinose biopurification on semidefined medium and on the supernatant of acidi c hydrolysis of corn fibre. Arabinose biopurification was performed in shake flasks and bench - top bioreactor under aerobic conditions. Based on our results, this strain can be used for arabinose biopurification on both medium , resulting in near 90 % purity for arabinose
