Fig. 4From: Metabolic engineering to improve production of 3-hydroxypropionic acid from corn-stover hydrolysate in Aspergillus speciesThe effects of manganese and nitrogen sources on 3-hydroxypropionic acid production in A. niger transgenic strain An3HP/pyc2 grown at 30 °C and 200 rpm for 7 days. A The effects of manganese on 3-HP production and B the effects of different nitrogen sources on 3-HP production. The data are the average of three biological replicatesBack to article page
