Other differences include the use of ammonium chloride as the nitrogen source in TAP
medium versus sodium nitrate in A+ medium, the presence of acetate in TAP, and the presence of vitamin B12 in A+ medium. To accommodate the growth of both
C. reinhardtii and Synechococcus sp. PCC 7002 in coculture, both the TAP and A+ media were modified (henceforth referred to as modified TAP and modified
A+, respectively).
