Biomass densities attained after 3-days of growth in the AP as a
function of HTL temperature and dilution are illustrated in Fig. 4-a and
summarized in Fig. 4-b confirming the hypothesis that higher biomass
productivity could, in fact, be attained by recycling the AP of HTL than
with the standard growth medium. These findings also confirm that
G. sulphuraria can be successfully grown heterotrophically on recycled
A
