Table 5. Spectrophotometric analyses of chlorophyll in 4A+, chli1-1, chli1-7 and chli1-8 strains.

Chlorophyll analyses were done on three biological replicates for each strain. Strains were grown mixotrophically in TAP under 15–20 µmol photons m ^-2s ^-1. Mean values are shown in the table. Statistical error (± SD) was ≤10% of the values shown. ND: not detected.
