The daily observations of the variations in cellular macromolecular composition () and f highlighted a peak for carbohydrate/amide (C/P) ratio on day 7 and day 12 (highest), inferring a gradual increase in polysaccharides with TOC assimilation. High C/P ratio indicated a net decrease in the protein content (with TN and NH4-N removal, as discussed earlier) and the synthesis of polymeric carbon secretions helped in aggregation of algae during floc formation. This further demonstrated the potential NH4-N limitations in triggering the lipid synthesis and accumulation. In the present experiment, the C/P ratio of the algal consortia showed 4.58-fold increase that varied from 3.95 to 18.15 on day 12. This was higher compared to an increase of 1.14 and 2.24 times in Phaedactylum tricornitum ( ) and lower than 7- and 9.6-fold increase in Chlamydomonas reinhardtii ( ) and Microcystis auregonosa ( ) respectively. Nitrogen starvation leads to diversion of carboxyl part (precursor to protein) to lipid and polysaccharides enhancing C/P values. This is in contrast to low C/P (0.6) in Pediastrum duplex under natural conditions ( ).
