Anatomizing extracellular polymer of Calothrix desertica with its anti-oxidation and anti-nutrient profiling

Calothrix desertica having a semilunar apical heterocyst is proficient at excreting 1.2 g/L of extracellular polymers (EPsC) in 45 days. The refined EPsC constitutes 430 mg/g glycogen, 390 protein, and 14.6 glycoproteins (GPs). glycoprotein estimation was performed by two step hydrolysis methods with H2SO4. peak between 10 mAU to 20 HPLC, 1400 cm-1 1700 FTIR, 40kDa- 35kDa bands SDS-PAGE authenticates the presence EPsC. agglomerate 1000 nm 3000 size Zeta potential -20 mV 5 determined using DLS. Further nanosizes 30 150 50,000 X 40 60,000 measured FE- SEM. DPPH assay H2O2 scavenging showed 73.1% 70.8% anti-oxidant activity EPsC, which coequally efficient as standard gallic acid. biopolymer can also be used reducing agent, per anti-nutrient studies.
