Teicoplanin shares many chemical and microbiological properties with vancomycin, but offers advantage over vancomycin. Most of these elements have been components of Zarrouk's medium (1966) suggested for Spirulina in the indoor cultivation, but for the outdoor cultivation, low cost nutrients have been replaced to minimize its economy. The strain was maintained in 500 mL sterilized Erlenmeyer flasks containing 100 mL Zarrouk’s medium (Zarrouk, 1966) at 30 ± 2 °C, pH 9 with continuous illumination using cool white fluorescent tubes (2500 Lux) and twice daily shaking by hand. supplemented with zarrouk medium at pH 9.

Properties like concentration of algae, concentration of flocculants, and effect of temperature on flocculation, effect of pH on flocculation is studied Alum showed good separation but it. A study showed that Zarrouk’s medium (ZM) was the best medium in terms of biomass productivity, while modified Blue-Green 11 medium (BG11) gave the highest chlorophyll, carotenoid, phycocyanin, and allophycocyanin contents [11]. The utilized carbonate-bicarbonate buffer gives a pH of 9. by incorporating selected nutrients of the standard Zarrouk’s medium (SM) and other cost-effective alternative chemicals. Algal mass was harvested every 3 weeks by continuous centrifuge, air dried and ground to powder form. This modified medium was derived from Guillard and Lorenzen's (1972) WC medium.
