| Popis: | The growth of a non-axenic Phormidium bigranulatum-dominated mat was tested under a range of chemical parameters and types of substrate. Total biomass yield (in term of mg chlorophyll a) of mats grown on muslin cloth (0.64 mg) and cotton mesh (0.62 mg) were significantly higher than those on other substrates, such as, nylon net (0.50 mg), sands of river Sone (0.43 mg) and river Ganga (0.30 mg), rice husk (0.38 mg) and saw dust (0.21 mg). The Phormidium mat would be easy to handle in bioremdation process as it grew well enmeshed in nylon net. The mat biomass increased with increasing phosphate enrichment of the medium up to 0.25 mM, whereas higher concentrations were inhibitory. At low levels of phosphate ( |
