Growth and biochemical profile of two cyanobacteria affected by carpet industry effluent

Abstract

The mesophillic cyanobacteria Anabaena flos-aquae and Synechococcus cedrorum were grown in various concentrations of carpet industry effluent collected from Bhadohi District of U.P., India. The changes in growth and biochemical profile were studied. The effluent was stimulatory for the growth of both the cyanobacteria when used between 5% to 50% concentrations. Anabaena flas-aquae showed maximum stimulation of growth at 25% concentration while for Synechacoccus cedrorum the concentration was 50%. These two species of cyanobacteria could be grown even in 100% concentration, but the growth was very poor. In all stimulatory levels of effluent, these cyanobacteria also showed increase in various macromolecule contents of the cell, i.e., chlorophyll, carotenoids, phycobilliprotiens, proteins and carbohydrates. Out of the two cyanobacteria studied, S. cedroruni was found to be more tolerant to the effluent.
