Assessing Growth Potential and Useful Biochemical Attributes of Selected acid Tolerant Cyanobacteria

Assessing Growth Potential and Useful Biochemical Attributes of Selected acid Tolerant Cyanobacteria.

Cyanobacterial strains belonging to Nosctoc, Anabaena and Cylindrospermum were isolated from rice grown acidic soils of Kerala, Nagaland and Tea garden of West Bengal. These were grown, maintained and analysed for growth potential and selected biochemical attributes. The experimental results of this study showed that some cyanobacterial strains were acid tolerant achieving higher growth rate at pH 4 and 4.5 rather than 5.5. The pigments and cellular constituents of these strains showed variability under three acidic pH indicating their specificity to regulate adaptability to acidic soils.
