Bioremediation of heavy metals using newly isolated native algae from Balanagar effluent channel, Hyderabad

Natural algal samples were collected and tested for their efficiency to degrade the heavy metals like Lead, Arsenic, Chromium and Mercury. Overall, 10 algal samples were collected and tested for their degradation efficiency. The present study assessed the ability of the local algal stains to degrade the heavy metals. The following parameters were chosen for this research: Mercury, Cadmium, Chromium, Manganese, Iron, Copper, Zinc, Nickel and Lead. Among the ten isolates, one had to encourage degrading ability and apply genotypic approaches to the strain involved using the 16S rRNA gene sequence. We discovered the algal strain Pandorina morum YSCVR24 through NCBI BLAST analysis. The isolation grew most efficiently at pH 7.0, 30°C, and a 24-hour incubation period. Measurements of degradation potential showed that lead and arsenic had the highest removable rates (80 and 85%), whereas mercury and chromium had the lowest (62 and 65%). In addition to showing a reduction of 60–80% of all heavy metals evaluated, Pandorina morum YSCVR24 may be able to degrade heavy metals using plasmids, which may be used to modify plasmids to allow them to collect heavy metals.
