ISOLATION AND CHARACTERIZATION OF HEAVY METAL RESISTANT FUNGAL ISOLATES FROM FOUNDRY SOIL SAMPLES IN COIMBATORE, TAMILNADU, INDIA Authors: N. Gunasheela And Hema Shenpagam N*
ABSTRACT
In the last few decades, heavy metals pollution has become a serious environmental
problem. The potential technology needs to be developed that can remove toxic metals found in
contaminated environments. In this present study, foundry soil samples were collected and
isolate the various fungal genera. This study was undertaken to determine the resistance levels of
different concentrations of heavy metals (lead and zinc) using filamentous fungi of Neurospora
spp and A.terrus. Based on the results, the A.terrus gave the highest tolerance ability of zinc
(4.5mM) and lead (3mM). Those cultures were further checked for their potential to produce
organic acid. Furthermore, the potential isolate was subjected to molecular characterization of
18S rRNA for confirmation, according to blast analysis, which isolate was A.terrus. The present
study shows that heavy metals contaminated foundry soil can be considered a valuable natural
source of resistance isolates, which can be used significantly as bioremediation techniques.
