Bio-assay of heavy metals byAspergillus niger—sensitivity of a new strain

  • Published:
Proceedings / Indian Academy of Sciences

Summary

The standard ‘M’ strain ofAspergillus niger van Tiegh. which is being used in many laboratories as a biological test to detect the presence of some heavy metals in minute traces has been compared with a new strain of the same fungus, isolated in this laboratory, from the rhizosphere ofCajanus cajan, and designated as M.U.B.L. 1.

The new strain appeared to be less sensitive to traces of manganese, and more sensitive to copper, and perhaps molybdenum also, than the ‘M’ strain. Further studies regarding the stability of the new strain and also attempts, to secure a greater degree of purity of media are being conducted.
