Abstract

Attempts had been made to improve the sensitivity of whole cells of cyanobacterial species and
its thylakoidal fragments where PSII is the main target for most of the photodynamic herbicides.
We screened out the potential of tolerance. These biologically active materials are capable of
oxygen evolution by photolysis of water in presence of light. We performed growth studies,
pigment analysis, bioenergetic studies by using clark’s oxygen electrode both in free and
immobilized state. We recorded spectral properties, oxygen evolution studies in presence of
various herbicides. We determined the I50 values for the whole cells of different species and
also recorded peak shifting

Keywords
