In this paper, we present a study of stimulated Brillouin scattering (SBS) by E-coli, B.subtilis and coliphages in water. We found the Lamb-like dip in the spectra of SBS in the presence of organisms in water (higher than 1 cells/ml) at excitation by laser radiation with wavelengths 810 and 1017 nm and power 40¬150 mW. The mathematical model of non-linear interaction of the laser radiation with double-stranded DNA, consisted in two antiparallel chains, was designed to explain this phenomenon.
