Paper Abstract

The effect of laser irradiation is one of the most important factors that affect the bacteria survival due to the wavelengths that emit the different light sources. The high-intensity broadband visible light (400–800nm) can reduce viability of bacterial strains. The main objective is to assess the most effective wavelengths of visible light in growth of four beneficial rhizobacteria. The survival of bacterial cells following illumination was monitored by optical density after exposure of the suspended bacteria to light at different time of incubation. Bacterial grow under the same conditions but without light exposure as controls. The visible light with wavelength between 450-590nm increase the bacterial growth in vitro conditions.
