title: Culture-to-culture physical interactions causes the alteration in red and infrared light stimulation of Escherichia coli growth rate.
abstract: Escherichia coli MC1061 cells were irradiated at 660 and 900 nm, incubated in M9 and LB media with the use of a specially constructed device, and assayed for growth rate. There was a reduction of growth rate stimulation when the irradiated culture was cultivated jointly with the non-irradiated one. In the same time, the irradiated culture extended the invigorate effect on the non-irradiated one. It is proposed that the effects observed were mediated by culture-to-culture physical interactions.
