A Method for the Experimental Determination of Light Absorption by Aquatic Heterotrophic Bacteria.
A method has been setup for the experimental determination of the volume coefficient for light absorption IN-VIVO by aquatic heterotrophrc bacteria. The described application of the method is for the measurement of the absorption of the fraction pf bacteria that pass through the commonly used GF/F filter, which remain unaccounted for. The experimental samples were prepared by successive water filtrations through GF/f and 0.22 mum MILLIPORE membranes. Light- transmission and light-reflection measurements of the filter-retained samples were performed using a dual-beam spectrophotometer equipped with an integrating-sphere attachment.
