Method The present paper deals with an experimental work in which the growth kinetics of an aerial bacterial colony in a closed system was studied using Laser Induced Fluorescence (LIF) Technique. Study on growth kinetics of bacterial colony using LIF was carried out by doping Rhodamin B dye in culture medium. Rhodamin B is an appropriate dye for doping because of its high fluorescence quantum efficiency.
Comments A plot of area of bacterial colony against time is shown in Fig. 5. Here area increases exponentially after 25 h of growth. Rate of exponential growth is calculated to be 0.039 mm^2 /h by theoretical fit. This indicates the exponential growth of bacterial population associated during this period to exponential phase of colony growth.
