Abstract:
The growth kinetics of an aerial bacterial colony on solid agar media was studied using laser
induced fluorescence technique. Fluorescence quenching of Rhodamin B by the bacterial colony was utilized
for the study. The lag phase, log phase, and stationary phase of growth curve of bacterial colony was identified
by measuring peak fluorescence intensity of dye doped bacterial colony.

Abstract:
Optical fiber based laser induced fluorescence (LIF)
measurements were carried out using Rhodamine B to analyze
two different species of bacteria , a Gram-positive bacteria
namely Bacillus .cmithii , and fibrin alginolvticus, a Gram-'
negative bacteria . The fiber sensor was clearly able to distinguish
between the two species of bacteria . Quenching effect of the dye
Rhodamine B by Bacillus smitltii was observed . The effect of dye
on the samples was also studied in detail.
