Experiment 1: Detection of bacterial population and distribution in plant tissue culture laboratory
The laboralory in plant tissue culture in Faculty of Science at Maejoe University was investigated for bacterial density and distribution of bacterial strains in various areas according to the area numbers as shown in fig. 1. The bacterial population were high in the area of pathway(9), preparation room(10), autoclave room(11) and cloth changing room(3) contained high level of bacterial population as shown in Fig 2. The isolated bacteria were found in the different area of laboratory which comprised of 17 genera and the distribution of bacterial species was the highest in the area of pathway and preparation room(Fig.3).
