The streak plate technique is the most popular method for isolating specific bacteria from a sample containing a mixture of microorganisms. Streak plate technique is used to grow bacteria on a growth media surface so that individual bacterial colonies are isolated and sampled.
for isolating bacteria: the streak plate, the spread plate, and the pour plate. In the streak plate technique, a loop is used to streak the mixed sample many times over the surface of a solid culture medium in a Petri plate. Theoretically, the process of streaking the loop repeatedly over the agar surface causes the bacteria to

The spread plate method is a technique to plate a liquid sample containing bacteria so that the bacteria are easy to count and isolate. A successful spread plate will have a countable number of isolated bacterial colonies evenly distributed on the plate. The spread plate method uses a tool called a plate spreader (or hockey stick).
Here we introduce a novel technique facilitating streaking in ambient air, i.e., the direct measurement of the light field under ambient conditions. Our approach relies on the measurement of transient currents in ambient-air plasma, recently demonstrated by Kubullek et al. [ 19 ], and it leads to an order-of-magnitude simpler implementation of ...

To develop a plate with permanganate, spray or dip the plate and heat it with a heat-gun. Hold the plate face up 10 to 20 cm above the heat gun until the bulk water evaporates. Then move the plate to 5 to 10 cm above the heat gun and heat it until white/yellow/brown spots appear. Overheating will turn the entire plate brown, obscuring the spots.
