Basis of differentiation | Pour plate method | Streak plate method |
Definition | Is a microbial technique utilized for isolating and counting the number of viable microorganisms in a liquid sample | Is a microbial technique used to spread a liquid sample containing bacteria onto a solid surface, making it simpler to count and separate individual bacterial colonies |
Accuracy | Is highly accurate | Is comparatively less accurate |
Microbial growth | Anaerobes, aerobes, and facultative anaerobes can all be quantified | The only bacteria able to be quantified are anaerobes |
Use of glass spreader | Is not used | Uses a glass spreader |
Sample adding | Sample is added to the solidified medium using an inoculating loop | Sample is mixed with molten agar and poured into a plate |
Medium used | Requires solidified agar plates | Requires liquid molten agar media |
