First to be added Second to be added Volume of inoculum
STREAK PLATE METHOD Nutrient Agar (Melted) A loopful of bacteria from a slant No definite/exact amount (Only a Loopful)
POUR PLATE METHOD Bacterial Broth Nutrient Agar (Melted)
SPREAD PLATE METHOD Nutrient Agar (Melted) Bacterial Broth
1.0 mL or 0.1 mL
0.1 mL Count the number of colonies (number of microorganisms) microorganisms) Petri dish Alcohol Lamp Pipet Test tubes Glass Rod / L-rod
Purpose
For isolation of colonies only
Count the number of colonies (number of microorganisms) microorganisms)
Equipment (Glasswares)
Petri dish Alcohol Lamp Wire Loop
Petri dish Alcohol Lamp Pipet Test tubes
Type of Colonies
Surface Colonies
Advantage
* For isolation of bacterial cultures * Has distinct separate colonies
Disadvantage
* Higher Probability of Contamination Contamination prior to isolation.
Either Surface/ Subsurface Colonies *For Quantification of colonies in solid medium *Allows the growth and quantification of microaerophiles (Sufficient oxygen supply) * Picking subsurface colonies would interrupt other colonies by digging out of the agar * Microbes must withstand the agar temperature
Surface Colonies
* Cultures are never exposed to 45oC melted agar temperatures.
* More microbes, presence of more colony forming units.
