STANDARD METHODS AGAR W/ STARCH

Standard Methods Agar w/Starch is formulated as described by Buchbinder et al which is recommended by APHA and FDA.
APHA recommends the use of pour plate technique. The samples are diluted and appropriate dilutions are added in Petri plates. Sterile molten agar is added to these plates and plates are rotated gently to ensure uniform mixing of the sample with agar. The poured plate count method is preferred to the surface inoculation method, since it gives higher results. Standard Methods Agar w/Starch is also suitable for enumerating bacterial count of sterile rooms.
