prepared a dilution series for detection of bacteria in food as follows:
a. 2gm food + 18 ml water
b. 1ml a + 19ml water
c. 1ml b + 24 ml water
d. 1ml c + 9 ml water
e. .1ml d + 9.9 ml water
f. 1 ml e + 9 ml water
g. 1ml f + 9 ml water
Spread plates (0.2ml) gave the following results:
a. TNTC
b. TNTC
c. TNTC
d. TNTC
e. 128, 119
f. 18, 16
g. 2, 0
How many organisms were present in 1gm of the original sample?
