A class room practical to study molds on bread was performed
by 1
st
semester undergraduates.
Target group
– 20 students who worked in batches of 5 each
Materials used
–
4 slices of bread (any brand)
4 plastic bags
Sealing tape
Black marker

Drew a grid of 5X5 squares on the bag with a
marker
A and B groups kept the experiment in an
incubator that was set at 25
0
C; C and D set the slices in refrigerator
The experiments were examined each day and the
boxes in the grid for moldy growth noted down
The experiment was discontinued after 5 days due
to excessive moldy growth in the sets kept in incubator, while the ones in
refrigerator had to be kept for 2 weeks for results to begin
The moldy growth obtained was observed
using foldscope and the results are being posted on
