Let us inform you the report
of the experiment on antibacterial effect of Nanocid on fungi (Aspergillus
sp.) First in 500cc erlens provide PDA culture medium
separately ,after putting in autoclave, various doses of
antibacterial; means 5,7.5,10 micro liter were added into erlens ,so
that 50,75,100 ppm volumes were provided ,nothing was added to the
forth erlen , so it was investigated as testifier. These culture
mediums were added to plates (with 9cm diameter) and after
coagulation a plan with 4 training and 4 repetition was done
accidentally . One ring of 3 days fungal disk (Aspergillus sp)
was added to each one of plates containing PDA culture medium with
different antibacterial concentrations , and to the culture
medium (PDA) testifier in the center of plates and kept in
incubator in 27°c . When growth of misilium fungi in testifiers plates was completed and the whole
plate was involved , investigation was done.(pic 1 and
2)
Results:
The rate of colony growth in
each training was investigated (table 1) and control percentage was
calculated according to the following formula:(table 2)

the trainings were
investigated in SAS soft ware (table 3)and as you can see in the
table ,trainings ,in level 1 :had a significant difference in
control and in training number 3 and 4 ; means 75 and 100 ppm
concentration of antibacterial, was about 71.5 percent, and in 50 ppm training of antibacterial was about 59.25 percent but there
hasn't been seen any control in testifier training (picture
