2.6. Microbiological analysis
Microbiological analyses of sprouts obtained from control and
treated seeds were performed. Microbial counts of sprouts from
untreated seeds were used as initial values for calculating logarithmic
reductions in microbial counts of sprouts from treated seeds.
Mung bean sprouts were added to buffered peptone water (BPW)
(Oxoid, Unipath, Ltd., Basingstoke, UK) at a ratio of product to medium
1:9, and homogenized for 1 min on medium speed in a Stomacher
Laboratory Blender Model 400 (Seward Medical, London,
UK). One ml of each suspension was pour plated in triplicate on different
media for the counting of the following microorganisms: Total
aerobic mesophile populations on Tryptone Soya Agar (TSA),
incubated at 30 C for 72 h; total and faecal coliforms on Violet
Red Bile Agar (VRBA) containing lactose as carbon source,
incubated at 37 and 44 C, respectively, for 24 h; moulds and
yeast on Sabouraud Chloramphenicol Agar, incubated at 23 C for
72 h.
