Microbiology of controlled rotting of egusi (Colocynthis citrullus L.) fruits for the harvesting of the seeds

Microorganisms isolated from naturally rotting egusi fruits which are used as a source of dietary seeds, were mainly bacteria: Bacillus subtilis, B. licheniformis, B. polymyxa, B. megaterium, B. pumilus, Lactobacillus plantarum, La. brevis, Leuconostoc mesenteroides, Enterobacter aerogenes, E. cloacae, Klebsiella aerogenes, K. pneumoniae, Staphylococcus epidermidis, S. aureus, Micrococcus and Candida spp. The rotting period of egusi fruits could be decreased from 120 to 72 h by using a mixture of B. subtilis and B. licheniformis.
