Microbial contaminants of cultured Hibiscus cannabinus and Telfaria occidentalis tissues

Abstract

Nine microbial contaminants comprising of five bacteria and four fungi species were isolated from 
Hibiscus cannabinus and Telfaria occidentalis cultured tissues. The rate of occurrence of bacteria 
isolates was higher than that of fungi. The bacterial isolates includes Pseudomonas syringae pv 
phaseolicoli, Bacillus licheniformis, Bacillus subtilis, Corynebacterium sp and Erwinia sp. While fungal 
contaminats includes Alterneria tenius, Aspergillus niger, Aspergillus fumigatus and Fusarium 
culmorum. Possible sources of contamination and means of eliminating these contaminants is 
discussed.
