Isolation and Identification of Bacteria and Actinomycetes Isolated from Wilting Banana Plants (Musa Sp.)

摘要

In Indonesia, wilting disease in banana due to Fusarium has spread in several areas. In addition, fungi, bacteria, and actinomycetes are also known to cause the disease. In this research, isolation and identification of bacteria and actinomysetes causing the wilting of rot and rhizosphere were done. Identification used several stages of biochemical tests. There were 40 bacteria] isolates with 9 generas, which were Pseudomonas sp., Xanthomonas sp., Caulobacter sp., Erwinia sp., Eschericia sp., Ralstonia sp., Neisseria sp., Staphylococcus sp., and Proteus sp. Whilst 18 isolates of actinomycetes were obtained with 7 generas, including Nocardia sp., Actinobiospora sp., Nocardiopsis sp., Streptomyces sp., Streptoverticillium sp., Streptosporangium sp., and Microbispora sp.
