Sorangium cellulosum is a soil-dwelling Gram-negative bacteria of the group myxobacteria. It is motile and shows gliding motility. It has an unusually-large genome 12,200,000 base pairs in size.
Metabolites secreted by Sorangium cellulosum known as Epothilones have been noted to have antineoplastic activity. This has led to the development of analogs which mimic its activity. One such analog, known as Ixabepilone has recently undergone clinical trial in the treatment of metastatic breast cancer and is currently under new drug application review by the US FDA.
