Sorangium cellulosum can product many secondary metabolites that is unique structural and makes these microorganisms highly attractive for drug development, especially epothilone, on cancer cells a cytotoxic macrolide which is naturally produced by Soxhlet cellulose that have the action of microtubule stabilization, is a promising anticancer drug. In this research, the factors affecting the regeneration and preparation of the protoplast of Sorangium cellulosum were discussed, those were regeneration media, enzymes and osmotic stabilizers. This study provide the distruction for improving the production of epothilone through genome shuffling, mutation, fusion and transformation.

THE MOST IMPORTANT pathological problem encountered by commercial growers of poinsettias ( Euphorbia piilcheirima Willd.) is caused by a complex of fungi composed of Thielaviopsis basicola (Berk. & Br.) Ferr., Rhizoctonia solani Kuhn, and Pythium ultimum Trow. Collectively these three organisms cause a condition referred to as the poinsettia root rot complex. Since more research has been conducted on P. ultimum and R. solani than on T. basicola, the present research was originally designed to investigate some of the environmental factors affecting the growth of Thielaviopsis and the development of the root rot caused by it. However, another fungus, Chalaropsis thielavioides Peyronel, frequently was obtained in isolations from diseased greenhouse poinsettias. Since C. thielavioides had not been reported as being a part of the poinsettia root rot complex, the author decided to investigate its importance as a pathogen on poinsettias. Numerous similarities between C. thielavioides and T. basicola were evident. The object of this work was to compare the two fungi. Prior to undertaking such a study, the pathogenicity of Chalaropsis on poinsettias had to be established. A comparison of Chalaropsis and two isolates of Thielaviopsis was made to determine the effects of environment on the growth of the fungi and the ability of the two fungi to produce disease symptoms on poinsettias.

The saprophytic survival of Ophiobolus graminis was studied under laboratory and field conditions using artificially-infected wheat-straw buried in a Victorian Mallee soil.In pot tests, survival was prolonged by applications of ammonium sulphate, unaffected by superphosphate dressings and reduced by growing oats over infected straw. The observed effect if the nitrogenous soil amendment was not dependent upon the presence of Rhizoctonia solani as reported for South African soils.In a field experiment, survival was reduced significantly more by growing various plant species over infected straws than by maintaining fallow conditions. O graminis was isolated from all species, including dicotyledons, sown over infected straw
