The present invention relates to the application of isolated promoters and synthetic dominant selection constructs and enhancers for gene targeting for efficient production of genetically modified cells in a species selected from the Pucciniomycotina and Ustilaginomycotina subphyla, in particular, species selected from theorgenera.

Genetic manipulation and expression systems for Pucciniomycotina and Ustilaginomycotina subphyla

A heated reaction gas comprising methane is contacted with first and second catalysts to catalyze production of an aromatic hydrocarbon. The first catalyst is more active than the second catalyst for catalyzing aromatization of methane, and the second catalyst is more active than the first catalyst for catalyzing aromatization of ethane. A reactor for producing aromatic hydrocarbons from the reaction gas may have a conduit defining a reaction zone for the reaction gas to react therein, and the first and second catalysts may be disposed in the reaction zone.

Aromatization of methane with combination of catalysts

A process for the pre-treatment of Mo/ZSM-5 and Mo/MCM-22 catalysts is provided, which process comprises heating the catalyst at 500&#xb0; C. in the presence of propane. The treated catalyst, when used in the non-oxidative dehydrogenation of methane demonstrates improved benzene yield and catalyst stability as compared to catalysts pre-treated with He, methane or H.
