NOVELTY - Raoultella ornithinolytica strain P1-A-19 is preserved in China General Microbiological Culture Collection Center under preservation number (CGMCC NO: 10267), and is new.    USE - Raoultella ornithinolytica strain P1-A-19 used for producing electricity in microbial fuel cells and preparing 10-deacetylbaccatin III (all claimed).    ADVANTAGE - The Raoultella ornithinolytica strain P1-A-19 converts baccatin III to produce 10-deacetylbaccatin III.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for screening transformed 10-deacetylbaccatin III, which involves:    (A) washing and sedimenting sludge and removing bottom inorganic sediment and surface water;    (B) obtaining the sludge as inoculum with moisture content of 95%;    (C) mixing the obtain sludge with nutrient liquid and placing in microbial fuel cell reactor for 10-20 days;    (D) stabilizing gradually voltage across load resistor that shows visible thick biofilm on the anode;    (E) separating cells form biofilm by scrapping;    (F) inoculating and suspending the obtained cell by inoculating loop into sterile water to obtain bacterial suspension;    (G) coating the obtained bacterial suspension on Bold's Basal solid medium that contains glucose as carbon source;    (H) culturing at 30 degrees C FOR 3-5 days;    (I) obtaining pure isolates from the culture medium;    (J) numbering and naming the obtained isolates;    (K) adding the obtained isolates into anolyte;    (L) inoculating the obtained isolate inoculum into the microbial fuel cell reactor, which is connected with external resistor and data acquisition device;    (M) running the reactor at room temperature;    (N) collecting the cells;    (O) crushing the obtained cells with toluene and adding susbrate i.e. baccatin III at 37 degrees C at 200 revolutions per minute for conversion (3 days); and    (P) identifying transformed product by thin layer chromatography, high-performance liquid chromatography and liquid chromatography mass spectrometry.
