NOVELTY - Manufacture of hydrogen comprises providing bacterium, which is Rhodopseudomonas spheroides strain AS1.1737 (ATCC 17023); connecting five 250 ml high temperature glass cylinders, each filled with culture medium (200 ml) to the inclined bacterium; making seed culture medium; obtaining sewage from wet pig excrement; before fermenting, sterilizing the sewage in a sterilized boiler at 121degrees C for 20 minutes; cooling to 25degrees C; and inoculating sewage (10 vol.%) to the seed culture medium.    USE - For manufacturing hydrogen.    DETAILED DESCRIPTION - Manufacture of hydrogen comprises providing bacterium, which is R. spheroides strain AS1.1737 (ATCC 17023) from Microorganism Research Institute of Chinese Academy of Sciences; preparing the culture medium (pH 7.0) comprising extract from beef (1.5 g), extract from yeast (1.5 g), tryptone (5.0 g), glucose (1.0 g), sodium chloride (3.5 g), potassium phosphate (K2HPO4) (4.8 g), KH2PO4 (1.3 g), agar (15.0 g), and distilled water (1.0 L); mixing the culture medium; putting 200 ml culture medium into each of five 250 ml high temperature glass cylinders; after sterilization, connecting to the inclined bacterium; making seed culture medium; mixing the wet pig excrement and water; soaking the pig excrement and mixing; filtering with 40 mesh screen to remove the rice straw, mud, and sand, obtaining a filtrate, which is the pig excrement sewage; before fermenting, sterilizing the sewage in a sterilizing boiler at 121degrees C for 20 minutes; cooling to 25degrees C; and inoculating sewage (10 vol.%) to the seed culture medium.
