Growth of Desulfovibrio desulfuricans (API strain) was found to take place in an atmosphere of hydrogen on the agar surface of complex media, including yeast extract (Difco), and Trypticase Soy Agar (BBL) without any added reducing agents. For growth on a 2% yeast extract-agar surface in the absence of hydrogen (nitrogen atmosphere), sodium lactate was required in the medium. Growth on the surf...

ABSTRACT Renewable energies have been occupying more and space in energy matrices worldwide, lignocellulosic biomasses are promising for these sources. This study aimed to develop a fuzzy model optimize the ferrous sulfate concentration temperature pre-treatment of elephant grass. Five concentrations (10, 15, 20, 25 30 mM) three temperatures (25, 40 55 ºC) were used as input. The application ev...
