Abstract: Clostridium phytofermentans cells (American Type Culture Collection 700394T) and all other strains of the species can ferment materials such as biomass into useful products and coproducts, such as ethanol, hydrogen and organic acids. Compositions that include Clostridium phytofermentans are also disclosed.

Abstract: A pressure sensitive element or array is provided which includes at least one first conductor on a first substrate and at least one second conductor on a second substrate, with a first conductor and a second conductor intersecting adjacent to each other at a sensor point and a pressure sensitive material being between the first and second conductors at each such sensor point. A mechanism is also provided which applies a predetermined prepressure to the substrates at least at selected ones of the sensor points. The prepressure for a preferred embodiment is provided by joining the substrates with an air-tight seal around a periphery of at least the pressure point to which prepressure is to be applied and by creating a reduced pressure area between the substrates within the sealed periphery. For preferred embodiments, the reduced pressure is a substantial vacuum, causing substantially atmospheric pressure to be applied to the sensor points.
