Abstract: The present invention relates to genetically modified yeasts that can use lactate as a carbon source to produce a fermentation product. In one aspect, the yeasts can consume glucose and lactate simultaneously to produce ethanol. In one aspect, the genetically modified yeast is transformed to include a monocarboxylic/monocarboxylate transporter. In one aspect, the yeast can include one or more heterologous genes encoding lactate dehydrogenase (cytochrome) (EC 1.1.2.3 and/or 1.1.2.4).

Abstract: A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.

Abstract: Disclosed are methods and apparatus for providing portable or fixed solar array support systems. Embodiments of the invention include an apparatus that holds two multi-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments.

Abstract: Disclosed are methods and apparatus for providing portable or fixed solar array support systems. Embodiments of the invention include an apparatus that holds four 60-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments.

Abstract: Disclosed are hinges having specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. In some embodiments, the stops may limit the hinges to open no more than 90 degrees. In other embodiments the stops may limit the hinges to open no more than 180 degrees. The hinges provide stability to any structure they are used with.

Abstract: Disclosed are methods and apparatus for providing portable solar array support systems. Embodiments of the invention include an apparatus that holds four 60-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments. Embodiments of the foldable solar array system are constructed from steel components, and feature proprietary integrated hinges to minimize the size and complexity of the system. The hinges are specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. These may be 90° hinges on the panel arms and swing arms, and may be 180° hinges on panel-to-panel hinges. The panel-to-panel hinges also allow for an offset based on the thickness of the solar panels and make the solar panels lay flat when open and stack face to face when closed.
