Yeast cells are genetically modified to disrupt a native metabolic pathway from dihydroxyacetone to glycerol. In certain aspects, the yeast cell is of the genera Kluyveromyces, Candida or Issatchenkia. In other aspects, the yeast cell is capable of producing at least one organic acid, such as lactate. The yeast cells produce significantly less glycerol than the wild-type strains, and usually produce greater yields of desired fermentation products. Yeast cells of the invention often grow well when cultivated, despite their curtailed glycerol production.

A portable conveyor system receives and conveys particulate material to downstream equipment. The system includes a base frame, a material handling assembly carried on the base frame for depositing the material into the downstream equipment, and at least one adjustable feed conveyor to convey the material from a source onto the material handling assembly. The feed conveyor is movable in various manners relative to the base frame between a working position and a stored position. The material handling assembly includes a main conveyor assembly to convey material along the base frame from the feed conveyors to an elevating assembly at one end of the base frame. The elevating assembly is collapsible in height relative to the base frame for transport.

A vertical support for a transport robot includes a column assembly and a driving assembly. The vertical support includes a fixed column frame and a movable column frame movably arranged on the fixed column frame. The driving assembly includes a traction assembly and a retractable assembly connected to the traction assembly. The traction assembly is connected to the carrying device and configured to drive a carrying device of the transport robot to move relative to the movable column frame. The traction assembly includes two sets of traction assemblies located at two opposed sides of the carrying device respectively, the retractable assembly is configured to drive the two sets of the traction assemblies to synchronously drive the carrying device to ascend or descend.
