Abstract:
A biopesticide composition includes a solvent and a plurality of rhamnolipid complexes, each rhamnolipid complex including a rhamnolipid complexed with a cation. The biopesticide composition may include a slower-releasing rhamnolipid-based material and a faster-releasing rhamnolipid-based material. The biopesticide composition may be in the form of a coating or a pellet.

Abstract:
A method for reducing the free fatty acid content of a feedstock includes the steps of providing a free-fatty-acid-containing feedstock, treating the free-fatty-acid-containing feedstock to reduce the free fatty acid content thereof, where the step of treating includes combining at least one of an algae and a coagulant to the free-fatty-acid-containing feedstock, and producing a product from the treated feedstock.
Abstract:
Improved enzyme based methods of separating protein from protein-rich material are provided. A method can include utilizing a modeling equation to more effectively hydrolyze the various types of carbohydrates present in a protein-rich material. A method can include a fed-batch method of incrementally adding a protein-rich material, an enzyme broth, or both a protein-rich material and an enzyme broth. A method can also include partially or completely recycling the hydrolysate.
Abstract:
A method for treating solid organic materials includes providing phagotrophic algae, providing solid organic material, combining the algae and the solid organic material, allowing the algae to grow by engulfing or uptaking the solid organic material, forming an algal product, and collecting the algal product. The method can also include a pretreatment step. The solid organic material can be waste activated sludge. A system for treating and disposing solid organic material is also provided.
Abstract:
A method for producing arabitol, and more particularly to producing arabitol in a major amount based on a total weight of all polyols produced and in relatively high concentration from a mixture including a carbon source such as glycerol. The method includes in one embodiment utilizing select yeast strains to produce arabitol in high yield while minimizing the amounts of other polyols, using carbon sources such as glycerol as a component in a medium. In a beneficial embodiment, biodiesel byproduct glycerol is used as the substrate for arabitol production.
Abstract:
Provided is a method of modifying fungal morphology. The method comprises introducing an amount of a surfactant to a fungus, or to a growing mixture comprising a fungus, wherein said amount of a surfactant is sufficient to induce a change in the morphology of said fungus.
Abstract:
A method for removing a gas compound from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the gas compound to be removed into the gas vesicles, and placing the gas vesicles contacted with a medium such that the gas compound is removed from the site to the medium. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium. Then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.

Abstract:
A method for producing arabitol may include providing a fermentation culture having a microorganism and a carbon source; allowing the microorganism to ferment the carbon source; monitoring a process condition of said step of allowing the microorganism to ferment the carbon source; and collecting a product from the fermentation culture after said step of monitoring a process condition indicates that a predetermined change in the process condition has occurred. Other methods may include steps of providing soybean-based lignocellulosic hydrolysate as a carbon source for a fermentation culture, and modifying the pH of one or more of the growth phase and the stationary phase of a fermentation process.
