Abstract:
A method for the production of a rhamnolipid. The method includes culturing in a fermentation medium an organism capable of producing a rhamnolipid to form a fermentation broth comprising at least one rhamnolipid and having a pH > 5; extracting at least one lipophilic impurity from said fermentation broth; acidulating said fermentation broth to form an aqueous medium of pH
Abstract:
A system comprising: (a) a transmitter adapted to provide an audio signal output comprising an embedded data element imperceptible to a human being of normal auditory acuity when said audio signal output is played through speakers wherein said embedded data element is embedded using phase modulation; and (b) an audio receiver adapted to receive said audio signal output and extract said embedded data element and respond to at least a portion of the data in said embedded data element.
Abstract:
An integrated plant comprising: (a) one or more lignocellulose processing units producing one or more sugar streams and one or more lignin streams; (b) one or more lignin-processing units processing one or more of said lignin streams into a lignin product; and (c) one or more sugar processing units processing one or more of said sugar streams into a sugar product; (d) at least one transfer mechanism transferring one or more of said sugar stream(s) to one or more of said sugar processing units over a distance of 5 km or less; and (e) at least one transfer mechanism transferring said lignin stream from one or more of said lignocellulose processing units to one or more of said lignin processing units over a distance of 5 km or less.
Abstract:
Lignin compositions, products produced from them or containing them, methods to produce them, spinning methods, methods to convert lignin to a conversion product and conversion products produced by the methods are described.
Abstract:
Processes for converting lignocellulose to feedstock and downstream products are disclosed. The processes may include acid treatment of lignocellulose to produce a fermentation feedstock. In various instances, the processes include recovery or recycling of acid, such as recovery of hydrochloric acid from concentrated and/or dilute streams. Downstream products may include acrylic acid-based products such as diapers, paper and paper-based products, ethanol, biofuels such as biodiesel and fuel additives, and detergents.
Abstract:
A method comprising: (a) enzymatically processing an O-acetylhomoserine (OAHS) fermentation liquor to produce L-methionine and an acetate source; (b) separating at least a portion of said L-methionine from at least a fraction of said acetate source to form separated L-methionine and a residual liquor comprising an acetate-source; and (c) recovering at least a portion of said acetate source from said residual liquor as recovered acetate.

Abstract:
A nano-sized photon collector (NSPC) comprising: (a) a nano-sized crystalline semiconducting particle, at least a portion of which is not insulated; (b) a quantum dot photon collector particle(PC); and(c) an insulating coating comprising silica on at least a portion of said PC.
Abstract:
A method comprising: (a) providing a partially processed sucrose crop product containing at least 2% optionally at least 5% of the sucrose content of said crop at harvest on a dry solids basis, cellulose and lignin; (b) hydrolyzing said partially processed crop product with HCl to produce an acid hydrolyzate stream and a lignin stream; and (c) de-acidifying said hydrolyzate stream to produce a de-acidified sugar solution and an HCl recovery stream. Additional, methods, systems and sugar mixtures are also disclosed.
Abstract:
The invention describes a propeller-less turbine for the conversion of linear flow energy to rotary power. The turbine is based on a plurality of hollow elements, with at least one element having a tapered helical structure. Inlet and outlet define a chamber through which air or water may flow, energy from the flow being delivered to the body of the turbine and thus allowing for highly efficient conversion of linear to rotary energy.
