  • Publication number: 20120135466
    Abstract: The combination of a Pseudomonas saccharophila G4-forming amylase (PS4) variant and a pullulanase advantageously can catalyze at a high temperature saccharification to produce an increased amount of maltotetraose, which can be used downstream in a process of producing a maltotetraose syrup. In one embodiment, a thermostable PS4 variant supplement with a pullulanase is provided that can produce about 40% to about 60% by weight maltotetraose, based on total saccharide content.

  • Publication number: 20120120893
    Abstract: A method of resource allocation for use in a wireless network is disclosed. A network coloring decision to assign a plurality of resource blocks to a plurality of cells within the wireless network is triggered upon occurrence of a network event. A network coloring is performed by assigning each cell of the plurality of cells a resource block from the plurality of resource blocks. An effect of interference among adjacent cells with a same resource block assignment is reduced as measured by a network performance metric related to a number of resource block assignment conflicts over the plurality of cells.

  • Publication number: 20120045812
    Abstract: Embodiments of the present disclosure relate to a process for producing isoprene from a starch substrate by saccharification and/or fermentation. The saccharification is effectively catalyzed by a glucoamylase at a pH in the range of 5.0 to 8.0. At a pH of 6.0 or above, the glucoamylase possesses at least 50% activity relative to its maximum activity. The saccharification and fermentation may be performed as a simultaneous saccharification and fermentation (SSF) process.

  • Publication number: 20110165288
    Abstract: The present invention relates to a process for producing a rice protein concentrate from a rice substrate comprising, enzymatically hydrolyzing a rice substrate with an enzyme having granular starch hydrolyzing (GSH) activity and a second starch hydrolyzing enzyme at a temperature at or below 72° C. and at a pH of about 3.0 to 6.5 to obtain a solubilized starch fraction and a residue fraction which includes insoluble protein, and separating the solubilized starch fraction from the residue to obtain a rice protein concentrate. The rice protein concentrate may be used in animal feed and human food formulations.

  • Publication number: 20100331175
    Abstract: A selective hydrogenation catalyst, with alumina as carrier, and palladium as active component that distributed on the surface of the carrier in an egg-shell form, characterized in that: provided that the catalyst is weighed 100%, it comprises 0.2-0.5 wt % active component Pd, 2-8 wt % aids lanthanum and/or cerium, and 2-8 wt % alkaline earth metal. The specific surface area of the catalyst is 70-150 m2/g, the pore volume is 0.3-0.6 ml/g, and the crystal form of the carrier may be ? form or ?, ? mixed form mainly composed of ? form. The catalyst is suitable for the selective hydrogenation of medium or low distillate oil, especially for the first stage selective hydrogenation of pyrolysis gasoline. The catalyst has good hydrogenation performance, and can keep good hydrogenation activity and stability especially under the condition that the feed contains a small quantity of water, and the content of colloid, arsenic, and diolefin is higher.

  • Patent number: 5966966
    Abstract: A freeze concentration method separates the nucleation and the growth processes at least to the extent necessary to enable nucleation and crystal growth to occur at different temperatures. Nucleation, however, is triggered by a sonicator, i.e., ultrasonic radiation. This provides excellent control of the process since the variables of the input sonic energy are adjusted easily. Most importantly, the use of ultrasound permits nucleation at low supercooling. The consequences of this are: an inexpensive plain--as opposed to the more complex and expensive scraped-surface--heat exchanger can be used since the coolant temperature is only slightly lower than that of the solution, preventing ice scaling in the heat exchanger; the higher coolant temperature leads to savings also in the operation costs. In addition ultrasonic nucleators are easily scaled-up to treating the large-volume effluents from industrial plants. The only way to scale-up scraped-surface nucleators is by using multiple nucleators in parallel.
