Abstract: Compositions having at least one compound which inhibits the formation of Hemipteran stylet sheaths and/or degrades hemipteran style sheaths that have already been formed, and thus deters or blocks hemipteran insects from feeding on plants, especially agriculturally important plants and methods of use of such compositions are described. Such compositions can be applied onto plants by spraying, dripping, or other methods and/or can be applied to the soil for uptake by the roots. These compositions and methods prevent and/or reduce the transmission of vascular associated diseases (caused by hemipteran vector-borne pathogens) to plants.

Abstract: Described herein are processes to produce polygalacturonic acids from pectin containing products, said process involving (a) optionally washing pectin containing products, (b) optionally injecting dry steam into pectin containing products [and maintaining a temperature of about 140° to about 160° C. under pressure at about 40 to about 60 psi for a time period of between about 0.5 to about 3 minutes, (c) optionally heating pectin containing products to above about 70° C. to about 95° C. or optionally cooling to less than about 10° C.

Abstract: Enzymes accumulated in plant cell walls serve diverse physiological functions including metabolism, polysaccharide structure modification, and molecular communication in interactions with other organisms. Pectin methylesterases are economically important enzymes for their impact on quality and processing properties of fruit and vegetable food products. We have now purified TT-PME to homogeneity from sweet orange finisher pulp and determined the complete corresponding nucleic acid sequence. Purified TT-PME was observed by SDS-PAGE as two doublet bands with molecular masses of approximately 46,000 Da and 56,000 Da. Direct Edman sequencing from these proteins showed a common N-terminal peptide. De novo sequencing of eight TT-PME tryptic peptides determined by MALDI-TOF/TOF mass spectrometry provided additional internal sequences. TT-PME did not correspond to any previously reported Citrus spp. PME sequence.

Abstract: A process for the enzymatic oxidation of alcohols to aldehydes in a continuous reaction series is disclosed utilizing crude cellular methanol oxidase and catalase produced by an acceptable organism such as those selected from the genera of Pichia, Hansenula, Candida and Torulopsis. The process maintains a steady-state aldehyde concentration whereby enzyme activity is promoted. In particular, the process has two reactors operating in series continuously producing a fermenter effluent containing growing, intact yeast cells at a cell concentration of about 0.5 to about 3% by weight of the effluent by continuous culture of the cells on a methanol carbon source, continuously introducing the effluent from the first reactor to the second reactor, adding an alcohol feed at about 0.2-10% w/w and oxygen to the second reactor, maintaining a steady-state aldehyde concentration in the reaction mixture, the concentration of residual alcohol being about 0.

Abstract: A polyvalent cation crosslinked pectin fiber composition is composed of a calcium sensitive low methoxyl pectin with a degree of esterification (DE) of less than 15% or calcium sensitive amidated pectin having a DE of less than 50% where the pectin is polyvalent cation crosslinkable and has an average molecular weight (MW) having an upper limit of 200,000 and a lower limit of 5000. This pectin is useful in making wound dressings for topical applications.

Abstract: A process for the enzymatic oxidation of alcohols to aldehydes in a continuous reaction series is disclosed utilizing crude cellular methanol oxidase and catalase produced by an acceptable organism. The process maintains a steady-state aldehyde concentration whereby enzyme activity is promoted and side reactions are eliminated.In particular, the process has two reactors operating in series continuously producing a fermenter effluent containing growing, intact Candida boidinii cells at a cell concentration of about 0.5 to about 3% by weight of the effluent by continuous culture of the cells on a methanol carbon source, continuously introducing the effluent from the first reactor to the second reactor, adding an alcohol feed at about 0.2-10% w/w and oxygen to the second reactor, maintaining a steady-state aldehyde and alcohol concentration in the reaction mixture, the concentration of residual alcohol being about 0.1-9% w/w by controlling the rates of introduction of effluent and alcohol feed.

Abstract: The present invention provides medical devices comprised of ionically crosslinked polymer, especially, stents, catheter or cannula components, plugs, and constrictors. The medical devices of the present invention are prepared by treatment of ionically crosslinkable polymer compositions with crosslinking ion compositions to provide ionically crosslinked materials.An important aspect of the present invention is that these medical devices can be disintegrated in-vivo at a desired time through the exposure of the medical device to a chemical trigger which generally is described as an agent that acts to displace the crosslinking ion in the ionically crosslinked material through binding or simple replacement with a non-crosslinking ion.
