Title: Tower reactors for bioconversion of lignocellulosic material
Inventor: NGUYEN QUANG A
IPC: C12P7/10
Filed: 1997-06-09
Abstract: An apparatus for enzymatic hydrolysis and fermentation of pretreated lignocellulosic material, in the form of a tower bioreactor, having mixers to achieve intermittent mixing of the material. Precise mixing of the material is important for effective heat and mass transfer requirements without damaging or denaturing the enzymes or fermenting microorganisms. The pretreated material, generally in the form of a slurry, is pumped through the bioreactor, either upwards or downwards, and is mixed periodically as it passes through the mixing zones where the mixers are located. For a thin slurry, alternate mixing can be achieved by a pumping loop which also serves as a heat transfer device. Additional heat transfer takes place through the reactor heat transfer jackets.

Title: Methods, polypeptides, nucleotide sequence of xor-6, a vitamin d-like receptor from xenopus
Inventor: EVANS RONALD M
IPC: C12Q1/02
Filed: 1996-01-16
Abstract: The inventions disclosed are new members of the steroid receptor superfamily of receptors of which a representative member has been designated XOR-6. The receptors are responsive to hydroxy, mercapto or aminobenzoates and are expressed in Xenopus leavis embryos. XOR-6 is most closely related to the vitamin D3 receptor. The amino acid sequences are about 73 % identical in the DNA-binding domains and about 42 % identical in the ligand binding domain. Like the vitamin D3 receptor, XOR-6 has an extended D region between the DNA and ligand binding domains. The region amino-terminal to the XOR-6 DNA-binding domain is extremely acidic which may influence its ability to activate genes. Southern blots show that XOR-6 related sequences are present in other vertebrates including humans. Also disclosed are nucleotide sequences encoding the XOR-6 receptor, constructs and cells containing sane, and probes derived from the XOR-6 sequence. Hydroxy, mercapto and aminobenzoates modulate the transcription of the invention receptors.

IPC: G06F17/30
Filed: 1996-07-11
Abstract: A method, apparatus and computer program product for reducing the data transmitted over an external communication link (35) from a first application (20) resident in a first computer (6) to a second application (10) resident in a second computer (5). The method, apparatus and computer program product include storing a data stream from the first application to be provided to the second application in response to a request from the second application in a cache resident in the first computer to create a server base cache entry and in a cache resident in the second computer to create a client base cache entry. Requests from the second application are interrogated to determine if a client base cache entry corresponding to the interrogated request exists and to determine if a server base cache entry corresponding to the interrogated request exists. The response data stream is intercepted prior to transmission of the response on the external communication link and compared to the server base cache entry to provide difference data corresponding to the difference between the intercepted response and the server base cache entry. The difference data is sent over the external communication link (35) and acquired by the second computer which reconstructs the response data stream by combining the client base cache entry with the difference data to create a response data stream which is provided to the second application.
