Title: Recombinant yeasts containing the dna sequences coding for xylose reductase-and xylitol dehydrogenase enzymes
Inventor: HALLBORN JOHAN
IPC: C12P7/18
Filed: 1991-04-08
Abstract: This invention relates to recombinant-DNA-technology. Specifically this invention relates to new recombinant yeast strains transformed with xylose reductase and/or xylitol dehydrogenase enzyme genes. A  yeast strain transformed with the xylose reduc-tase gene is capable of reducing xylose to xylitol and consequently of producing xylitol in vivo. If both of these genes are trans-formed into a yeast strain, the resultant strain is capable of producing ethanol on xylose containing medium during fermentation. Further, the said new yeast strains are capable of expressing the said two enzymes. Xylose reductase produced by these strains can be used in an enzymatic process for the production of xylitol in vitro.

Abstract: EXTRUDED CONNECTOR STRIP               Abstract of the Disclosure An extruded connector strip is described and more particularly, but not exclusively, for use as a weatherstrip connector.   The connector strip has an elongated  attachment  body which  has  a  flat  rear attachment wall from which a pair of spaced-apart parallel flexible spacer ribs extend outwardly and sloped towards opposed elongated end edges thereof. An adhesive transfer tape is securable to at least one or more flat portions of the rear attachment wall  to  secure  the  connector  strip  against  an object.    The  flexible  spacer  ribs  permit  the attachment  body  to  be  located  over  a  connecting surface of an object to which it is intended to be secured while preventing the outer adhesive surface of the transfer tape from contacting the connecting surface until pressure is applied to the attachment body which causes the spacer ribs to flex and the outer adhesive surface of the tape to contact the connecting surface to adhere thereto.

The composition comprises a phosphatidylcholine lung surfactant, a phosphatidylethanolamine, and cholesterol in proportions such that the composition is in lamellar form at or below a first temperature and in non-lamellar form at a second temperature which is higher than the first temperature. A preferred phosphatidylcholine lung surfactant for use in this invention is dipalmitoyl phosphatidylcholine (DPPC), which is known to be the major lipid constituent of natural mammalian lung surfactant, and a preferred phosphatidylethanolamine is dioleoyl phosphatidylethanolamine (DOPE). In particular embodiments, the composition is in lamellar form at about room temperature (25  DEG C), and in non-lamellar form at a temperature in the range of about 30 to 37  DEG C, which is at or below normal human body temperature (37  DEG C). The composition may also include one or more therapeutic peptides or other pharmaceutical agents. The synthetic lung surfactant may be used to treat a mammal for respiratory distress syndrome caused by an insufficiency of natural lung surfactant.
