A process for producing glass fiber-reinforced thermoplastic resin pellets, which comprises a step of drawing out glass fiber strands from the inside of glass fiber rolls and introducing them into a resin impregnation die, a step of supplying a molten thermoplastic resin into the resin impregnation die and impregnating the glass fiber strands with the thermoplastic resin, a step of drawing out the glass fiber strands impregnated with the thermoplastic resin from the resin impregnation die and cooling and solidifying the thermoplastic resin to obtain a linear molded product, and a step of cutting the molded product into a predetermined length, wherein as the glass fibers, glass fiber strands drawn out from rolls, each roll obtained by bundling monofilaments having a diameter of from 6 to 25 &#x3bc;m and winding them so that the inner diameter will be from 18 to 50 cm, are used.

Glass fiber-reinforced thermoplastic resin pellets and their production process

A long-fiber-reinforced thermoplastic resin sheet comprises short strands, each of which has a width of from 0.2 to 5 mm and a length of from 10 to 150 mm and is made of a unidirectionally long-fiber-reinforced thermoplastic resin. The short strands are oriented at random and are fixed together at intersections thereof. The long-fiber-reinforced thermoplastic resin sheet has a basis weight of from 30 to 500 g/mand is provided with openings therein. The long-fiber-reinforced thermoplastic resin sheet can be produced by evenly spreading and piling up short strands of substantially circular or elliptical sections, and subjecting the short strands to pressureless hot-melt adhesion or to hot-melt compression bonding under pressure such that the sheet has a basis weight of from 30 to 500 g/mand is provided with openings therein. The short strands of the substantially circular or elliptical sections have an average diameter of from 0.1 to 1.5 mm and an average length of from 10 to 150 mm, and are made of a unidirectionally long-fiber-reinforced thermoplastic resin.

CHOLESTEROL DEHYDROGENASE, COPROSTAN-3-ONE DEHYDROGENASE AND 4-CHOLESTEN-3-ONE DEHYDROGENASE, COMPOSITIONS CONTAINING THE DEHYDROGENASES, AND METHOD FOR REDUCING AMOUNT OF CHOLESTEROL USING THE COMPOSITIONS

An enzymatic process is presented for reducing the cholesterol level of foods and feeds by converting the cholesterol therein to coprostanol which has a very low intestinal tract absorbability. Cholesterol in meat, egg, milk, seafood and cooked processed foods containing the same, or feeds for animals, poultry, and pisiculture can be reduced by the sequential action of three enzymes isolated from a eubacterium: cholesterol dehydrogenase, 4-cholesten-3-one dehydrogenase and coprostan-3-one dehydrogenase.

The present invention provides a recombinant DNA comprised of a vector DNA and a DNA fragment containing a gene coding for .gamma.-glutamyl transpeptidase derived from Bacillus subtilis. The invention also provides a process for producing .gamma.-glutamyl transpeptidase, which comprises culturing in a culture medium a microorganism belonging to the genus Bacillus which is carrying recombinant DNA comprised of a vector DNA and DNA fragment which contains a gene coding for .gamma.-glutamyl transpeptidase derived from the genus Bacillus, accumulating .gamma.-glutamyl transpeptidase in the culture, and recovering .gamma.-glutamyl transpeptidase therefrom.

A process for producing L-lysine is disclosed in which a recombinant vector, a DNA fragment of which contains a gene involved in the synthesis of dihydropicolinic acid synthetase, is used to transform a microorganism of the genus Corynebacterium or Brevibacterium. The transformant is then cultured in a medium which supports the accumulation of L-lysine. Subsequently the L-lysine is recovered from the culture broth.
