Abstract: The present invention relates to the isolation of novel glucan particles but also to mannoprotein from natural sources such as yeast cell walls, novel isolation methods, and the use of products thereof.

Abstract: The invention relates to a novel process for the preparation of (1R,4S)- or (1S,4R)-1-amino-4-(hydroxymethyl)-2-cyclopentene of the formulae 1

Abstract: The invention relates to a novel process for the preparation of (1R,4S)- or (1S,4R)-1-amino-4-(hydroxymethyl)-2-cyclopentene of the formulae and/or of (1S,4R)- or (1R,4S)-amino alcohol derivatives of the general formulae and to novel microorganisms which are able to utilize a cyclopentene derivative of the general formula as sole nitrogen source, as sole carbon source or as sole carbon and nitrogen source. The invention further relates to enzyme extracts and enzymes having N-acetylamino-alcohol hydrolase activity obtainable from these microorganisms.

Abstract: Microorganism which can utilize an N-protected proline derivative of general formula (I) in the form of the racemate or one of its optically active isomers, R1 meaning —(CH2)2—COOH or, optionally substituted in each case, C1-C4 alkoxy, aryl or aryloxy, and R2 meaning hydrogen or hydroxy, as the only nitrogen, only carbon or only carbon and nitrogen source. These microorganisms can be used in a process for producing N-protected cyclic or aliphatic D-amino acid derivatives of general formulae (II) and (V), A together with —N— and —CH— and R3, R4 and R5 having the given meanings.

Abstract: Two shafts each containing a gear wheel or gear are each journalled in two bearing bushes. Each bearing bush is mounted in an end or closure bush laterally inserted into a housing. The end bushes each comprise a collar at the axially inner end thereof which overlaps the inner end of the associated bearing bush. The end bushes are each secured to a respective holder or retaining ring which is received in a countersink formed in the housing and which is firmly held intermediate the housing and a cover member. Consequently, the bearing bushes may be separated from the associated shafts by axially displacing the shafts within the housing after removal of the cover members.

Abstract: A balance beam having a short arm carrying a weighing pan and a long arm whose weight counteracts the torque exerted by the pan on the beam has a longitudinal edge extending over both arms and notched at uniform intervals. A rider weight is movable along the beam for alternative engagement with the notches in the two arms, the spacing of the notches being greater than in an otherwise equivalent balance having notches in the long arm only, and manufacturing tolerances in the making of the notches thus have a smaller effect on the precision of the balance.
