    Change of Lipid Composition of Mucor miehei as a Function of Cultivation Temperature (2000)
    Springer
    Chemistry of natural compounds 36 (2000), S. 349-351 
    Details
    ISSN: 1573-8388
    Keywords: Mucor miehei ; lipids ; fatty acids ; desaturases
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Lipids of the thermophilic fungus Mucor miehei,strain UzLT-3, cultivated at 26 and 42 C are studied. The lipids of this strain contain isomeric 18:2 (9,12) and (6,9) fatty acids and polyene acids - and -18:3, which are uncharacteristic of thermophilic fungi. Cultivation at 26°C increases the fraction of phospholipids (PL), glycolipids (GL), and isomeric 18:3 fatty acids in the total lipids. It is hypothesized that the liquid-crystalline state of the membranes of this strain at reduced temperature are due to activation of desaturases δ 12 and δ 15 and possibly δ 6 , which are present in the fungus and participate in the biosynthesis of unsaturated acyl lipids.

    Preparation and Application of Immobilized Cells from the Fungus Mucor miehei (2000)
    Springer
    Chemistry of natural compounds 36 (2000), S. 402-403 
    Details
    ISSN: 1573-8388
    Keywords: Mucor miehei ; immobilized cells ; polymeric support ; bioreactor ; wastewaters ; continuous processes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A laboratory bioreactor was developed for functionalizing immobilized cells of the mycelial fungusMucor miehei.The ability to use the cells to purify wastewaters from the oil-refining industry is demonstrated. With proper operation of the reactor, immobilized cells (1 g) can purify 〉100 l of wastewater containing 0.10-0.15% of lipid-like substances.

    Coupling of iminodiacetic acid with amino acid derivatives in solution and solid phase (2000)
    Springer
    International journal of peptide research and therapeutics 7 (2000), S. 331-345 
    Details
    ISSN: 1573-3904
    Keywords: ACP (65-74) ; coupling reagents ; HATU ; HBTU ; HSTU ; iminodiacetic acid ; infrared studies ; Kyotorphin ; Leucine Enkephalin ; solution and solid phase peptide synthesis ; TCFH ; TFFH
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary The IR studies for the preactivation step of N-protected iminodiacetic acid with different coupling reagents (TCFH, TFFH, HATU, HBTU, HSTU) were reported here and showed the formation of an anhydride as an active intermediate in case of TCFH and TFFH. The formation of a mixture of an anhydride and an active ester (-OBt,-OAt or-OSu) were observed for HBTU, HATU or HSTU coupling reagent. Dependent on the coupling conditions, acylation of N-protected iminodiacetic acid with amino acid ester or amide derivatives in solution phase gave monoor di-substituted iminodiacetic acid derivatives. Coupling of N-protected iminodiacetic acid with an amino acid or peptide attached to a solid support (PAL-PEG-PS or Wang resin) gave only the monosubstituted iminodiacetic acid derivatives.
