Synthesis and evaluation of pseudolipids to characterize lipase selectivities

Enzymes of the Genus Aspergillus

“…The enzyme from A. niger is available Flavor development in food and dairy products Detergent additive for cleaning commercially and has been extensively studied (Akita et at., 1986;Andree et at., 1980;Gerlach et at., 1988;Hoq et at., 1985;Kalo, 1988;Linefield et at., 1984;Macrae and Hammond, 1985;Sonnet and Antonia, 1988).…”

Microbial Enzymes and Biotechnology

“…The positional specificity which is an important characteristic in regard to some industrial and analytical uses of lipases has been determined in the course of the characterization of most of the lipases listed as has the substrate specificity of many of the enzymes (Okumura et ai., 1976;Joshi & Mathur, 1985;Joshi & Dhar, 1987). The selectivity of the lipases is most commonly studied using natural substrates for the enzymes but may also be tested conveniently by using pseudolipids as substrates (Sonnet & Antonia, 1988). niger, R. delemar, M. Miehei and H. lanuginosa appear to be attractive sources of 1,3-specific lipases while the lipases produced by G. candidum and P. cye/opium have been shown to be positionally unspecific.…”

Synthesis and lipase catalyzed hydrolysis of thiolesters of 2‐, 3‐ and 4‐methyl octanoic acids

“…(C7H~C=0) +. The required thiol for lc was obtained by converting 3-mercapto-l,2-propanediol to a mixture of the two acetonides and separating these by silica gel column chromatography (19).…”
