Lipase of Mucor pusillus.
Lipase of Mucor pusillus NRRL 2543 was recovered with ammonium sulfate precipitation, gel filtration on Sephadex G-75, and anion-exchange chromatography on diethylaminoethyl-Sephadex A-50. Maximal glycerol ester hydrolase (lipase) activity was observed at pH 5.0 to 5.5 and 50 C when trioctanoin and olive oil were used as substrates. The enzyme also showed esterase activity; it hydrolyzed, with ...
متن کاملblubber of Cape fur seals Arctocephalus pusillus pusillus off the Eastern Cape coast of South Africa
The concentration of heavy metals (Cd, Cu, Pb, Ni and Zn) and organochlorine contaminants (PCBs, DDT, DDE and DDD) in the blubber of 12 adult male Cape fur seals, Arctocephalus pusillus pusillus, inadvertently caught in trawl nets off the Eastern Cape coast of South Africa during commercial fishing operations between May 1993 and October 1994, was investigated. The median and range of concentra...
متن کاملPartial Purification of Mucor pusillus Intracellular Proteases.
The intracellular protease extracted from the freeze-dried mycelia obtained after the growth of Mucor pusillus at 30 degrees C in corn steep liquor medium was chromatographed on DEAE-A50. Some characteristics of the protease fractions obtained after ion-exchange chromatography were determined and compared with those of the extracellular proteases reported previously. The mycelia were found to c...
متن کاملEffect of Potamogeton pusillus on Water Quality and Plankton CommunityEffect of Potamogeton pusillus on Water Quality and Plankton Community
In closed aquatic environments like ponds or lakes, water bloom caused by eutrophication has severely damaged aquatic ecosystems. Some previous studies suggested that submerged macrophytes contribute to the development of aquatic ecosystems and water purification. Although water purification and lake ecosystem restoration using submerged macrophytes have been greatly studied, their specific mec...
متن کاملAromaticine, a sesquiterpene lactone from Amblyopappus pusillus
AROMATICINE (SYSTEMATIC NAME: 4a,8-dimethyl-3-methyl-ene-3,3a,4,4a,7a,8,9,9a-octa-hydro-azuleno[6,5-b]furan-2,5-dione), C(15)H(18)O(3), is a natural lactone isolated from Amblyopappus pusillus. The mol-ecular structure and conformation agree with the results of Romo, Joseph-Nathan & Díaz [(1964 ▶). Tetra-hedron, 20, 79-85]. The fused-ring system contains a seven-membered ring in a twist-boat co...
