Formation of esters of yeast. I. The production of ethyl acetate by standing surface cultures of Hansenula anomala.
It has been known for some time (Hansen, 1891) that organic esters may be produced in small amounts by some microorganisms as byproducts in their utilization of organic compounds. A detailed review of the literature to 1922 on aroma producing microorganisms is given by Omelianski (1923). The taxonomy of the yeast genus Hansenula, which contains species producing the greatest yields of ester, is...
متن کاملA Case of Fungal Arthritis Caused by Hansenula Anomala
Hansenula anomala (H. anomaly) is part of the normal flora in the alimentary tract and throat. It has been reported to be an organism causing opportunistic infections in immunocompromised patients. However, cases of fungal arthritis caused by H. anomala are rare. We encountered a case of H. anomala arthritis in a 70-year-old man who was treated with an empirical antibiotic treatment and surgery...
متن کاملProduction of sophorolipid biosurfactant by Pichia anomala.
Biosurfactant production by Pichia anomala PY1, a thermotorelant strain isolated from fermented food, was examined as grown in media containing various carbon and nitrogen sources. The optimal conditions for biosurfactant production included 4% soybean oil as carbon source at pH 5.5 at 30 degrees C for 7 d. Under these conditions, the surface tension of the medium decreased to 28 mN/m with oil ...
متن کاملPyridine nucleotidenitrate reductase from Hansenula anomala a nitrate reducing yeast.
The recent elucidation of the enzyme systems involved in nitrate reduction in Neurospora crassa (Evans and Nason, 1952; Nason and Evans, 1953); Bacillus pumilis (Taniguchi et al., 1953); Escherichia coli (Taniguchi et al., 1956; Nicholas and Nason, 1955) and higher plants (Evans and Nason, 1953), has renewed interest in the general problem of nitrate reduction and nitrate assimilation in microo...
متن کاملArabinose induces pellicle formation by Vibrio fischeri.
Biofilms are multicellular communities of bacteria attached to a surface and embedded in a protective matrix. In many cases, the signals that induce biofilm formation are unknown. Here, we report that biofilm formation by the marine bacterium Vibrio fischeri can be induced by the addition of arabinose to LBS (Luria-Bertani-salt), a tryptone-based medium. Growth of cells in the presence of 0.2% ...
