Asymmetric reduction of substituted acetophenones using once Rhodotorula glutinis cells immobilized

Taşkın, Mehmet Fatih; Kurbanoğlu, Namudar İzzet (ELSEVIER SCI LTD, 2010)

The asymmetric reductions of acetophenone and its analogues using once immobilized Rhodotorula glutinis cells were studied. The performance and reaction parameters of the immobilized cells were also investigated and it was ...
Continuous production of (S)-1-phenylethanol by immobilized cells of Rhodotorula glutinis with a specially designed process

Kurbanoğlu, Namudar İzzet; Taşkın, Mehmet Fatih (PERGAMON-ELSEVIER SCIENCE LTD, 2010)

A specially designed process for the continuous production of a chiral alcohol by immobilized Rhodotorula glutinis was prepared and is reported. The performance of the process with immobilized cells was also investigated. ...
Highly enantioselective reduction of acetophenone by locally isolated Alternaria alternata using ram horn peptone

Kurbanoğlu, Namudar İzzet; Taşkın, Mehmet Fatih (PERGAMON-ELSEVIER SCIENCE LTD, 2007)

Enantiomerically pure compounds are important building blocks in the synthesis of natural products. In this study, the reduction of acetophenone to the (S)-isomer of 1-phenylalcohol with a high enantiomeric excess (ee) by ...
Production of (R)-1-phenylethanols Through Bioreduction of Acetophenones by a New Fungus Isolate Trichothecium roseum

Taşkın, Mehmet Fatih; Kurbanoğlu, Namudar İzzet; Kılıç, Harun (WILEY, 2010)

A total of 120 fungal strains were isolated from soil samples and evaluated in the bioreduction of substituted acetophenones to the corresponding (R)-alcohols. Among these strains, isolate Trichothecium roseum EBK-18 was ...
Production of (R)-3 '-fluorophenylethan-1-ol by Trichothecium roseum isolate in a laboratory scale bioreactor

Taşkın, Mehmet Fatih; Kurbanoğlu, Namudar İzzet (JOHN WILEY & SONS LTD, 2009)

CONCLUSION: An important chiral intermediate for the pharmaceutical industry using T. roseum EBK-11 in submerged culture containing RHP from waste material was produced up to gram scale with excellent ee (99%). In this ...
Production of (S)-(-)-1-(1'-Napthyl) Ethanol by Rhodotorula glutinis Isolate Using Ram Horn Peptone

Kurbanoğlu, Namudar İzzet; Taşkın, Mehmet Fatih; Kılıç, Harun (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2008)

The bioreduction of 1-acetonaphthone 1 by locally isolated Rhodotorula glutinis strains using ram horn peptone (RHP) gave (S)-(-)-1-(1'-naphthyl) ethanol ( 2), an important pharmaceutical intermediate. R. glutinis strains ...
Total production of (R)-3,5-bistrifluoromethylphenyl ethanol by asymmetric reduction of 3,5-bis(trifluoromethyl)-acetophenone in the submerged culture of Penicillium expansum isolate

Taşkın, Mehmet Fatih; Kurbanoğlu, Namudar İzzet (PERGAMON-ELSEVIER SCIENCE LTD, 2009)

A total of 82 fungal isolates were screened for their ability to reduce 3,5-bis(trifluoromethyl)-acetophenone 1. Penicillium expansum was found to successfully reduce ketone I in the submerged culture. A second screening ...
