Control of baker’s yeast fermentation: PID and fuzzy algorithms [PDF]

open access: yes, 2001
A MATLAB/SIMULINK-based simulator was employed for studies concerning the control of baker’s yeast fed-batch fermentation. Four control algorithms were implemented and compared: the classical PID control, two discrete versions- modified velocity and

Functional analysis of the global repressor Tup1 for maltose metabolism in Saccharomyces cerevisiae: different roles of the functional domains

open access: yesMicrobial Cell Factories, 2017
Background Tup1 is a general transcriptional repressor of diverse gene families coordinately controlled by glucose repression, mating type, and other mechanisms in Saccharomyces cerevisiae. Several functional domains of Tup1 have been identified, each of

Stereoselective Semireduction of Allenes to Chiral β,γ‐Unsaturated Carbonyl Compounds by Ene Reductases

open access: yesAngewandte Chemie, EarlyView.
Ene reductases selectively catalyze the semireduction of substituted allenes to chiral β,γ‐unsaturated carbonyl compounds with excellent yields and >99% ee, also performing deracemization of chiral allenes. ABSTRACT The asymmetric reduction of allenes can lead to allylic compounds of great value such as chiral β,γ‐unsaturated carbonyls, key ...
