Conditions of acetic acid producing by Brettanomyces yeast
Vestnik MGTU, 2018 Brettanomyces yeast has found their application in brewing (Lambic and Guezze style). Acetic acid obtained during fermentation by Brettanomyces yeast participates in the synthesis of ethers responsible for the taste and aroma component of the beverage ...

Low frequency aeration of pig slurry affects slurry characteristics and emissions of greenhouse gases and ammonia [PDF]
, 2017 Low frequency aeration of slurries may reduce ammonia (NH3) and methane (CH4) emissions without increasing nitrous oxide (N2O) emissions. The aim of this study was to quantify this potential reduction and to establish the underlying mechanisms.

Real‐Time Biomass Estimation in High‐Density Yeast Fermentations Using Soft Sensor Modeling
Biotechnology and Bioengineering, EarlyView.Accurate biomass measurements, both offline and online, are essential to improve prediction and control in yeast fermentation. This study develops regression‐based predictive models to correlate offline measurements (Dry Cell Weight and OD600 from a spectrophotometer) with online OD860 probe signals to provide accurate real‐time biomass estimations and

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors
Biotechnology and Bioengineering, EarlyView.ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Cereal Chemistry, EarlyView.ABSTRACT Background and Objectives The response of bread systems to ingredient enrichment varies depending on flour composition and matrix structure. This study investigated the impact of white garlic (WG) and black garlic (BG) enrichment (1%–7%) on the technological properties, composition, antioxidants, and sensory characteristics of refined white ...

Chemistry – A European Journal, EarlyView.This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

Aeration, tillage effects on [PDF]
, 2002 Few land management practices have the potential to impact upon soil aeration as directly or rapidly as tillage. Indeed, often, the reason for performing tillage is to modify or improve soil physical properties including aeration. The problems associated

Chemistry – A European Journal, EarlyView.Organo‐functionalized molecular molybdenum sulfides were synthesized using bidentate N‐donor ligands and investigated as light‐driven homogeneous hydrogen evolution reaction (HER) catalysts. Trends observed in the HER activity of these catalysts were elucidated by combining photophysical, electrochemical and computational studies.
