 LACTIC ACID FERMENTATION definition
<biochemistry> A type of fermentation carried out by lactic acid bacteria in which sugar (for example lactose, glucose, pentose) are converted either entirely (or almost entirely) to lactic acid (homolactic fermentation) or to a mixture of lactic acid and other products (heterolactic fermentation).

 Virtanen, Artturi Ilmari
As a chemistry instructor at the University of Helsinki (1924-39), where he became professor of biochemistry (1939-48), Virtanen studied the fermentation processes that spoil stores of silage.
Virtanen was also a professor of biochemistry at the Helsinki University of Technology (1931-39) and director of Finland's Biochemical Research Institute, Helsinki, from 1931.
Knowing that the fermentation product, lactic acid, increases the acidity of the silage to a point at which destructive fermentation ceases, he developed a procedure (known by his initials, AIV) for adding dilute hydrochloric or sulfuric acid to newly stored silage, thereby increasing the acidity of the fodder beyond that point.

 Two Centuries of Catalysis
With the centenary of the discovery of cell-free fermentation (Buchner, 1897) we are entering the second century of scientific biochemistry, based on the idea that life processes are no more than chemistry, uncomplicated by notions of vitalism.
Resolutely opposed to any idea that enzymes might be proteins, he also refused to believe that cell-free fermentation mimicked the process in the cell.
We now know, of course, that not all biological catalysis is mediated by proteins, but the existence of catalytic RNA hardly alters the fact that the great majority of enzymes are proteins.

 Stoichiometric network constraints on xylose metabolism by recombinant Saccharomyces cerevisiae
To understand the differences between glucose and engineered xylose metabolic networks, we performed a flux balance analysis (FBA) and calculated extreme pathways using a stoichiometric model that describes the biochemistry of yeast cell growth.
Fermentation results were largely consistent with in silico phenotypes based on calculated extreme pathways, which displayed several phases of metabolic phenotype with respect to oxygen availability from anaerobic to aerobic conditions.
Engineering of xylose metabolism in Saccharomyces cerevisiae has focused on introducing genes for the initial xylose assimilation steps from Pichia stipitis, a xylose-fermenting yeast, into S. cerevisiae, a yeast raditionally used in ethanol production from hexose.

Barker was exposed to van Niel’s theories about the chemistry of the overall methane fermentation when he spent summers at the Hopkins Marine Station while a graduate student in chemistry at Stanford and later as a postdoctoral fellow with van Niel.
Barker’s contributions are today so much a part of the fundamental fabric of modern biochemistry and microbiology that it is easy for younger scientists to overlook the modest and gentle man who made them.
Barker’s commitment to a lifelong study of the chemical activities of microorganisms was consolidated during a year’s study (1935-36) with van Niel’s mentor A. Kluyver in the Delft Microbiology Laboratory, which was supported by a fellowship from the Rockefeller Foundation.
