Applications wine production

Electrocatalysis in oxidation has apparently first been shown for ascorbic acid oxidation by Prussian blue [60] and later by nickel hexacyanoferrate [61]. More valuable for analytical applications was the discovery in the early 1990s of the oxidation of sulfite [62] and thiosulfate [18, 63] at nickel [62, 63] and also ferric, indium, and cobalt [18] hexacyanoferrates. More recently electrocatalytic activity in thiosulfate oxidation was shown also for zinc [23] hexacyanoferrate. Prussian blue-modified electrodes allowed sulfite determination in wine products [64], which is important for the wine industry. 

The same chemical principles presented by the speakers on red (p. 59) and white table wine (p. 29) production are applicable to table wine production in the Interior Valley. Differences in the size of the winery operations and grape maturity are attributable to regional climatic conditions. With modern viticultural practices, the grapes grown for winemaking in this interior region now produce quality wines and they also comprise the largest volume of table wines produced in California. 

All of them are product and process dependent but generally an increased yield of product on the substrate [128] and an increased growth rate are common properties that S. cerevisiae is required to have in order to produce an efficient processes. More specific desired features are the high productivity of ethanol in brewing and wine making, of CO2 in baking, and minimization of overflow metabolism (ethanol and glycerol) and increased biomass yield on the substrate in applications where product formation is directly coupled to biomass.

Quantification of phenolic compounds in wine and during key stages in wine production is therefore an important quality control goal for the industry and several reports describing the application of NIR spectroscopy to this problem have been published.

Community initiatives focused on creating science learning experiences beyond the classroom. Community partnerships involved teachers and students working in association with local industry, in parks, on excursions or programs of visits, or with scientists. For example, a primary school worked in a new local wetlands park, the aim of which is to restore environmental conditions to be similar to those prior to European settlement. Secondary school students became involved in a wine production process in partnership with a local wine industry, in which they engaged in plant propagation and in chemical applications such as fermentation, microbiology, soil analysis, and weather studies.
