Abstract
Svrha rada je opisati proces malolaktičke ili jabučno-mliječne fermentacije (JMF) pri proizvodnji vina. Jabučno-mliječna fermentacija je dekarboksilacija L-malata u L-laktat u prisustvu bakterija mliječnih kiselina, posebice bakterija rodova Leuconostoc, Pediococcus i Lactobacillus. Njihov rast je ograničen hranidbenim i fizikalno-kemijskim čimbenicima kao što su temperatura, niski pH, te koncentracija etanola i sumporovog (IV) oksida. Jabučno-mliječna fermentacija se može odvijati nakon alkoholne fermentacije, ali i paralelno s istom. Unazad nekoliko desetljeća vinari su uočili njezinu važnost s obzirom da taj proces može utjecati na okus vina, deacidifikaciju (otkiseljavanje), te njegovu mikrobiološku stabilnost. Koristi se za proizvodnju kiselijih vina dobivenih iz grožđa uzgojenog u području s hladnom klimom koja često imaju nisku pH vrijednost. Glavni preduvjet za proizvodnju kvalitetnog vina je odabir dobrog bakterijskog soja koji ima odgovarajuće kvalitativne i tehnološke karakteristike.
Abstract (english)
The goal of the thesis was to describe the process of malolactic fermentation in wine production. Malolactic fermentation is decarboxylation of L-malate into L-lactate in the presence of lactic acid bacteria (LAB), mainly Leuconostoc, Pediococcus, and Lactobacillus. Their growth is limited by nutritional and physicochemical factors, such as storage temperature, low pH, and alcohol and suphur dioxide concentrations. Malolactic fermentation can take place after the alcoholic fermentation, but also simultaneously with it. Few decades ago, winemakers noticed its importance because the process can affect flavour, deacidification, and microbial stability of wine. It is used in production of wines produced from grapes grown in colder climates, which are often more acidic and have a low pH. The main prerequisite for the production of quality wine is a selection of a good bacterial strain with desirable qualitative and technological characteristics.
