(four.72 g/L) [15].Foods 2021, 10,13 ofNo significant differences took spot inside the final concentration of succinic acid (around three g/L) among the industrial strains, despite the fact that the S. cerevisiae manage showed a reduced final concentration of around 50 . Laktia showed the highest pyruvic acid production, as much as 0.17 g/L, even VBIT-4 In Vivo Though Concerto and Levulia showed reduce concentrations than S. cerevisiae (0.13 g/L) [14]. 5.4. Acetic Acid L. thermotolerans is frequently a lower producer of acetic acid than the Saccharomyces genus [2,7]. Nevertheless, L. thermotolerans possesses a strain variability of up to 50 in acetic acid production [2,46]. Slight Ethyl Vanillate Epigenetic Reader Domain variations happen to be reported within the final concentration of acetic acid for sequential fermentations involving the Laktia, Concerto, and Levulia strains. The acetic acid concentration varied from 0.ten to 0.13 g/L, whilst the S. cerevisiae control showed drastically greater concentrations that varied from 23 to 41 greater than the L. thermotolerans sequential fermentations [15]. Surprisingly, sequential fermentations involving the Levulia L. thermotolerans strain developed 0.29 g/L of acetic acid, although Concerto and Laktia fermentations created 40 additional acetic acid without the need of substantial variations in between them; the S. cerevisiae control made the lowest final concentration in acetic acid, approximately 50 less than the Levulia manage [14]. 5.five. Total Sulfur Dioxide Levulia showed the lowest final concentration in total SO2 of 0.5 mg/L in sequential fermentations, although the S. cerevisiae handle showed a concentration of up to 13.three mg/L (96 greater) [14]. This impact may be related towards the low production of acetaldehyde and pyruvic acid in the strain. Concerto and Laktia showed decrease values than the S. cerevisiae handle by 66 and 74 , respectively. Another study reported that Concerto, Levulia, and Laktia create reduced concentrations of total sulfur dioxide compared to the S. cerevisiae handle by 65 , 61 , and 48 , respectively [15]. The S. cerevisiae control showed a final total sulfur dioxide concentration of 23 mg/L. Though in distinct order, the distinct research agree that sequential fermentations involving commercial L. thermotolerans strains lessen the final concentration of SO2 . This effect is of great interest for the production of wines with low concentrations of SO2 which are highly appreciated by some shoppers. five.six. Aroma Compounds The industrial L. thermotolerans strains (Levulia, Concerto, and Laktia) developed greater concentrations in total esters and reduced fatty acids than the S. cerevisiae handle [14]. Even though all L. thermotolerans strains made greater total esters than the S. cerevisiae handle, there have been significant variations in between them, as Levulia made 30 a lot more esters than the S. cerevisiae control, when Concerto and Laktia developed 71 and 75 much more, respectively [15]. Concerto was the highest producer in sequential fermentations of ethyl acetate, isoamyl acetate, and 2-phenylethyl acetate, when Laktia was the highest producer of ethyl lactate [14]. A different study also observed the commercial L. thermotolerans strains to produce larger concentrations of esters than the S. cerevisiae handle, though with bigger variations between Laktia and Concerto [16]. The study reported Laktia to create, in pure 1 L fermentations, 40 extra esters than the S. cerevisiae control, though Concerto only created 20 additional. The study highlighted Concerto producing significantly less ethyl acetate than Laktia by ap.
