“…The use of this method with positive results has been reported in screening of pentose-fermenting yeasts [9], and xylitol and D-arabitol producing strains [16,17]. It is worth noting that in the three reports mentioned, the percentages of effective yeast strains were 1.5, 2.12, and 2.6%, respectively, while in the present work it was 1%.…”

Polyalcohol arabitol can be used in the food and pharmaceutical industries as a natural sweetener, a dental caries reducer, and texturing agent. Environmental samples were screened to isolate effective yeast producers of arabitol. The most promising isolate 27RL-4, obtained from raspberry leaves, was identified genetically and biochemically as Candida parapsilosis. It secreted 10.42– 10.72 g l-1 of product from 20 g l-1 of L-arabinose with a yield of 0.51 - 0.53 g g-1 at 28°C and a rotational speed of 150 rpm. Batch cultures showed that optimal pH value for arabitol production was 5.5. High yields and productivities of arabitol were obtained during incubation of the yeast at 200 rpm, or at 32°C, but the concentrations of the polyol did not exceed 10 g l-1. In modified medium, with reduced amounts of nitrogen compounds and pH 5.5-6.5, lower yeast biomass produced a similar concentration of arabitol, suggesting higher efficiency of yeast cells. This strain also produced arabitol from glucose, with much lower yields. The search for new strains able to successfully produce arabitol is important for allowing the utilization of sugars abundant in plant biomass.

“…This model in 5-L reactor would benefit the optimizing control of d-glucose fermentation in industrial production of d-arabitol. The maximum yield of d-arabitol by Z. rouxii JM-C46, 93.48 ± 2.79 g/L (measured in 96 h), was higher than reported yeasts producing d-arabitol, such as K. ohmeri NH-9 [19], M. reukaufii AJ14787 [12] and Z. rouxii NRRL 27624 [2]. Among them, the strain Z. rouxii NRRL Y-27624 can produce 83.4 ± 1.1 g d-arabitol from 175 g d-glucose per liter in 240 h with the volumetric productivity of 0.348 g/L h. Here, the highest volumetric productivity, 1.143 g/L h, was measured in 72 h by repeated-batch fermentation.…”

A new strain producing high yield of D-arabitol was isolated from hyperosmotic environments and the ITS rDNA sequencing analysis revealed it as Zygosaccharomyces rouxii. In addition, using a pH control and repeated-batch fermentation strategy in a 5-L reactor, the maximum yield and the highest volumetric productivity of D-arabitol were 93.48 ± 2.79 g/L and 1.143 g/L h, respectively. Volumetric productivity was successfully improved from 0.86 to 1.143 g/L h, which was increased by 32.9 % after 72 h of fermentation. Z. rouxii JM-C46 has potential to be used for D-arabitol and xylitol production from glucose via D-arabitol route.

“…This could be a problem, because an increase of sugar alcohols would reduce the yield of ethanol. The increased production of sugar alcohols by relatively high temperature has also been reported in other yeast [5,32]. Sugar alcohols are known as compatible solutes that protect organisms from stresses [4].…”

Yeasts that ferment both hexose and pentose are important for cost-effective ethanol production. We found that the soil yeast strain NY7122 isolated from a blueberry field in Tsukuba (East Japan) could ferment both hexose and pentose (D-xylose and L-arabinose). NY7122 was closely related to Candida subhashii on the basis of the results of molecular identification using the sequence in the D1/D2 domains of 26S rDNA and 5.8S-internal transcribed spacer region. NY7122 produced at least 7.40 and 3.86 g l⁻¹ ethanol from 20 g l⁻¹ D-xylose and L-arabinose within 24 h. NY7122 could produce ethanol from pentose and hexose sugars at 37°C. The highest ethanol productivity of NY7122 was achieved under a low pH condition (pH 3.5). Fermentation of mixed sugars (50 g l⁻¹ glucose, 20 g l⁻¹ D-xylose, and 10 g l⁻¹ L-arabinose) resulted in a maximum ethanol concentration of 27.3 g l⁻¹ for the NY7122 strain versus 25.1 g l⁻¹ for Scheffersomyces stipitis. This is the first study to report that Candida sp. NY7122 from a soil environment could produce ethanol from both D-xylose and L-arabinose.
