desarrollo de una fuente proteica en cuba levadura Torula candida utilis
Revista Cubana de Ciencia Agrícola (Cuba) Vol.39, 2015Co-Authors: P LezcanoAbstract:Se analiza el desarrollo que ha tenido la produccion en gran escala de la levadura Torula (Candida utilis) en Cuba desde 1964 con la primera planta construida en el pais a partir de miel final como fuente de energia hasta el momento actual. Se presentan los resultados de su composicion y riqueza especialmente en cuanto a aminoacidos y vitaminas del complejo B. Se ofrecen los principales valores del comportamiento productivo en las diferentes categorias porcinas al sustituir la harina de soya como fuente de proteinas y se analiza tambien el cuestionamiento que sobre la Torula ha tenido el costo de produccion en comparacion con la soya, determinado principalmente por la miel final invertida y los gastos energeticos para producir una tonelada de levadura seca. Finalmente se analizan las ultimas alternativas de producir Torula a partir de las vinazas de destileria que se genera diariamente en grandes cantidades y constituye un contaminante ambiental de gran importancia y que necesariamente tienen que tener algun tratamiento .Se plantea la necesidad de reiniciar investigaciones en los animales y medir el impacto tecnico-economico y ambiental de esta nueva forma de producir levadura Torula.

Soybean meal substitution by Torula yeast (Candida utilis) grown on vinasses in pelleted diets for fattening rabbits
Cuban Journal of Agricultural Science, 2013Co-Authors: Abel Ortiz, W. Motta Ferreira, M. Anchieta Ramirez, F. Moraes Hosken, P LezcanoAbstract:Four diets were evaluated in fattening rabbits of the White New Zealand breed. A completely randomized design with four treatments and 16 replications was used. Treatments consisted of the inclusion in the feed of 0, 5, 10 and 15% of Torula yeast ( Candida utilis ) grown on vinasses from alcohol distillery, as soybean meal substitution. After 41 fattening days, the viability (75.00; 87.50; 93.75 and 87.50 %, respectively), live weight at slaughter (2204; 2233, 2193 and 2228 g/animal), average daily gain (37.49; 38.18; 37.40 and 38.03 g/animal), consumption (4912; 4985; 4946 and 4944 g/animal) and conversion (3.24; 3.20; 3.25 and 3.19) did not differ significantly between treatments. The same occurred with the weight and carcass yield, skin, liver, heart and kidneys. It is concluded that diets for fattening rabbits including Torula yeast grown on vinasses from alcohol distillery, as partial or total substitute of soybean meal, do not provoke significant changes in the bio-productive indicators of the rabbits at the end of fattening neither on weight and carcass yield and edible organs after slaughter. Key words: rabbits, feeding, Torula yeast

Evaluation of Torula yeast (Candida utilis) grown on distillery vinasse for broilers
Cuban Journal of Agricultural Science, 2013Co-Authors: P Lezcano, Magaly HerreraAbstract:The inclusion of Torula yeast ( Candida utilis ) grown on distillery vinasse as alternative protein source in the diet was evaluated. Its effect was determined on the productive performance and carcass yield of broilers. Animals were housed in metallic cages (1000 birds, from 1 to 42 d of age), according to a completely randomized design. The experimental treatments consisted of a control diet (maize-soybean) and three diets including 10, 20 and 30% of vinasse Torula yeast, with ten replications each. Feed consumption showed an increase (P < 0.001) with the inclusion of yeast being more marked with 20 and 30%, which influenced negatively on feed conversion, while 10% did not differ from the control and allowed the highest (P < 0.001) live weight gain (1 830 g vs. 1 803). Live weight and carcass yield with 30% Torula yeast was lower (P < 0.01) than with 10%, although not differing from the control group and that of 20%. It is considered that up to 20% of vinasse Torula yeast can be used in diets for broilers, as partial replacement of soybean cake meal, without affecting the productive performance and carcass yield.

chemical composition and nutritive value of Torula yeast candida utilis grown on distiller s vinasse for poultry feeding
Cuban Journal of Agricultural Science, 2011Co-Authors: Barbara Rodriguez, L M Mora, D Oliveira, A C C Euler, L Larav, P LezcanoAbstract:The object of this work was to determine dry matter (DM), crude protein (CP), ether extract (EE), crude fiber (CF), ash, metabolizable energy and retention of nutrients of the Torula yeast from distiller’s vinasse, for its use in poultry feeding. The Torula yeast from vinasse had average value of 43.24 % CPB, 1.60 % CF, 1.20 % EE, and 7.15% ash. There were average values of apparent metabolizable energy (AME) of 2811 kcal/kg, corrected by the nitrogen balance (AMEn) of 2362 kcal/kg and coefficient of metabolization of the energy (CMGE) of 58 %. The apparent retention of the dry matter was 65.20 %, and of 53.81 % for nitrogen and of 63.46 % for total phosphorus. It was concluded that it is feasible to use distiller’s vinasse as basic substrate for the production of Torula yeast, by not having differences in the chemical composition and the nutritional value of this protein source; thus, it can be used in poultry feeding. Key words: yeast, metabolizable energy, retention of nutrients, broiler chickens.

Mineral composition of Torula yeast (Candida utilis), grown on distiller's vinasse
2011Co-Authors: Barbara Rodriguez, P Lezcano, A. A. Canela, W. F. Motta, A C C EulerAbstract:A neutron activation analysis was conducted to determine the minerals in Torula yeast grown on distiller’s vinasse. The mineral material and total phosphorous were determined according to AOAC (1995). The presence of 23 elements of the periodic table was determined in the analysis by neutron activation. Potassium (K), calcium (Ca), chloride (Cl), manganese (Mg), iron (Fe) and sodium (Na) were those of largest concentration. It was proved that there was high content of mineral material (7.15 %) and total phosphorous (1.61%) in the yeast. The mineral composition of the Torula yeast from vinasse showed higher values for Ca, K, Fe and Zn than those reported by the NRC (1998) in soybean meal and Torula yeast.

Universidade Estadual de Londrina, 2015Co-Authors: Fabio Morais Hosken, Walter Motta Ferreira, Felipe Norberto Alves Ferreira, Clarice Speridiao Silva Neta, Katiuscia Cristina Das Neves Mota, Abel Ortiz MilánAbstract:The aim of this study was to assess the nutritional value of diets that contain Torula yeast in rabbits and agoutis and the influence of Torula yeast on the apparent digestibility of the nutrients. In the first experiment, 32 New Zealand White rabbits were fed diets with four different levels (0%, 5%, 10%, and 15%) of Torula yeast that was substituted for soybean meal. The experimental design was completely randomized with four treatments and eight repetitions. The digestibility coefficients (DC) of dry matter (DM; DCDM), crude protein (DCCP), neutral detergent fiber (DDNDF), ether extract (DCEE), and gross energy (DCGE), as well as the mean daily consumption (MDC), were calculated (MDC: 113.98, 113.96, 113.22, and 115.07 g animal-1; DCDM: 71.04%, 69.98%, 67.79%, and 74.08%; DCCP: 80.17%, 79.55%, 75.10%, and 78.47%; DCND: 66.85%, 65.50%, 63.31%, and 70.12%; DCEE: 77.83%, 76.46%, 78.36%, and 82.07%; and DCGE: 71.04%, 69.98%, 68.37%, and 73.82%). No significant effects (P > 0.05) were found on the MDC or the DCs for the different yeast levels, and the inclusion of Torula up to 15% did not affect diet digestibility. The digestible energy (DE) (kcal kg-1 DM-1) of a diet with 15% Torula yeast was calculated as 2,870.52 with the methodology proposed by Matterson (MMT) and 2,870.89 when corrected by the methodology proposed by Villamide (MVD). Linear regression estimated the DE (kcal kg-1 DM-1) as 2,805.22. The digestible protein (DP; g kg-1 DM-1) of a diet with 15% Torula yeast was calculated as 182.6 with the MTT method and 190.9 with the MVD correction. Linear regression estimated the DP (g kg-1 DM-1) as 293.0. In the second experiment, 20 agoutis were divided into two treatment groups: a control group and one given a base diet containing 30% Torula yeast. The experimental design was completely randomized with two treatments and ten replications. The DCDM, DCCP, DCNDF, DCEE, DCGE, and the DCs of organic matter (DCOM) and mineral matter (DCMM), as well as the MDC, were calculated (MDC: 84.48 and 90.48 g animal-1, DCDM: 67.62% and 67.06%, DCCP: 71.12% and 68.l9%, DCNDF: 72.70% and 69.89%, DCOM: 70.52% and 20.27%, and DCMM: 36.27% and 33.16%), and no significant differences (P > 0.05) were found. The DCEE (63.39% and 48.04%) and DCGE (68.00% and 63.73%) results differed significantly (P < 0.05). The DE (kcal kg-1 DM-1) of 30% Torula yeast in the diet was calculated as 1,714.22 with the MMT method and 1,663.69 with the MVD correction.

It was concluded that it is feasible to use distiller’s vinasse as basic substrate for the production of Torula yeast, by not having differences in the chemical composition and the nutritional value of this protein source; thus, it can be used in poultry feeding. Key words: yeast, metabolizable energy, retention of nutrients, broiler chickens.

Mineral composition of Torula yeast (Candida utilis), grown on distiller's vinasse
2011Co-Authors: Barbara Rodriguez, P Lezcano, A. A. Canela, W. F. Motta, A C C EulerAbstract:A neutron activation analysis was conducted to determine the minerals in Torula yeast grown on distiller’s vinasse. The mineral material and total phosphorous were determined according to AOAC (1995). The presence of 23 elements of the periodic table was determined in the analysis by neutron activation. Potassium (K), calcium (Ca), chloride (Cl), manganese (Mg), iron (Fe) and sodium (Na) were those of largest concentration. It was proved that there was high content of mineral material (7.15 %) and total phosphorous (1.61%) in the yeast. The mineral composition of the Torula yeast from vinasse showed higher values for Ca, K, Fe and Zn than those reported by the NRC (1998) in soybean meal and Torula yeast.

Torula yeast (Candida utilis)-derived glucosylceramide contributes to dermal elasticity in vitro.
Journal of food biochemistry, 2019Co-Authors: Shoko Fukunaga, Sayori Wada, Mika Yamashita, Mayuko Morita, Wataru Aoi, Yuji Naito, Akane HigashiAbstract:Glucosylceramide (GlcCer) is derived from several plants, such as rice, maize, and wheat, and has been reported to retain moisture by functioning as a barrier between the epidermis and the environment. However, there is insufficient research on the effect of GlcCer on dermal elasticity and wrinkles. In this study, we investigated the effects of Torula yeast extract and Torula yeast-derived GlcCer on dermal elasticity. We measured cell proliferation, collagen production, and collagen gel contraction using human dermal fibroblasts. Torula yeast extract and Torula yeast-derived GlcCer increased dermal fibroblast proliferation and collagen production. Collagen gel contraction was promoted by Torula yeast extract and Torula yeast-derived GlcCer. These results indicate that GlcCer may affect dermal elasticity. Torula yeast extract and Torula yeast-derived GlcCer may contribute to the maintenance of dermal elasticity. PRACTICAL APPLICATIONS: In this study, we found that Torula yeast-derived glucosylceramide (GlcCer) has an additional function of improving dermal elasticity. With improved elasticity, skin becomes more resilient, thus preventing wrinkles. GlcCer has already been used in cosmetic products to retain skin moisture. Therefore, Torula yeast-derived GlcCer can be expected to have several cosmetic applications.

Effect of Torula Yeast (Candida utilis)-Derived Glucosylceramide on Skin Dryness and Other Skin Conditions in Winter
Journal of nutritional science and vitaminology, 2018Co-Authors: Shoko Fukunaga, Sayori Wada, Wataru Aoi, Toshiya Sato, Masahide Hamaguchi, Akane HigashiAbstract:Glucosylceramide (GlcCer) is present in foods such as barley, corn, and wheat flour. GlcCer derived from different foods has differences in its physiological effects, depending on the sphingoid backbone and constituent fatty acids. In this study, we investigated the moisturizing and skin conditioning effects of GlcCer derived from Torula yeast (Candida utilis) in healthy human subjects. The participants were randomly distributed in a crossover, double-blind comparative manner. Seventeen volunteers were orally administered both 1.8 mg/d of GlcCer derived from Torula yeast and a placebo for 4 wk. Before and after oral administration, transepidermal water loss (TEWL) was measured and the objective skin condition observation and a questionnaire on skin condition were conducted. The primary endpoint was TEWL; secondary endpoints included the objective and subjective skin conditions. The change in TEWL over the study period on the forearm was -0.97±0.48 and -1.26±0.46 g/m2•h in the placebo and GlcCer groups, respectively, with significantly lower (p=0.01) TEWL observed in the GlcCer group. Brown spots increased in the placebo group but significantly decreased in the GlcCer group (p=0.04). Although chapped skin worsened in the placebo group, it significantly improved in the GlcCer group (p=0.04). The use of Torula yeast-derived GlcCer as a functional cosmeceutical food is a viable option to ameliorate skin conditions, including improvement in skin barrier function, reduction of brown spots, and fixation of chapped skin.
