Analysis of the secondary compounds produced by Saccharomyces cerevisiae and wild yeast strains during the production of "cachaça" BJM
Dato,Maria Cecília Fachine; Pizauro Júnior,João Martins; Mutton,Márcia Justino Rossini.
The aim of this study is to compare the composition of "cachaças" produced in 10 fermentation cycles by Saccharomyces cerevisiae (Sc) and wild yeast strains [Pichia silvicola (Ps), Pichia anomala 1 (Pa1), Pichia anomala 2 (Pa2) and Dekkera bruxelensis (Db)], isolated from distilleries in Jaboticabal - SP, Brazil. The secondary components of the heart fraction were determined by gas chromatography. The levels of secondary components were influenced by the wine pH, which varied among yeast strains. S. cerevisiae showed slightly more secondary components, whereas wild strains produced more higher alcohols. Wild yeast strains were shown to be adequate for the production of a high quality "cachaça".

Apple wine processing with different nitrogen contents BABT
Alberti,Aline; Vieira,Renato Giovanetti; Drilleau,Jean Françoise; Wosiacki,Gilvan; Nogueira,Alessandro.
The aim of this work was to evaluate the nitrogen content in different varieties of apple musts and to study the effect of different nitrogen concentrations in apple wine fermentation. The average total nitrogen content in 51 different apples juices was 155.81 mg/L, with 86.28 % of the values above 100 mg/L. The apple must with 59.0, 122.0 and 163.0 mg/L of total nitrogen content showed the maximum population of 2.05x 10(7); 4.42 x 10(7) and 8.66 x 10(7) cell/mL, respectively. Therefore, the maximum fermentation rates were dependent on the initial nitrogen level, corresponding to 1.4, 5.1 and 9.2 g/L.day, respectively. The nitrogen content in the apple musts was an important factor of growth and fermentation velocity.

Athelia (Sclerotium) rolfsii in Allium sativum: potential biocontrol agents and their effects on plant metabolites Anais da ABC (AABC)
CAVALCANTI,VYTÓRIA P.; ARAÚJO,NEILTON A.F.; SCHWANESTRADA,KÁTIA R.F.; PASQUAL,MOACIR; DÓRIA,JOYCE.
Abstract Garlic (Allium sativum L.) plays an important role in popular culture due to its dietary and medicinal uses. It is also used to produce a wide range of pharmacologically interesting molecules. Several pathogens affect garlic plants, especially Athelia (Sclerotium) rolfsii, a fungus that is widespread and causes large economic losses. It causes direct damage to crops and leads to plant stress, which induces secondary metabolite production in plants. The use of microorganisms as biocontrol agents may induce the production of beneficial metabolites in plants that will protect it and promote resistance to pathogen attack. In addition to suppressing disease, biological control agents may have elicitor effects that could induce an increase in the...

Biosurfactants production by yeasts using soybean oil and glycerol as low cost substrate BJM
Accorsini,Fábio Raphael; Mutton,Márcia Justino Rossini; Lemos,Eliana Gertrudes Macedo; Benincasa,Maria.
Biosurfactants are bioactive agents that can be produced by many different microorganisms. Among those, special attention is given to yeasts, since they can produce many types of biosurfactants in large scale, using several kinds of substrates, justifying its use for industrial production of those products. For this production to be economically viable, the use of residual carbon sources is recommended. The present study isolated yeasts from soil contaminated with petroleum oil hydrocarbons and assessed their capacity for producing biosurfactants in low cost substrates. From a microbial consortium enriched, seven yeasts were isolated, all showing potential for producing biosurfactants in soybean oil. The isolate LBPF 3, characterized as Candida antarctica,...

Candida albicans Clinical Isolates from a Southwest Brazilian Tertiary Hospital Exhibit MFS-mediated Azole Resistance Profile Anais da ABC (AABC)
PINTO,ANA CAROLINA C.; ROCHA,DEBORA A.S.; MORAES,DANIEL C. DE; JUNQUEIRA,MARIA L.; FERREIRA-PEREIRA,ANTONIO.
Abstract: Candida albicans is the most frequent fungal species that causes infections in humans. Fluconazole is the main antifungal used to treat Candida infections, and its prolonged and indiscriminate use for the last decades are the most established causes which originated resistant strains. Fungal drug resistance is associated to alterations in ERG11 gene and overexpression of multidrug resistance (MDR) transporters belonging to two families: ATP-binding cassette (ABC) and Major Facilitator Superfamily (MFS). To evaluate the role of MFS transporters in azoles resistance of C. albicans clinical strains, this study aimed to analyze four Candida albicans clinical isolates from the University Hospital in Juiz de Fora (Minas Gerais/Brazil), selected in our...

Changes in trehalose content of baker's yeast as affected by octanoic acid Scientia Agricola
Gutierrez,L.E..
Octanoic acid inhibited ethanolic fermentation by Saccharomyces cerevisiae (bakers yeast) and the trehalose accumulation, however did not affect the endogenous degradation of trehalose. This inhibition may be explained by the binding of octanoic acid to hexokinase or other proteins of plasma membrane because they are not necessary for endogenous fermentation. The degradation of trehalose may be due to an activation of trehalase.

Chlorine dioxide against bacteria and yeasts from the alcoholic fermentation BJM
Meneghin,Silvana Perissatto; Reis,Fabricia Cristina; Almeida,Paulo Garcia de; Ceccato-Antonini,Sandra Regina.
The ethanol production in Brazil is carried out by fed-batch or continuous process with cell recycle, in such way that bacterial contaminants are also recycled and may be troublesome due to the substrate competition. Addition of sulphuric acid when inoculum cells are washed can control the bacterial growth or alternatively biocides are used. This work aimed to verify the effect of chlorine dioxide, a well-known biocide for bacterial decontamination of water and equipments, against contaminant bacteria (Bacillus subtilis, Lactobacillus plantarum, Lactobacillus fermentum and Leuconostoc mesenteroides) from alcoholic fermentation, through the method of minimum inhibitory concentration (MIC), as well as its effect on the industrial yeast inoculum. Lower MIC...

Comparison of two lipid extraction methods produced by yeast in cheese whey BABT
Castanha,Rodrigo Fernandes; Morais,Lilia Aparecida Salgado de; Mariano,Adriano Pinto; Monteiro,Regina Teresa Rosim.
This work aimed to evaluate nine strains of yeast, previously identified as good producers of lipids in honey medium, for selecting the most suitable strain for the production of lipids in cheese whey medium and compared two well known extraction methods of lipids from the culture medium. The highest yield of total lipids was 1.27 g.L-1 produced by Cryptococcus laurentii 11. A comparison was made between the two culture media: cheese whey and liquid YEPG, and two lipid extraction methods: Bligh and Dyer and Folch et al. for C. laurentii. The experiments were performed with 2² full factorial design using two factors and two levels. Lipid content was higher in cheese whey and there was no difference in the extraction methods statistically. The method of...

Cross effects of the strain of dietary Saccharomyces cerevisiae and rearing conditions on the onset of intestinal microbiota and digestive enzymes in rainbow trout, Onchorhynchus mykiss, fry ArchiMer
Wache, Yann; Auffray, Francoise; Gatesoupe, Joel; Zambonino, Jose-luis; Gayet, Vincent; Labbe, Laurent; Quentel, C.
Two strains of Saccharomyces cerevisiae were tested as probiotics for rainbow trout fry, during the first month of feeding. Each strain was introduced into separate diets, at the rate of 106 CFU g− 1 and their effects were compared with those of a control diet. Two rearing conditions were simultaneously compared, to test the adaptability of the probiotic treatment. From start feeding onwards, the water supply came from either spring or river, resulting in two different temperature ranges, 11¿11.5 and 7¿8 °C respectively. Growth and development were optimal in spring water, while some delay was observed with colder river water. A slight but significant increase in mortality was also observed in the river group. In all groups, the counts of...
