Performance of jundiá larvae, Rhamdia quelen, fed on probiotic supplemented diets Animal Sciences
Pinto, Vilson Borba; Costenaro-Ferreira, Cristiano; Oliveira, Paulo Leonardo Silva; Oliveira, Rodrigo Ribeiro Bezerra de; Piedras, Sérgio Renato Noguez; Pouey, Juvêncio Luis Osório Fernandes.
Since probiotics have proved to be a viable alternative to antibiotics as enhancers of animal growth, the performance, uniformity and mortality rates of the jundiá (Rhamdia quelen) larvae fed on diets with different probiotics were evaluated. Jundiá larvae, aged four days post hatching, were fed during 21 days with the following diets, in four replicates, namely, CO: control feed, without probiotics; PP: feed with Pichia pastoris; SB: feed with Saccharomyces boulardii; BT: feed with Bacillus cereus var. toyoi. Among the tested probiotic, Bacillus cereus var. toyoi had the best results due to the fact that the larvae were 25% heavier than CO at the end of the first week; the difference increased to 28% by the end of the trial. Further, BT also improved...

Effect of the trehalose levels on the screening of yeast as probiotic by in vivo and in vitro assays BJM
Martins,Flaviano S.; Miranda,Ieso C.; Rosa,Carlos A.; Nicoli,Jacques R.; Neves,Maria J..
Probiotics are viable defined microorganisms (bacteria or yeasts) that exert a beneficial effect on the health of the host when ingested in adequate amounts. Screening for such biotherapeutic agents is commonly performed by in vitro assays simulating gastrointestinal environment to determine the ability to survive in the digestive tract. In the present study, the possibility of extrapolation of data obtained in in vitro assays to in vivo conditions was studied using five Saccharomyces cerevisiae strains isolated from Brazilian Atlantic rain forest. Trehalose contents and survival after exposure to a combination of physiological stresses generally found in the gastrointestinal tract of humans were determined for the five yeasts and compared to the behavior...

Identification by PCR and evaluation of probiotic potential in yeast strains found in kefir samples in the city of Santa Maria, RS, Brazil Ciênc. Tecnol. Aliment.
CASSANEGO,Daniela; RICHARDS,Neila; VALENTE,Patricia; MAZUTTI,Marcio; RAMÍREZ-CASTRILLON,Maurício.
Abstract Kefir is a product elaborated from the symbiotic fermentation of different microorganisms. The Kluyveromyces and Saccharomyces genera are the major representatives of the yeasts found in kefir microbiota. The only pobiotic yeast commercialized as an oral medication, is the Saccharomyces boulardii. The present work involved the microbiological quality examination of six kefir samples in the city of Santa Maria/RS, the yeasts isolation present in the samples and the identification of them by PCR (Polymerase chain reaction). Then, their probiotic potential was evaluated by in vitro technique. After that, microbiological analysis confirmed that kefir samples were suitable for consumption once the microbiological quality was established. Nineteen yeast...

Probióticos e resposta imune Ciência Rural
Coppola,Mario de Menezes; Gil-Turnes,Carlos.
Os probióticos são bactérias que produzem efeitos benéficos no hospedeiro, usadas para prevenir e tratar doenças, como promotores de crescimento e como imunoestimulantes. Nesta revisão abordam-se as principais aplicações dos probióticos, com ênfase nas informações recentes sobre suas propriedades de modular a resposta imune.

Biological control of Mycosphaerella fragariae in strawberry culture Sci. Agrar.Paran. / SAP
Heling, Anderson Luis; Kuhn, Odair José; Stangarlin, José Renato.
The Mycosphaerella spot is one of the main foliar diseases of strawberry, degrating great leaf regions and reducing the photosynthetic area. Its control is mainly by the use of chemical fungicides, but, due the increasing demand for food free of pesticide, alternative control methods have been researched, such as biological control. This work aimed to evaluate the effect on strawberry plants, treated with the biological control agents Bacillus cereus, Saccharomyces boulardii and Saccharomyces cerevisiae, in the severity of Mycosphaerella fragariae, productivity and in the activity of β-1.3 glucanases, peroxidases and chitinases enzymes. It was verified that S. cerevisiae and B. cereus treatments were similar to fungicide for disease control. However, even...

Interference in quality of strawberry caused by the use of biological agents for disease control Sci. Agrar.Paran. / SAP
Heling, A. L.; Favorito, P. A.; Kuhn, O. J..
The strawberry is a fruit of great market acceptance and it is much appreciated throughout the world, besides being very important for small farmers, generating employment and income. Nevertheless, this crop is affected by various diseases that require control, so that producers eventually use chemical fungicides, which, besides contaminating soil and water, eventually contaminate the fruit. In an attempt to reduce the amount of pesticides used in the strawberry crop, a lot of research on biological control of diseases has been done. However, the biological control of diseases in strawberries should not interfere negatively in fruit quality. Thus, this study aimed to evaluate the acidity, pH and total soluble solids (ºBrix) of strawberries treated with...
