1. Evaluation of yeast culture and direct-fed microbial on gut histology and serum components of broilers challenged with suboptimal diets under heat stress
ABSTRACT. The use of antibiotics in feed for growth promotion has been restricted in many countries, thus it is of interest to investigate potential alternatives for enhancing growth performance in birds. An experiment was carried out to evaluate the concurrent use of prebiotic and probiotic on gut histology and some blood chemicals of broiler chickens dur

2. Influência da idade do lodo na colmatação das membranas em um biorreator à membrana tratando esgoto sanitário
RESUMO O presente estudo avaliou o efeito da idade do lodo (θc) no potencial incrustante do licor misto em um biorreator à membrana (BRM) tratando esgoto sanitário. Tal avaliação foi conduzida em BRM construído em escala de bancada, com volume útil de 15 L, operado por 420 dias na modalidade de batelada sequencial. Durante o período experimental, for

3. Effect of Non-Starch Polysaccharide (NSP) of Wheat and Barley Supplemented with Exogenous Enzyme Blend on Growth Performance, Gut Microbial, Pancreatic Enzyme Activities, Expression of Glucose Transporter (SGLT1) and Mucin Producer (MUC2) Genes of Broiler Chickens
ABSTRACT The experiment was carried out in a completely randomized design (CRD) with 625 broiler chicks (Ross 308) for 5 repetitions (25 birds per each replicated) on the 5 treatments diet. Treatments included two different types of cereal grains (wheat, and barley) with or without an enzyme supplementation along with a corn-based diet as control group. The

4. Colleters in Chamaecrista (L.) Moench sect. Chamaecrista and sect. Caliciopsis (Leguminosae-Caesalpinioideae): anatomy and taxonomic implications
ABSTRACT The genus Chamaecrista contains ca. 330 species organized into six sections, of which section Chamaecrista is the second largest (ca.75 species) distributed among six series, while the section Caliciopsis contains only two species. Colleters have been described in the genus Chamaecrista and they show potential taxonomic and phylogenetic significance

5. Polysaccharide-based biomaterials with antimicrobial and antioxidant properties
Active packaging is one of the responses to the recent food-borne microbial outbreaks and to the consumer’s demand for high quality food and for packaging that is more advanced and creative than what is currently offered. Moreover, with the recent increase in ecological awareness associated with the dramatic decrease in fossil resources, research has turne

6. Microbiological, technological and therapeutic properties of kefir: a natural probiotic beverage
Kefir is a fermented milk beverage produced by the action of bacteria and yeasts that exist in symbiotic association in kefir grains. The artisanal production of the kefir is based on the tradition of the peoples of Caucasus, which has spread to other parts of the world, from the late 19th century, and nowadays integrates its nutritional and therapeutic indi

7. Heparan sulphate, its derivatives and analogues share structural characteristics that can be exploited, particularly in inhibiting microbial attachment
Heparan sulphate (HS) and the related polysaccharide, heparin, exhibit conformational and charge arrangement properties, which provide a degree of redundancy allowing several seemingly distinct sequences to exhibit the same activity. This can also be mimicked by other sulphated polysaccharides, both in overall effect and in the details of interactions and st

8. Produção e aplicação da levana de Bacillus subtilis natto em filmes isolados para liberação cólon-específica de fármacos
Este trabalho teve o objetivo de apresentar a levana como candidata na elaboração de um novo material polimérico conjuntamente com o Eudragit FS 30D® e RS 30D®. Filmes cólon-específicos, a base de polímeros metacrilatados, possuem maior controle na liberação do ativo quando aditivados de um prebiótico; melhorando a terapêutica de patologias colô

9. Sustentabilidade e qualidade do solo em propriedades de cana-de-açúcar orgânica e convencional / Sustentability and soil quality in organic and conventional sugarcane establishments
Soil quality evaluation is an important strategy, as it allows producers to focus agriculture techniques to constantly develop and maintain adequate, selfsustainable productions equilibrium. This study evaluated rural activities environmental impact by the system APOIA-NovoRural, as well as the influence of different sugarcane production systems on soil qual

10. Avaliação da genotoxicidade das xantanas produzidas pelas cepas 06 e 24 de Xanthomonas campestris pv pruni através do ensaio cometa e teste de micronúcleos.
Among the vast number of types of polysaccharides produced in nature, by plants, algae, and bacteria, xanthan is the one of the few that has functional properties leading to a broad spectrum of uses as well as commercial production in large quantities. It is the second microbial polysaccharide to be developed for an economically process, and it has continued

11. Especificidade em associações alga/bactéria vinculadas aos carbidratos excretados por três espécies fitoplanctônicas de um reservatório tropical eutrófico do Estado de São Paulo (Barra Bonita).
The release of carbohydrates by phytoplankton has been extensively studied because of its ecological significance. Bacterioplankton is a group of organisms that is able to use extracellular phytoplanktonic carbohydrates, as many authors have demonstrated. The aim of this thesis was to identify specific associations algae/bacteria in the planktonic environmen

12. Decomposição de Staurastrum iversenii Neygaard var. americanum: efeitos da qualidade do recurso, da disponibilidade de oxigênio e da temperatura.
In this work the decomposition aspects of the Staurastrum iversenii Nygaard var. americanum phytoplankton species, isolated from the Barra Bonita Reservoir (22 degrees 29 minutes S e 48 degrees 34 minutes W), were approached; as resource of the decomposition were used: cells (ruptured and whole) and polysaccharide of higher and lower molecular masses. Were a
