| Foram utilizados 44 leitões, desmamados aos 21 dias de idade, alimentados com cinco dietas (T1 – dieta basal; T2 – dieta basal + antibiótico; T3 – dieta basal + probiótico; T4 – dieta basal + prebiótico; T5 – dieta basal + simbiótico) e abatidos em três idades diferentes (dia do desmame, 7 e 14 dias pós-desmame). Logo após o abate, foi colhido um seguimento do intestino delgado para análise das atividades enzimáticas. Foram coletadas amostras de sangue dos leitões nos mesmos momentos pós-desmame para a análise do quadro hematológico. Os resultados demonstraram que os produtos adicionados na dieta não alteraram as atividades das enzimas de mucosa, porém foi observado aumento (p<0,05) nas atividades específicas da sacarase e maltase nos leitões que... |

| Resumen La fusariosis vascular del garbanzo (Cicer arietinum L.) aumenta debido a la dificultad para controlarla. El control químico disminuye la biodiversidad y contamina el ambiente, por lo cual se deben desarrollar medidas sustentables para limitar la enfermedad. Por lo tanto, el objetivo de este estudio fue determinar el potencial de cepas bacterianas y fúngicas, nativas de Sinaloa, como agentes biocontrol de esta enfermedad en plantas de garbanzo cultivadas en invernadero. La hipótesis fue que las cepas bacterianas y fúngicas nativas son una alternativa para controlar de la fusariosis vascular del garbanzo porque inhiben Fusarium oxysporum f. sp. ciceris. La inhibición de las cepas de control biológico se evaluó sobre el crecimiento radial de Fusarium... |

| RESUMEN La formación de biopelículas es un proceso importante para las comunidades bacterianas marinas debido a que este mecanismo favorece la adaptación a variaciones en las condiciones ambientales. El objetivo de este estudio fue evaluar la formación de biopelículas de las bacterias aisladas de sedimentos marinos en condiciones in vitro. Para esto se realizaron ensayos de cuantificación de biopelículas usando dos métodos, cristal violeta y reducción del colorante XTT; además se evaluó la viabilidad de las bacterias mediante la tinción Live/Dead. Posteriormente las cepas evaluadas fueron identificadas usando el marcador 16S ARN. Los resultados mostraron que los aislados pertenecen al género Bacillus todos en diferentes rangos fueron capaces de formar... |

| Feather waste is generated in large amounts as a by-product of commercial poultry processing. This residue is almost pure keratin, which is not easily degradable by common proteolytic enzymes. Eight strains of Bacillus, isolated from decomposing feathers were tested for the hydrolysis of feather wastes in the laboratory. Among these strains, Bacillus cereus KB043 was the best feather degrading organism when grown on basal medium containing 1% hen feather as sole source of carbon and nitrogen. It caused 78.16 ± 0.4 % degradation with a significant release of soluble protein (1206.15 ± 14.7 µg mL-1) and cysteine (20.63 ± 0.4 µg mL-1) in the cultivation fluid. The strain also showed the highest level of keratinase activity (39.10 ± 0.4 U mL-1). These data... |

| This study aimed at isolating and characterizing of microorganisms able to use linamarin as sole carbon source. Thirty one microbial strains were isolated from manipueira, a liquid effluent of cassava processing factories. Among these strains, Bacillus licheniformis (isolate 2_2) and Rhodotorulla glutinis (isolate L1) were able to degrade 71% and 95% of added linamarin, respectively, within 7 days, showing high biodegradation activity and great potential for detoxification of cassava processing wastewaters. |

| Abstract Adhirasam is a cereal based, doughnut shaped, deep fried dessert consumed in the southern regions of India. The dough used to prepare adhirasam is fermented and contains rice flour and jaggery. The aim of the present study was to characterize the cultivable bacteria associated with this fermented dough and to identify a suitable starter culture for the production of quality adhirasam. In total, one hundred and seventy bacterial isolates were recovered from de Man Rogosa Sharp (MRS) agar, nutrient agar, lysogeny agar and tryptic soy agar media. Out of the 170 bacterial isolates, sixteen isolates were selected based on their ability to tolerate glucose and sucrose. All the bacterial isolates tolerated 15% glucose and 30% sucrose. Analyses of 16S... |

| Endophytic bacteria associated with the fern Dicksonia sellowiana were investigated. The bacterial communities from the surface-sterilized pinnae and rachis segments of the plants from the Brazilian Atlantic Rainforest that grew in native field conditions were compared with the bacterial communities from plants grown in greenhouses and plants that were initially grown in greenhouses and then transferred to the forest. From 540 pinnae and 540 rachis segments, 163 (30.2%) and 346 (64.2%) were colonized by bacteria, respectively. The main bacterial genera and species that were isolated included Bacillus spp. (B. cereus, B. megaterium, B. pumilus and B. subtilis), Paenibacillus sp., Amphibacillus sp., Gracilibacillus sp., Micrococcus sp. and Stenotrophomonas... |

| This work presents some results on the use of microbes from the genus Bacillus for uptake of cadmium, zinc, copper and lead ions. Maximum copper bioaccumulations were 5.6 mol/g biomass for B. sphaericus, 5.9 mol/g biomass for B. cereus and B. subtilis, and 6.4 mol/g biomass for Bacillus sp. Maximum zinc bioaccumulations were 4.3 mol/g biomass for B. sphaericus, 4.6 mol/g biomass for B. cereus, 4.8 mol/g biomass for Bacillus sp. and 5.0 mol/g biomass for B. subtilis. Maximum cadmium bioaccumulations were 8.0 mol/g biomass for B. cereus, 9.5 mol/g biomass for B. subtilis, 10.8 mol/g biomass for Bacillus sp. and 11.8 mol/g biomass for B. sphaericus.

| Abstract A total of 48 endophytic bacteria were isolated from surface-sterilized tissues of the medicinal plant Lonicera japonica, which is grown in eastern China; six strains were selected for further study based on their potential ability to promote plant growth in vitro (siderophore and indoleacetic acid production). The bacteria were characterized by phylogenetically analyzing their 16S rRNA gene similarity, by examining their effect on the mycelial development of pathogenic fungi, by testing their potential plant growth-promoting characteristics, and by measuring wheat growth parameters after inoculation. Results showed that the number of endophytic bacteria in L. japonica varied among different tissues, but it remained relatively stable in the same... |

| A strictly aerobic, thermophilic, spore-forming bacteria was isolated from a soil sample collected in Campos dos Goytacazes City, Rio de Janeiro, Brazil. The cells of this organism were Gram-positive, catalase positive, actively motile, 1.2 µm wide and 5.3 µm long. Growth occurred at pH values ranging from 6.5 to 9.0, and optimum growth occurred at about pH 7.0. The optimum temperature for growth was around 55ºC, and the upper temperature limit for growth was around 70ºC. Yeast extract stimulated growth on glucose and was obligately required at supraoptimal temperatures (65ºC). The results of 16S rRNA sequence comparisons indicated that the isolate was closely related to Bacillus caldoxylolyticus and Bacillus sp strain AK1, and these three organisms... |
