Feed supplied to pigs is considered an important vehicle for Salmonella enterica subsp. enterica introduction on farm. Salmonella can be able to form biofilm on several abiotic surfaces, which may contribute to environmental persistence. This study aimed to evaluate the biofilm formation capacity in Salmonella strains isolated from four Brazilian feed mills. The biofilm formation was assessed i...

Cellulose, the most abundant source of organic carbon on the planet, has wide-ranging industrial applications with increasing emphasis on biofuel production (1). Chemical methods to modify or degrade cellulose typically require strong acids and high temperatures. As such, enzymatic methods have become prominent in the bioconversion process. While the identification of active cellulases from bac...

Growth and the production of acetone, butanol, and ethanol by Clostridium beijerinckii NCIMB 8052 on several polysaccharides and sugars were analyzed. On crystalline cellulose, growth and solvent production were observed only when a mixture of fungal cellulases was added to the medium. On lichenan growth and solvent production occurred, but this polymer was only partially utilized. To increase ...

The aim of this study was to determine the effect of subinhibitory concentrations (sub-MICs) of ciprofloxacin, amikacin and colistin on biofilm formation, motility, curli fimbriae formation by planktonic and biofilm cells of E. coli strains isolated from the urine of patients with various urinary system infections. Quantification of biofilm formation was carried out using a microtiter plate ass...

Background: Milk is a reservoir for several groups of microorganisms, which may pose health risks. The aim of this work was to assess the antibiotic resistance and biofilm production in catalase-positive Gram-positive cocci isolated from Brazilian pasteurized milk. Methods: The bacteria were isolated using Baird-Parker agar and identified by Matrix-Assisted Laser Desorption/Ionization-Time-Of-...

Pasteurella multocida is a Gram-negative bacterium that causes haemorrhagic septicaemia in cattle and buffaloes. These organisms are involved the formation of biofilm can evade treatment. There no definitive study to screen genes associated with production multocida. The present describes real-time PCR based approach for screening formation. Out 10 isolates screened formation, five them produce...
