Some bacterial species can colonize humans and plants. It is almost impossible to prevent the contact of clinically pathogenic bacteria with food crops, and if they can persist there, they can reenter the human food chain and cause disease. On the leaf surface, microorganisms are exposed to a number of stress factors. It is unclear how they survive in such different environments. By increasing adhesion to diverse substrates, minimizing environmental differences, and providing protection against defence mechanisms, biofilms could provide part of the answer. Klebsiella pneumoniae subsp. pneumoniae is clinically important and also associated with fruit diseases, such as ?pineapple fruit collapse.? We aimed to characterize biofilm formation and adhesion mechanisms of this species isolated from pineapple in comparison with a clinical isolate. No differences were found between the two isolates quantitatively or qualitatively. Both tested positive for capsule formation and were hydrophobic, but neither produced adherence fibres, which might account for their relatively weak adhesion compared to the positive control Staphylococcus epidermidis ATCC 35984. Both produced biofilms on glass and polystyrene, more consistently at 40°C than 35°C, confirmed by atomic force and high-vacuum scanning electron microscopy. Biofilm formation was maintained in an acidic environment, which may be relevant phytopathologically. |

Coffee plantations present large spatial and temporal variability of yield, the variation along the years with high and low productions is known as bienniality. This study investigated the bienniality in different groups of genotypes of conilon coffee, classified by the ripening cycle, evaluating the crop yield of the clones along four years to determine the magnitude of the bienniality. The results indicate that, the bienniality is present in genotypes of conilon coffee from all the studied groups of genotypes, existing very biennial genotypes and also very stable genotypes within each group. |
