Effects of tropical fruit blends on fermentative and pigmentation aspects of probiotic native cultured goat milk.

Background: Fruits are sources of bioactive compounds such as phenolics that bring health benefits to consumers. The addition of fruit products and microorganisms with probiotic potential in fermented goat milk can facilitate the acquisition of these benefits through diet. In this sense, the objective of this study was to evaluate the effect of incorporating a mixture of ingredients from jaboticaba (), jambolana (), and mandacaru () fruits on fermentation parameters (pH, titratable acidity, viability of the native culture CNPC003 and the starter culture), associated with pigmentation (phenolic compound content and color) through experimental mixture design.

β-Glucosidase activity and antimicrobial properties of potentially probiotic autochthonous lactic cultures.

Background: The demand for lactic acid bacteria products, especially probiotics, has increased. Bacteria that increase polyphenol bioavailability and act as bio preservatives are sought after. This study aims to identify autochthonous lactic acid cultures from EMBRAPA that demonstrate β-glucosidase activity and inhibitory effect on microbial sanitary indicators.

MinC Oscillates from Pole to Pole to Ensure Proper Cell Division and Shape.

(Xac) is the causal agent of citrus canker, a disease that affects citrus crops and causes economic impact worldwide. To further characterize cell division in this plant pathogen, we investigated the role of the protein MinC in cell division, chromosome segregation, and peptidoglycan incorporation by deleting the gene using allele exchange. Xac with deleted exhibited the classic Δ phenotype observed in other bacteria deleted for components: minicells and short filamentation.

A protein expression system for tandem affinity purification in Xanthomonas citri subsp. citri.

Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp. citri (Xac), is one of the most devastating diseases to affect citrus crops. There is no treatment for citrus canker; effective control against the spread of Xac is usually achieved by the elimination of affected plants along with that of asymptomatic neighbors.
