    Abstract Orange juice is consumed worldwide, with Brazil and the United States being the largest producers. The waste pulp corresponds to approximately 50% of the weight of the fruit. As a result, large amounts of solid wastes are generated by the citrus industry, making its disposal potentially hazardous to the environment. This work aimed at the modeling of orange waste drying in a conical spouted bed, for temperatures of 70, 80, and 90°C, and inlet flow rate 70% above minimum spouting velocity. A two-phase perfectly stirred tank reactor model was derived and used in a cascade configuration with time-varying parameter update.

    Abstract Bifidobacterium BB-12 was microencapsulated by spray drying using liquid whey or whey retentate obtained from nanofiltration and inulin or polydextrose. The microcapsules were then characterized and the viability of the bifidobacteria was determined for 90days at 4°C and at −20°C. All the microcapsules showed high count of bifidobacteria, low moisture content, and low water activity. The microcapsules showed similar morphologies and particle sizes. The density of the microcapsules decreased with the increase of the total solids of the feed solutions. The highest hygroscopicity was noted in the microcapsules produced with polydextrose. The time of dissolution in water was longer than it was in oil for all the samples. The presence of prebiotics in the microcapsules increased the L* values and decreased the b* values; meanwhile, the samples produced with whey retentate showed lower a* values. The results of the thermal analysis suggested that prebiotics improved the stability of the microcapsules.

    Abstract This study analyzed the RYP1 gene as a target for the molecular diagnosis of histoplasmosis. This assay detected fungal DNA in 13/13 blood samples from HIV/AIDS-patients with histoplasmosis. Therefore, the detection of RYP1 gene in whole blood sample is a quick and sensitive test to diagnose histoplasmosis.

    Abstract This work aimed at evaluating the antifungal susceptibility and production of virulence factors by Candida spp. isolated from sirenians in Brazil. The isolates (n = 105) were recovered from the natural cavities of Amazonian and West Indian manatees and were tested for the susceptibility to amphotericin B, itraconazole, and fluconazole and for the production of phospholipases, proteases, and biofilm. The minimum inhibitory concentrations (MICs) for amphotericin B ranged from 0.03 to 1 µg/mL, and no resistant isolates were detected. Itraconazole and fluconazole MICs ranged from 0.03 to 16 µg/mL and from 0.125 to 64 µg/mL, respectively, and 35.2% (37/105) of the isolates were resistant to at least one of these azole drugs. Concerning the production of virulence factors, phospholipase activity was observed in 67.6% (71/105) of the isolates, while protease activity and biofilm production were detected in 50.5% (53/105) and 32.4% (34/105) of the isolates, respectively. Since the natural cavities of manatees are colonized by resistant and virulent strains of Candida spp., these animals can act as sources of resistance and virulence genes for the environment, conspecifics and other animal species, demonstrating the potential environmental impacts associated with their release back into their natural habitat.
