13. The shelf life of standardized sugarcane juice stored under refrigeration
Abstract The shelf life (SL) of freshly extracted sugarcane juice is limited to a few hours, and the use of hurdle technology is a strategy to ensure its safety and stability. The SL of standardized cane juice (19.4 °Brix, 0.085% acidity and pH 4.35), pasteurized at 95 °C/30 s and stored under refrigeration, was estimated. Ideal (4 °C), commercial (8 °C)

14. Thermotolerance of Histoplasma capsulatum at 40 °C predominates among clinical isolates from different Latin American regions
ABSTRACT The yeast phase of 22 Histoplasma capsulatum clinical isolates from Mexico, Argentina, Colombia, and Guatemala and three reference strains, one from Panama and two from the United States of America (USA), were screened for thermosensitivity characteristics using different analyses. Growth curves at 0, 3, 6, 12, 24, and 30 h of incubation at 37 and 4

15. Organic acids and hydrogen peroxide can replace chlorinated compounds as sanitizers on strawberries, cucumbers and rocket leaves
Abstract This work evaluated the effectiveness of 1 and 2% acetic and lactic acid, 3% hydrogen peroxide, 200 mg/L sodium hypochlorite and 200 mg/L sodium dichloroisocyanurate to reducing natural contaminants as well as Salmonella enterica Enteritidis inoculated on the surface of strawberries, cucumbers, and rocket leaves. The reduction of aerobic mesophilic

16. Comparative analysis of enzymatic activity of tannase in non-conventional yeasts to produce ellagic acid
Abstract Non-conventional yeasts represent an alternative for microorganisms that are capable to produce the enzyme Tannase (EC 3.1.1.20), which has many applications is the food and pharmaceutical industry as it stands out for its ability to produce ellagic acid out of the enzymatic hydrolysis of ellagitannins. Ellagic acid has been studied in the medical a

18. Isolation of Malassezia spp. in HIV-positive patients with and without seborrheic dermatitis
Abstract Background Malassezia, a skin saprophyte, is frequently isolated from patients with seborrheic dermatitis, which is one of the most common dermatoses in HIV-infected patients. Its role in pathophysiology has not been defined. Objective To determine whether patients living with HIV and seborrheic dermatitis have more Malassezia than those without s

19. Dominant yeasts associated to mango (Mangifera indica) and rose apple (Syzygium malaccense) fruit pulps investigated by culture-based methods
Abstract: The biotechnological potential of yeasts associated to different habitats in Colombia has been poorly studied, especially the yeasts associated with different plant structures. Fruit pulps are interesting substrates mainly for the growth of yeast species, that can positively affect the productivity and quality of some bioeconomic species. Therefore

21. Synthesis, characterization and antimicrobial activity of Cr (III), Co (II) and Ni (II) complexes with 2-thiazoline-2-tiol derivative ligands against bacteria and yeasts of clinical importance
Abstract: Four novel Cr (III), Co (II) and Ni (II) complexes with 2-thiazoline-2-tiol derivative ligands were synthesized and characterized using elemental, physiochemical, and spectroscopy analytical methods. The results showed the formation of ligands coordinated by sulfur atoms of the C = S bond to the L1 ligand and by the sulfur atom of the C-S bond and/
