Background: Currently, microbial fermentation method has become the research hotspot for acetoin production. In our previous work, an acetoin-producing strain, Bacillus subtilis SF4-3, was isolated from Japanese traditional fermented food natto. However, its conversion of glucose to acetoin was relativel...
Legionella pneumophila es una bacteria ambiental capaz de sobrevivir en un amplio intervalo de condiciones físico-químicas y de colonizar los sistemas de distribución y almacenamiento del agua potable. Es el principal patógeno trasmitido por el agua que produce el 90% de los casos de legionelosis. El...
El objetivo del presente estudio fue optimizar la implementación de cultivos primarios a partir de muestras de
carcinoma renal de células claras (CRCC) para comprobar la conservación del fenotipo lipogénico contra cortes
fijados del mismo origen.
Se utilizaron muestras de pacientes con CRCC, evaluán...
Background To study the relationship between intracellular anabolism and astaxanthin production, the influence of intracellular protein and fatty acids on astaxanthin production by four mutant Phaffia rhodozyma strains and their variations was investigated in this research. Results First, the content of ...
We here report a clinical case of a female patient presenting with a three-month history of a white onychodystrophic lesion of both hallux. The infection was due to a mold, identified as Curvularia lunata var aeria. The Curvularia gender is related to the production of phaeohyphomycosis, Curvularia lunat...
Background CO2 emission, water pollution and petroleum shortage are the issues coming with the development of industry. A cost effective system was constructed to fix the CO2 in flue gas (15% CO2), remove nitrogen and phosphorus from manure wastewater and produce biofuels at the same time. The significan...

Background The properties of natural pigments, such as antioxidants, functional, medical, and nutraceutical, have demonstrated the advantages of these natural compounds over synthetic ones. Some products are accepted only when they are pigmented with natural, food-quality colorants: for example poultry p...

Background Optimization of nutrient feeding was developed to improve the growth of Bacillus subtilis in fed batch fermentation to increase the production of jiean-peptide (JAA). A central composite design (CCD) was used to obtain a model describing the relationship between glucose, total nitrogen, and th...
Background: Cyclodextrin glycosyltransferase (CGTase) from Amphibacillus sp. NPST-10 was successfully covalently immobilized on aminopropyl-functionalized silica coated superparamagnetic nanoparticles; and the properties of immobilized enzyme were investigated. The synthesis process included preparing of...
