Cyanidation is the most commonly used process in the world for extracting silver from its ores. In recent years, mineral deposits with easily leachable silver are being depleted. On the other hand, there is an abundance of silver sulfosalts (thioarsenites and thioantimonites), which are difficult to dissolve with cyanide and...
Lactobacillus casei was entrapped in beads made with sodium alginate (A), amidated low-methoxyl pectin (P), and blends of A-P (1:2, 1:4, 1:6 ratios) by the extrusion technique. Diameter, sphericity and textural properties of the beads and the survivability of entrapped Lb. casei during yoghurt storage and in simulated gastrointestinal conditions...
Actualmente el interés en la producción de enzimas termoestables se ha incrementado debido a la diversidad de aplicaciones y beneficios industriales que representan. El objetivo de la presente investigación fue la caracterización de los factores bioquímicos responsables de la termoestabilidad de proteasas fúngicas producidas por Cultivo en Medio Sólido (CMS)....
Vibrio vulnificus is a halophylic bacterium widely distributed in coastal waters of seas, estuaries and other water bodies. Oysters, fish, sediments, water and plancton are reservoirs for V. Vulnificus, and it is thus important to assess the effect of salinity, temperature and seasonal changes on the viability of V. Vulnificus,...
Se analizan y describen los caracteres utilizados en la descripción de las especies del género Hydrolithon (Corallinales, Rhodophyta) lo que evidencia la diferencia e inconstancia de su uso a largo de las investigaciones que publican los registros para nuestro país desde 1960. Con la información obtenida se reevalúan estos caracteres...
We analyzed five representative species of marine catfish Ariidae family from both coasts of México (Pacific and Atlantic), through of the analysis, of the variability in 21 alloenzymatic loci to further the phylogeny of this group. Of the 21 loci resolved, 20 were polymorphic in Cathorops aguadulce (95.2%), 3 in...
