BACKGROUND Colorants derived from natural sources look set to overtake synthetic colorants in market value as manufacturers continue to meet the rising demand for clean label ingredients - particularly in food applications. Many ascomycetous fungi naturally synthesize and secrete pigments and thus provide readily available additional and/or alternative sources of natural colorants that are inde...

La contaminación por metales pesados es actualmente uno de los problemas ambientales más serios y complejos tratar. Las pilas lixiviación las industrias mineras se caracterizan su elevado contenido en disueltos, además ser considerado un hábitat propicio para el desarrollo microorganismos resistentes. Entre ellos, aquellos autóctonos con adaptaciones fisiológicas que le permiten tolerar elevada...

Cellulolytic enzymes are synthesized by a large number of micro-organisms which include fungi, actinomycetes, gliding bacteria (myxobacteria) and true bacteria. However, only the fungi appear to excrete large amounts of cellulase enzymes in active form into culture media and not surprisingly these are the enzyme systems that have been most extensively studied. Bacterial cellulases are cell-wall...

The surface mycobiota of three types of Slovenian dry-cured meat products were isolated from a total of 75 items of product that were sampled periodically during the drying/ripening stage of processing. The predominant filamentous fungal genus isolated was Penicillium. Eurotium spp., Aspergillus versicolor and Cladosporium spp. were isolated from only two of the products. Eight Penicillium spec...

Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study aimed to identify the secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...
