Scanning electron micrographs of the nematode-egg-parasitic fungus Paecilomyces lilacinus infecting eggs of the root-knot nematode Meloidogyne spp. suggested the involvement of lytic enzymes. When grown on a liquid mineral salts medium, supplemented with different substrates as the sole N- and C-source, the fungus produced an extracellular protease. Colloidal chitin, vitellin and intact eggs of...

BACKGROUND Thorn injuries are common in the desert Southwest; however, the frequency and microbiology of thorn-associated infections have not been systematically described. Most information comes from case reports describing infections from atypical or environmental microorganisms. Our aim was to summarize the spectrum of thorn-associated infections. METHODS We conducted a retrospective revie...

bGalactosidase (commonly known as b-lactase; EC 3.2.1.23) is a multifunctional enzyme that can catalyze the hydrolysis of terminal non-reducing b-D-galactose residues in b-D-galactosides or transfer the galactosyl residue to saccharide acceptors to yield galactooligosaccharides (GOS). b-Galactosidase has a variety of applications in food and medical industries such as hydrolysis of lactose in m...

In recent decades, many fungal species have emerged as major causes of human disease. While invasive candidiasis, aspergillosis, and cryptococcosis remain very common, rates of infection by other opportunistic fungal pathogens such as Histoplasma capsulatum, Coccidioides immitis, Fusarium spp. and other yeasts and molds are on the rise. Adding to this bleak picture is the fact that treatment an...

Five lignans (secoisolariciresinol, pinoresinol, eudesmin, lariciresinol, and lariciresinol-4-methyl ether) were isolated from an MeOH extract from Araucaria araucana (Mol.) K. Koch wood for the first time in this species and their structures determined with spectroscopic methods. The antimicrobial activities of these compounds were determined for the bacteria Citrobacter sp., Bacillus subtilis...
