In the present study, a novel laccase from ascomycete Gliomastix murorum was produced in agro-industrial wastes and entrapped galactomannan beads for Reactive Blue 2 (Rb-2) decolorization. The maximum production agave bagasse-based medium occurred at 72 h (1798.6 UL−1). Entrapped decolorized ˃80% of 0.5 mM Rb-2 without addition redox mediator. Km substrate 1.42 mM, with Vmax 1.19 µmol min−1 lac...

Here we investigate the extent to which different Aspergillus species release galactomannan (GM) in vitro. Marked variability was observed in GM reactivity between and within Aspergillus species, with A. terreus strains showing the highest GM indexes. The in vivo significance of these findings remains to be determined.

The Bacova_02091 gene in the β-mannan utilization locus of Bacteroides ovatus encodes a family GH36 α-galactosidase (BoGal36A), transcriptionally upregulated during growth on galactomannan. Characterization of recombinant BoGal36A reveals unique properties compared to other GH36 α-galactosidases, which preferentially hydrolyse terminal α-galactose in raffinose family oligosaccharides. BoGal36A ...

We assessed the performance of galactomannan and (1→3)-β-d-glucan in 29 serum samples from patients with multiple myeloma and Waldenstrom's macroglobulinemia without invasive fungal disease to address issues of false positivity and uninterpretable results previously reported among patients with these conditions. Galactomannan and (1→3)-β-d-glucan assays were not falsely elevated in any patient....

Invasive aspergillosis (IA) is a severe infection with a 70% mortality rate. Aspergillus fumigatus is responsible for over 90% of those infections. The diagnosis of invasive aspergillosis is based on clinical sample culture and detection of fungal hyphae in histopathological examination. Additional tests may include the detection of the galactomannan antigen and of fungal genetic material in se...

The performance of antibody detection, antigen detection, and Aspergillus genus-specific PCR for diagnosing Aspergillus meningitis was investigated with 26 cerebrospinal fluid (CSF) samples obtained from a single patient with proven infection caused by Aspergillus fumigatus. Immunoglobulin G antibodies directed against Aspergillus were not detected by enzyme-linked immunosorbent assay in CSF or...

The effects of treating two biopolymers (Trigonella foenum—graceum galactomannan and xanthan gum mixtures) with microwaves ultrasound on the rheological aspects O/W emulsions were investigated. data obtained from steady shear flow fitted various models best chosen due to values R2 RMSE. oscillatory rheology demonstrated that not treated or had viscous-like behavior samples weak gel behavior. fo...
