Beta-glucosidase is among the suite of enzymes produced
by white rot fungi (WRF) to biodegrade plant biomass. This study investigated
the enzymatic activities and kinetic properties of β-glucosidase from seventeen WRF comprised of the following
species from various geographical locations: Pleurotus ostreatus, Auricularia auricular, Polyporus
squamosus, Trametes versicolor, Lentinula edodes, and Grifola frondosa. All the WRF studied
showed β-glucosidase activities.
Significant variations in protein and carbohydrate contents were also recorded.
Beta-glucosidase activities after 30 min of incubation ranged from 6.4 μg (T. versicolor) to 225 μg (G. frondosa). The calculated kinetic
constant (Km) ranged from
0.47 μM (A. auricular-1120) to 719 μM (L.
Objective: The present study aimed at
investigating the correlations among coping, personality traits, and social
support for burn survivors. Method: Participants were 48 patients from a reference burn hospital who attended group
meetings at a non-governmental organization associated to that institution that
offers support to burn survivors. Data were collected from February to May,
2010. The participants answered a socio-demographic questionnaire and three
instruments: Coping Strategy Indicator (CSI), Personality Markers, and Social
Support Questionnaire (MOS Scale). Results: The data obtained showed a significant correlation among the
personality traits neuroticism and socialization and social support, as well as
between socialization and coping; however, differently than expected, no
significant correlation was established between social support and coping. Conclusion: Personality traits are
related to the perception of support from others; however the perception of
support does not influence the way burn survivors cope with their problems.
These data were discussed in order to broaden the knowledge and stimulate new
studies on the area, so that, based on this information, more efficient treatment
plans and interventions can be designed to fulfill both the physical and
emotional needs of these survivors with more competency and perceptiveness.
