The extracellular polysaccharides produced by sorne fungi involved in the deterioratlon of wood (Pleurotus species) and stone (Ulocladium atrum) were isolated and characterized. Both are 13-0 ..... 3)-linked glucans with considerable branching degree, as revealed by methylation analysis and 13C-NMR. The Pleurotus glucans present the most complex structure and the study was followed by the analy...

The effect of atrazine concentrations on mycelial growth and ligninolytic enzyme activities of eight native ligninolytic macrofungi isolated in Veracruz, México, were evaluated in a semi-solid culture medium. Inhibition of mycelial growth and growth rates were significantly affected (p=0.05) by atrazine concentrations (468, 937, 1875, and 3750 mg/l). In accordance with the median effective conc...

Pleurotus sajor caju spawns prepared, yield fruiting bodies, Aqueous extract of these was used to test for inhibitory against Tobacco Mosaic Virus. Infectivity assay (locallesion) method was employed for the anti-viral activity. Treatments, on host plants, were distributed using half-leaf method. The results indicated that extract of the edible mushroom showed anti-viral property.

Various bacteria were isolated from the casing layer soil of the culture bed of P. ostreatus and their role in fruiting body induction of the edible mushroom, P. ostreatus, was investigated. Analysis of the bacterial community isolated from the casing layer soil revealed that the composition of genera and number of cultivable bacteria were different for each sterilizing treatment. Bordetella wa...

Animals must move to find food and mates, and to avoid predators; movement thus influences survival and reproduction, and ultimately determines fitness. Precise description of movement and understanding of spatial and temporal patterns as well as relationships with intrinsic and extrinsic factors is important both for theoretical and applied reasons. We applied hidden semi-Markov models (HSMM) ...

BACKGROUND Clustering time-series data into discrete groups can improve prediction and provide insight into the nature of underlying, unobservable states of the system. However, temporal variation in probabilities of group occupancy, or the rates at which individuals move between groups, can obscure such signals. We use finite mixture and hidden Markov models (HMMs), two standard clustering tec...
