Various fractions were extracted from cell-wall material of Eupenicillium crustaceum, Penicillium brevi-compactum, P. decumbens, Aspergillus flavipes and A. ochraceus. The most characteristic fractions, which may have chemotaxonomic relevance, were F1I, an alpha-(1-3) glucan (alkalisoluble, water-insoluble), which amounted to 16.2-32.5% of the cell-wall… (More)
Penicillium frequentans secreted an exopolysaccharide composed mainly of N-acetyl-galactosamine (48.4%) and galactose, mannose and glucose in the ratio 4:1:1, that were alpha - (1----4) and alpha - (1----3) linked predominantly. Greater polysaccharide production was achieved in old cultures grown statically with glucose as carbon source.
—Recent studies show that autistic children tend to speak and interact more in the presence of an interactive robot. Unfortunately, most of the robotic experiments were conducted in highly controlled clinical settings or limited selected home environments due to the high deployment cost. In this paper, we design a low-cost interactive robot that can be… (More)
