Purification and characterization of an endo-beta-D-xylanase from major soldier salivary glands of the termite Macrotermes subhyalinus with dual activity against carboxymethylcellulose
An enzyme with apparent dual functions as a xylanase and carboxymethylcellulase was purified from the major soldier salivary glands of the termite Macrotermes subhyalinus. The preparation was found homogeneous by gel electrophoresis after successive chromatography on anion-exchange, cation-exchange and hydro- phobic interaction columns. The specific activities towards carboxymethylcellulose and...

Chromosome study in few species of Acridids (Acrididae: Tryxalinae): Karyotypic analysis and distribution patterns of constitutive heterochromatin
Chromosomes with detailed karyotypic information (nature, number, size, relative length, length of X-chromosome, nature of X-chromosome) and C-banding patterns of few species of grasshoppers belonging to sub-familiy Tryxalinae are discussed. The karyotypes comprises of acrocentric chromosomes with complement number 2n = 23 (male). Constitutive heterochromatin distribution was found at centomeric,...

Managing nematode pests and improving yield of pineapple with Mucuna pruriens in Ghana
We investigated the potentials of a non-traditional legume crop, Mucuna pruriensand fallow treatments in managing plant parasitic nematodes population and improving the yield of pineapple in 2008 to 2009 at Asamankese in the Eastern region of Ghana. Nematode population density/200 cm3 soil at 6 months of application of treatments and at harvest, population/g-1 of pineapple root and yield of...
