A pellicle, a gel film of microbial cellulose, is a supermolecular system containing 99% of water by weight, which is closely related to an amorphous structure in it. Using ultra-small-angle neutron scattering, in order to cover over a wide range of length scales from nm to 10 microm, we examined the hierarchical amorphous structure in the microbial cellulose, which is synthesized by a bacteriu...

A relatively rapid and simple method for the determination of alpha, beta, and gamma cellulose is described. The method ordinarily employs a O.3-g sample, which need not be weighed accurately, but a O.03-g sample also gives fair results. Neither ash nor moisture determinations are involved, in fact, no precision weighings are made. The cellulose is oxidized by potassium dichromate solution, the...

Kidney beans, Phaseolus vulgaris, contain a proteinaceous inhibitor of alpha-amylase, which we have named phaseolamin. The inhibitor has been purified to homogeneity by conventional protein fractionation methods involving heat treatment, dialysis, and chromatography on DEAE-cellulose, Sephadex G-100, and CM-cellulose. Phaseolamin is specific for animal alpha-amylases, having no activity towards...

One of the major problems in environment is deforestation. In last five years, deforestation rate about 10 Million hectares per year. The main reason for dominance wood dependent industries. On other hand, agricultural biomass generated huge amounts India. Agricultural wastes are considered to be a promising and novel source preparation Cellulose, highly valued precursor production cellulose ba...

Crude and purified staphylococcal alpha-toxin were used to demonstrate that the platelet-damaging effect of crude alpha-toxin represents a fifth activity of the alpha-toxin molecule. The homogeneity of the purified toxin employed was demonstrated by ultracentrifugation, Ouchterlony, and immunoelectrophoretic methods. Continuous-flow electrophoretic migration studies demonstrated under a variety...

Background: Neonatal screening for abnormal hemoglobins provides a practical approach for the detection of sickling syndromes and other hemoglobin disorders such as a-thalassemia. Most screening programs utilize various electrophoretic techniques for the detection of abnormal hemoglobins Electrophoresis on cellulose acetate at pH 8.6 identifies increased amounts of Bart’s hemoglobin (Hb) associ...
