The microcrystalline cellulose is an important ingredient in pharmaceutical, food, cosmetic and other industries. In this study, the microcrystalline cellulose, obtained from the stalk of Sorghum caudatum was evaluated for its physical and tableting characteristics with a view to assessing its usefulness in pharmaceutical tableting. The microcrystalline cellulose, obtained from the stalk of Sor...

Macronuclear DNA content in Paramecium caudatum was found to be almost unchanged with a mean of about 400C during the earlier two-thirds of the life span in terms of the number of fissions and then it dropped rapidly to about one-fifth of the initial content. The age when rapid DNA decline occurred corresponded to that when the characteristics of senescence appeared. This decreasing pattern of ...

Competition among invertebrates was studied in mixed culture (the ciliates Paramecium caudatum and Paramecium bursaria and the rotifer Brachionis plicatilis) under laboratory conditions. The invertebrates were fed on various food sources: 1) Chlorella biomass and 2) biomasses of bacteria and yeast. The P.bursaria – Chlorella condutrix endosymbiosis was used a natural model of a simple biotic cy...

It is technically difficult to acquire large-field images under the complexity and cost restrictions of a diagnostic and instant field research purpose. The goal of the introduced large-field imaging system is to achieve a tolerable resolution for detecting microscale particles or objects in the entire image field without the field-curvature effect, while maintaining a cost-effective procedure ...

Azo dyes in textile industry effluent are one of the major toxic contaminants causing a severe threat to life. Bioremediation is most cost-effective and environmentally beneficial innovative biotechnologically technique used mitigate dyes’ effects aquatic environments. The purpose present study was determine azo degradation potential ciliate, Paramecium caudatum, isolated from industrial wastew...

Whether live bacteria are required to culture the rumen protozoa Entodinium exiguum and E. caudatum in vitro was studied. Treatments were protozoa plus antibiotics (PA), PA plus autoclaved bacteria (PAB) or protozoa plus live bacteria (PLB). Generation times at 24 h were 22.8 and 31.0 h for E. exiguum and E. caudatum. Protozoal concentrations were unaffected by the absence of bacteria up to 48 ...

The toxicity of 14 commercial natural dyes which are widely used as food additives in Japan was studied on Paramecium caudatum. Laccaic acid and capsanthin were found to be very toxic to Paramecium caudatum. Some of the commercially available carminic acid and crocin were also toxic. The inhibitory effect of natural food dyes on leucine aminopeptidase, acid phosphatase and esterase in vitro was...

In this study, we revealed that the lectin wheat germ agglutinin (WGA) and its specific binding sugars, N-acetylneuraminic acid (NeuAc) and Nacetylglucosamine (GlcNAc), inhibited mating pair formation in Paramecium caudatum. The concentrations that caused 50% inhibition (IC50) were 17 nM, 3 mM and 30 mM, respectively. Using FITCWGA, it was shown fluorescence-cytochemically that WGA bound to the...
