Ultrastructural study on the morphological changes in indigenous bacteria of mucous layer and chyme throughout the rat intestine.
Indigenous bacteria in the alimentary tract are exposed to various bactericidal peptides and digestive enzymes, but the viability status and morphological changes of indigenous bacteria are unclear. Therefore, the present study aimed to ultrastructurally clarify the degeneration and viability status of indigenous bacteria in the rat intestine. The majority of indigenous bacteria in the ileal mu...
متن کاملThe Origin and Composition of Pyrolusite Concretions in Hawaiian Soils!
THE SOILS of the drier regions of the Hawaiian Islands have a very high manganese content. Kelley ( 1909) has reported that certain darkcolored soils which are closely associated with the red soils have an Mna04 content ranging from 2.4 to .9.7 per cent.

15 صفحه اولCalcium carbonate concretions formed by the decomposition of organic matter.
Bacterial decomposition of butterfish and smelts in small sealed jars containing seawater and other solutions, for periods ranging from 65 to 205 days, results in a large increase in concentrations of dissolved bicarbonate, carbonate, and ammonia (plus volatile amines). Accompanying this is a rise in pH and the precipitation of Ca(++) ion from solution. The Ca(++) is not precipitated as CaCO(3)...
متن کاملBacterial diversity in the intestine of sea cucumber Stichopus japonicus
The intestinal bacterial diversity of Stichopus japonicus was investigated using 16S ribosomal RNA gene (rDNA) clone library and Polymerase Chain Reaction/Denaturing Gradient Gel Electrophoresis (PCR-DGGE). The clone library yielded a total of 188 clones, and these were sequenced and classified into 106 operational taxonomic units (OTUs) with sequence similarity ranging from 88 to 100%. The cov...
