Estimation of the microbial biomass in tidal flat sediment by fumigation-extraction

Radiotracer Estimation of Microbial Biomass in Lake Sediment

The biomass of sediment organisms can be measured by a.llowing carbon tracer to distribute itself through sediment cores. Application of this method to sediment from Marion lake, British Columbia, indicated that most of the sediment microorganisms were concentrated in the top 2 cm of sediment, where the total biomass of microorganisms was estimated to be 183IJ.g C/cm2• The radiotracer estimate ...

Measurement of microbial biomass N:C by chloroform fumigation-incubation

Harris, D., Voroney, R. P. and Paul, E. A. 1997. Measurement of microbial biomass N:C by chloroform fumigation-incubation. Can. J. Soil Sci. 77: 507–514. We present a calculation for soil microbial biomass N:C ratio determined from a 10-d incubation following chloroform fumigation. The calculation is based on a mathematical model of the N content of the preand post-fumigation soil microbial bio...

study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...

Loktanella sediminilitoris sp. nov., isolated from tidal flat sediment.

A Gram-stain-negative, non-motile, rod-shaped bacterial strain, designated D1-W3(T), was isolated from tidal flat sediment of the South Sea, South Korea, and subjected to a taxonomic study using a polyphasic approach. Strain D1-W3(T) grew optimally at pH 7.0-8.0, at 25 °C and in the presence of 2 % (w/v) NaCl. Neighbour-joining phylogenetic analyses based on 16S rRNA gene sequences revealed tha...
