The crude fiber method gives an estimate of indigestible fiber in foods. It is determined by sequential extraction of a defatted sample with % H 2 SO 4 and % NaOH. The insoluble residue is collected by filtration, dried, weighed and ashed to correct for mineral contamination of the fiber.

Soil Sci. 69 Cited by:   A technique was described by Chinn () which is simple, effective and allows both quantitative and qualitative estimates to be made of the behaviour of fungi in soil.

A spore suspension is made with 10 ml of water plus detergent using a test-tube slant culture of the selected by: 8. Soil Science Society of America Book Series Books in the series are available from the Soil Science Society of America, South Segoe Road, Madison, WI USA.

I Soil Smear method: by using clean glass slides and press it in soil then stain these slides with lactophenol- Cotton Blue. I Indirect method I Dilution plate method: for quantitative studies but this method is not recommended for studying of fungi due to rapid and different types reproduction.

Effects of roots and of arbuscular-mycorrhizal (AM) fungi on the composition of soil bacterial colonies and the combined effects of AM fungus-rhizobacterium associations on plant and soil. SERIAL DILUTION METHOD Serial dilution method is one of the most old and usable method which is use for the isolation of fungi as well as for the isolation of viable bacterial colony.

3 Amjad Khan Afridi 29 /07/ In this method we collected our desire samples (soil, slag, water, milk, food) and make its dilution in the test tubes. This very simple concept is the basis for a large fraction of the industrial uses for soil microbiology such as isolating hydrocarbon-degrading bacteria, isolating bacteria that degrade various pollutants such as pesticides, PCBs, organochlorines, isolating bacteria (including actinomycetes) or fungi that produce new antibiotics, and many other.

Soil bacteria and fungi play pivotal roles in various biogeochemical cycles (BGC) Molin and Molin,Trevors, b, Wall and Virginia, and are responsible for the cycling of organic compounds. Soil microorganisms also influence above-ground ecosystems by contributing to plant nutrition George et al.,Timonen et al.,plant health Srivastava et al., Methods of Soil Analysis.

In this method, exactly 1 ml of each successive dilution is transferred into exactly 9 ml of liquid in a dilution blank, creating a 1.

Quantitative antifungal testing methods for textile fabrics under growth-supportive conditions were studied. Fungal growth activities on unfinished textile fabrics and textile fabrics modified. Method used for inoculating the solid media depends upon the purpose of inoculation- whether to have isolated colonies or to know the bacterial load of the sample (quantitative analysis).

For obtaining the isolated colonies streaking method is used, the most common method of inoculating an agar plate is streaking. Fig. Streaking method.

the entire community of fungi present in a soil sample. To facilitate the above studies modified methods were developed in the cultural technique. A weak agarsolution was used for all dilution work to assistin even distribution of soil particles. A simple rapid method was introduced for measuring out soil quadrats of known volume.

INTRODUCTION. A simple method of assaying soil phosphatase activity is described. It involves colorimetric estimation of the p -nitrophenol released by phosphatase activity when soil is incubated with buffered (pH 65) sodium p -nitrophenyl phosphate solution and toluene at 37° C for 1 hr.

A competitive PCR (cPCR) assay was developed to quantify the nematophagous fungus Verticillium chlamydosporium in soil. A γ-irradiated soil was seeded with different numbers of chlamydospores from V.

chlamydosporium isol and samples were obtained at time intervals of up to 8 weeks. Samples were analyzed by cPCR and by plating onto a semiselective medium. A fast and simple polymerase chain reaction method has been developed for detection of Phytophthora infestans oospores, the causal agent of Late blight of Potato in soil.

The method involves the disruption of oospores by grinding dry soil, using abrasive properties, in the presence of glass powder and skimmed milk powder within a short time.The great majority of the 80 + fungal species so far named and described are likely to occur in the soil environment at some stage in their life-cycle.

Fungi therefore have many different functions in soils, which include both active roles, such as the degradation of dead plant material, or inactive roles where propagules are present in the soil as resting states.•In quantitative research we collect numerical data. •This is closely connected to the final part of the definition: analysis using mathematically-based methods.

•In order to be able to use mathematically based methods our data have to be in numerical form. •This is not the case for qualitative research.
