What is physiological profiling?

What is physiological profiling?

Community-level physiological profiling (CLPP) is a technique which offers an easily applied protocol yielding information regarding mixed microbial community function and functional adaptations over space and time.

How the EcoPlate works to profile an environmental sample?

Analysis of environmental samples using BioLOG Ecoplates provides a “fingerprint” of carbon source usage by the microbes present in the sample. This community-level physiological profiling (CLPP) is considered an effective way to detect spatial and temporal changes in microbial communities.

How does an EcoPlate work?

Each EcoPlate is filled with a dilution of one soil suspension, thus representing one soil sample. The utilization rates of carbon compounds in the wells are quantified spectrophotometrically by following the reduction of water-soluble colourless triphenyl tetrazolium chloride to purple triphenyl formazan.

What is psychological profile?

A psychological profile is a tool that can help crime investigators by telling them the kind of perpetrator they are seeking. A psychological profile is built through evidence from the scene of the crime, which is integrated into psychological theory.

What is CLPP method?

Community-level physiological profiling (CLPP) based on sole carbon substrate utilization profiles (CSUP) is a rapid screening method used to characterize microbial communities of different habitats, ranging between sediments to seawater and between oligotrophic groundwater to soil and fertilizers.

What do Biolog plates measure?

GEN III MicroPlate Used for identification of more than 1,500 aerobic bacterial species. It contains 71 carbon source and 23 chemical sensitivity tests chosen to optimally differentiate aerobic bacteria. It can also be used to assess microbial community function.

What is Biolog EcoPlate?

The Biolog EcoPlate™ (Figure 1) was created specifically for community analysis and microbial ecological studies. In applied ecological research EcoPlates are used as both an assay of the stability of a normal population and to detect and assess changes following the onset of an environmental variable.

What is AWCD?

Acronym. Definition. AWCD. Average Well Colour Development (organic farming)

Why is it important to include a negative control well on the Biolog plate?

Why do you need to assay positive and negative control samples as well as your own experimental samples? Controls are needed to make sure the experiment worked. if there are no positive controls and the sample is negative, we can’t know if the sample was truly negative or if the assay process didn’t work.

Why is psychological profiling important?

The main psychological premise behind profiling is that there will be consistency between the way offenders act at the crime scene and who they are. Individual differentiation aims to establish differences between the behavioral actions of offenders and uses this to identify subgroups of crime scene types.

How is AWCD calculated?

For each soil sample and at each incubation time point, average well color development (AWCD) was calculated according to the equation:AWCD = [Σ (C – R)] / n where C represents the absorbance value of control wells (mean of 3 controls), R is the mean absorbance of the response wells (3 wells per carbon substrate), and …
