What is FTIR? Fourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties.

A conventional TVC is determined using an aerobic plate count method. The industry standard reference method for food products is the recently revised ISO 4833-1:2013 (Microbiology of the food chain – Horizontal method for the enumeration of microorganisms – Part 1: Colony-count at 30oC by the pour plate technique).

Thin-layer chromatography (TLC) is a very commonly used technique in synthetic chemistry for identifying compounds, determining their purity and following the progress of a reaction. It also permits the optimization of the solvent system for a given separation problem.

It is also called the aerobic colony count, standard plate count, Mesophilic count or Total Plate Count. ... It is not a measure of the entire bacterial population; it is a generic test for organisms that grow aerobically at mesophilic temperatures (25 to 40°C; 77 to 104°F). APC does not differentiate types of bacteria.

Thank you for your clear answer! It is my understanding that when using the GC content as a way to classify a bacteria into either the Firmicute or Actinobacteria phylum 60% is the cutoff. Above 60% is considered high GC and therefore Actinobacteria, and below 60% is considered low, and therefore Firmicute.

Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC) The FSC is a global certification system that enables specifiers to identify and purchase wood from well-managed forests. ... However, PEFC is not a standards agency but a mutual recognition scheme.

The SimPlate Total Plate Count (TPC) test, developed by IDEXX Laboratories, Inc., detects and quantitates total bacterial concentration in food after 24 h of incubation. ... It was concluded that SimPlate TPC is a suitable alternative for the detection and quantitation of foodborne bacteria.

RFSTDTC is the reference date/time that YOU choose according to YOUR method. This can e.g. be the date/time of informed consent, can (but must not be) the date of first study drug/treatment exposure. It could also e.g. be the date/time of screening.

Total leucocyte count (TLC) or white blood cell count measures the number of leucocytes in the body. The differential leucocyte count (DLC) measures the percentage of each type of WBC present in the blood. A differential count also can detect immature WBCs and abnormalities.

This is because the counting of CFU assumes that every colony is separate and founded by a single viable microbial cell. The plate count is linear for E. coli over the range of 30 to 300 CFU on a standard sized Petri dish.

For thousands of years, humans have used various physical methods of microbial control for food preservation. Common control methods include the application of high temperatures, radiation, filtration, and desiccation (drying), among others.

Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography is performed on a sheet of glass, plastic, or aluminium foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminium oxide (alumina), or cellulose.

Microbiology is a basic subject which is a sub section of biology. It deals with the life cycles and behaviour of microbes (bacteria/fungi etc.). Biotechnology is a wider subject and covers most of the microbiology in it.

Emtricitabine (FTC, Emtriva) and lamivudine (3TC, Epivir) belong to the nucleoside reverse transcriptase inhibitor (NRTI) class of antiretrovirals. They are a mainstay of first-line ART regimens and are considered equivalent and interchangeable in treatment guidelines.

TFA (trifluoroacetic acid) is a commonly used mobile phase additive for reversed-phase HPLC (RP-HPLC) separations of proteins and peptides. However, TFA interferes with and significantly reduces the LC/MS signal, lowering sensitivity.
