This test method is a presumptive quantification of clostridium spp. in fermentation samples found within the ethanol production process.

This test method is a colorimetric test used to determine Chemical Oxygen Demand (COD) in water and wastewater samples. COD measures the amount of oxygen required to chemically oxidize organic and inorganic matter in a sample, indicating the pollution or organic load. This method uses a dichromate digestion followed by spectrophotometric measurement.
This test method measures an oil’s resistance to crystallization, serving as an indicator of winterization efficiency and stearin removal. It is applicable to normal, refined, and dry animal and vegetable oils.
This test method describes the enzyme-substrate-based detection of total coliforms and Escherichia coli in drinking water, surface water, and wastewater using the Colilert® test. This method is based on defined substrate technology, where specific enzymes produced by coliforms and E. coli react with added substrates to produce color and fluorescence, allowing for easy detection after… Continue reading Coliform / E.coli [P/A (24 hr)]
This test method uses a calculation involving total, saturated, and unsatured fatty acids to quantify triglycerides in oils and fats.
The FDA’s Bacteriological Analytical Manual (BAM) method for Bacillus cereus outlines procedures for the detection and enumeration of this spore-forming, foodborne pathogen in foods, ingredients, and environmental samples. B. cereus is known to cause diarrheal and emetic (vomiting) illnesses and is commonly associated with starchy or protein-rich foods such as rice, dairy, and meat products.
This test method is a semi-quantitative test used to detect and characterize specific groups of bacteria in water, soil, and biofilm samples. It is commonly used to identify the presence and activity of bacteria such as iron-related bacteria (IRB), sulfate-reducing bacteria (SRB), slime-forming bacteria, and others involved in biofouling, corrosion, or water quality issues.
This test method isolates individual bacterial colonies from a mixed culture using aseptic technique, enabling the growth of pure cultures for identification, characterization, or further testing.
This test method is a standardized procedure for determining 5-day Biochemical Oxygen Demand (BOD₅) in water and wastewater. BOD measures the amount of dissolved oxygen (DO) consumed by microorganisms while breaking down organic matter under aerobic conditions over a 5-day period at 20 °C. It is widely used to assess the organic pollution load and treatment… Continue reading BOD
This test method is a standardized procedure for determining 5-day Biochemical Oxygen Demand (BOD₅) in water and wastewater. BOD (Soluble) first filters particulate matter from the sample, then measures the amount of dissolved oxygen (DO) consumed by microorganisms while breaking down organic matter under aerobic conditions over a 5-day period at 20 °C. It is widely… Continue reading BOD [Soluble]
