Usages:
For selective isolation and culture of Pseudomonas aeruginosa.
Principle:
Acetamidase bacteria can use acetamide as a carbon source and acetamide decomposition Alcaligenes; NaCl maintain osmotic balance; dipotassium phosphate and potassium dihydrogenphosphate as buffer; magnesium ions provide necessary growth ; agar medium as coagulant; phenol red as a pH indicator.

Acetamide 10g
NaCl 5g
Dipotassium hydrogen phosphate 1.39g
Potassium dihydrogen phosphate 0.73g
Magnesium sulfate 0.5g
Phenol red 0.012g
Agar 15g
Final pH 7.2 ± 0.2
Storage: Keep container tightly closed, store in a cool, dry place, away from bright light. Storage period of 3 years.

The Available Carbohydrates Assay Kit method is suitable for the determination of available carbohydrates (AVCHO) comprising *total digestible starch (TDS) plus maltodextrins, sucrose, D-glucose, D-fructose and lactose. New Improved method receiving ‘First Action’ status: AOAC 2020.07. This method is designed to simulate in vivo conditions in the human small intestine (i.e. a 4 h incubation time with PAA + AMG) in parallel with recent advances in Dietary Fiber (DF) methodology (K-RINTDF: AOAC Method 2017.16) and in accordance with the new (physiological based) definition of DF announced by Codex Alimentarius in 2009. Also, sucrose is hydrolysed with a specific “sucrase” enzyme which (unlike invertase which has been used traditionally for this reaction) has no action on fructo-oligosaccharides (FOS).
* Total digestible starch (TDS) is defined as starch that is digested in a 4 h period and is part of the carbohydrate that is available for digestion and absorption in the human small intestine.
