CBT-L01  – Total Viable Count

Detection of aerobic or microaerophilic mesophilic microorganisms which are able to grow on complete media.

CO-L02 – Coliforms

Rod-shaped aerobic, Gram-negative, non spore-forming, cytochrome oxidase negative microorganism; fermenting lactose with production of acids in the presence of bile salts or other surfactants.

EC-L22 – Escherichia coli

Rod-shaped aerobic, Gram-negative, non spore-forming, cytochrome oxidase negative microorganism; fermenting lactose with production of acids in the presence of bile salts or other surfactants; at a temperature of 44 °C produce indole from tryptophan.

EB-L03 – Enterobacteriaceae 

Gram-negative microorganisms, aerobic-anaerobic facultative, non spore-forming, oxidase negative, ferment glucose and lactose with gas production, reduce nitrate and are negative for oxidase test.

SP-L04 – Staphylococcus aureus 

Gram-positive cocci, coagulase positive, catalase positive, fixed, non spore-forming, facultative anaerobes, fermenting mannitol and osmotolerant.

PAO-L05 – Pseudomonas aeruginosa 

Moveable non spore-forming microorganism, rod-shaped, Gram-negative aerobic-anaerobic facultative, cytochrome oxidase and catalase positive; produce pyocyanine.

EF-L09 – Enterococcus spp.

Gram-positive, fixed, facultative anaerobes, non hemolytic, catalase negative microorganism; fermenting glucose without gas production and hydrolyze esculin.

LY-L07 – Listeria spp.

Gram-positive, non spore-forming, facultative anaerobic microorganisms, resistant to many antibiotics. Grow at pH between 5 and 9 and in the presence of NaCl to 10%. Catalase positive, oxidase negative, do not hydrolyze urea, gelatin and casein. Do not reduce nitrates and do not produce indole nor hydrogen sulfide.

SL-L06 – Salmonella spp. 

Gram-negative, aerobic-anaerobic facultative enterobacteria, able to ferment mannitol. Catalase positive, produce hydrogen sulfide, reduce nitrate to nitrite.

SC-L11 – Yeast 

Unicellular eukaryotic, heterotrophic, highly aerobic organisms, growing in carbon-rich substrates, resistant to high concentrations of antibiotics and sulphonamides.
