fermentation test

fermentation test

An obsolete term for a crude test that distinguishes glucose from other reducing sugars by virtue of the fact that glucose can serve as a substrate for yeast fermentation, while other reducing sugars (e.g., lactose, galactose) do not.

The results of Tamekuni's first cold fermentation test used an Acaia variety prepared with pulped natural processing, followed by 72 hours of fermentation in a cold room at temperatures of 11-13 degrees Celsius in GrainPro bags.
In the analysis of fermentation test, performed on saccharin substrates using Saccharomyces cerevisiae FT-858, the yeast presented ability to metabolize these carbon sources in different Brix concentrations, since there was evidence of fermentation by the presence of foam and bubbles in the Duhran tubes (Table 2).
Biochemical analyses including pH, temperature, lactose fermentation test (LAC), indole test (IND), methyl red test (MR), Voges-Proskauer test (VP), urease test (URE), catalase test (CAT), aerobic and anaerobic test (Ae/An) were measured.
Culture on blood agar showed abundant growth of golden-yellow colonies of staphylococcus(Figure 3).Gram stain, positive catalase test and mannitol fermentation test confirmed it to beStaphylococcus aureus.Other tests like Ziehl-Neelsen stain, KOH mount and fungal cultures were negative.Biopsy was done which wasconsistent with the findings of botryomycosis.
cutaneum were presumptively identified to the species level by using germ tube test, high temperature (45[degrees]C) tolerance test, carbohydrate fermentation test, urease test and by microscopic examination of chlamydospore, pseudohyphae, budding yeasts and arthroconidia production on Rice Extract Agar (REA) medium.
