Starch Hydrolysis test a. Media: Starch Agarb. Exoenzyme: AmylaseC. Reagent: Iodine will turn dark blue/ black color in presence of starchD. Positive results= no blue/black around bacteria means the bacteria did produce amylaseNegative results = blue/black around bacteria means the bacteria did...
Conventional analysis of the recovered salt showed that the anion was a phosphate (strong positive test with molybdate, tests negative for carbonate, chloride, sulfate). The cations as determined by atomic absorption spectroscopy were essentially: K+, Na+, with minor amounts of Ca2+ and Mg2+. ...
Streptococcus iniae is one of the few Gram positive streptococcal species capable of hydrolyzing starch. The starch hydrolysis test is essential for its identification. The biochemical reaction for starch in multi-test systems (API 20 Strep and API CH 50) is starch acidification, not starch ...
Halo (clearing) around the streak = no casein present, positive for casein protease production Opaque white up to/under streak = casein present, negative for casein protease production Spirit Blue Agar Plate Inoculation method: surface streak with loop ...
The test was performed at 10 °C, and the experimental data were adjusted to the power law. 2.7.3. Microbiological count Streptococcus thermophilus and Lactobacillus bulgaricus were counted using specific growth agar. MRS (Merk) agar for Lactobacillus growth and M17 (Merk) agar for Streptococcus ...
The antibacterial activities of the bio-adhesive samples were tested using the agar diffusion method on Gram-negative Escherichia coli (E. coli, ATCC25922) and Gram- positive Staphylococcus aureus (S. aureus, ATCC25923) bacteria. The bacteria were cultured in brain heart fusion broth at 37 °C...
