In the starch hydrolysis test, the test bacteria are grown on agar plates containing starch. If the bacteria have the ability to hydrolyze starch, it does so in the medium, particularly in the areas surrounding their growth while the rest of the area of the plate still contain non-hydrolysed...
In the starch hydrolysis test, the test bacteria are grown on agar plates containing starch. After colonies of the bacteria are visible, the plates are flooded with iodine solution. If the bacteria have the ability to hydrolyse starch, its colonies hydrolyse the starch ...
The Agar Disc Diffusion Assay and Liquid Culture Test measure the distributions of inhibitory effect towards type of bacterial contamination in terms of Gram-positive, Gram-negative and their combination of wider spectrum activity in the blend films. For the first time, the inhibition size ...
In addition, the antimicrobial properties of the polymer films against Gram-positive bacteria compared to Gram-negative bacteria were enhanced by the addition of nanoparticles to the films and the viability of fibroblast cells was increased. In general, among the films prepared, the PVA/ST/CS/NiO...
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...
B. subtilis is a Gram-positive bacterium, that has been widely used as a cell factory for the production of various industrial enzymes due to its generally regarded as safe (GRAS) nature, excellent secretory capability, low nutritional demands, and well-established fermentation processes. Although ...
A distinction is made between anionic surfactants consisting of a hydrophobic radical and a negatively charged hydrophilic head group, amphoteric surfactants which carry both a negative and a compensating positive charge, cationic surfactants which in addition to a hydrophobic radical have a positively ...
(yellow inc). The colour of the connecting line reflects either the positive correlation (red) or negative correlation (blue) between bile acids and phenotypes or between bile acids and microbes. The width of connecting line reflects the strength of the statistical linear association (model ...
According to the literature, alkylation or quaternization of tertiary amines with alkyl halides has a positive effect on nanoclay’s thermomechanical properties [56], and thus more efficient exfoliation/intercalation. 3.2.2. Tensile Strength Parametric analysis data for the tensile strength showed that...
