Most species are catalase-positive. Oxidase reaction varies between species. Voges–Proskauer reaction is negative. Nitrate reduction and casein, gelatin, and starch hydrolysis varies between species. Growth is inhibited by 5% NaCl. Optimum growth occurs at pH 7.0. Carbohydrates may be assimilated, ...

Many microorganisms produce VOCs with the ability to induce positive or negative changes in plant growth and seed germination. Negative changes associated with VOC production by various microorganisms, especially bacteria and fungi, include the following: reduction or inhibition of germination; stunting; ...

gene. Further processing steps such as cleavage of an N-terminal extension, head-to-tail circularization, and transport are encoded by further members of theacngene cluster (4490 bp). Amylocyclicin was found efficient against Gram-positive but not against Gram-negative bacteria (Scholz et al....
The plant extract itself showed strong inhibition on Bacillus cereus and none on the other Gram-positive and Gram-negative bacteria and fungi. The silver nanoparticles had antimicrobial activity against most of the tested microorganisms, with strong effect on B. cereus, while the gold nanoparticles ...

Strains grew optimally at 37 °C ± 2, pH 7.5 ± 1 and in the absence of NaCl concentrations. All strains had a positive catalase and a negative oxidase activity, except for BBCOL-015, which had a positive oxidase. The three strains metabolized arabinose, sucrose, melibiose, rha...
Biochemical analysis shows that it is positive for catalase, oxidase, hydrolysis of gelatin, starch, casein and negative for citrate, methyl red, Voges-Proskauer, nitrate, urea hydrolysis and oxidation/fermentation tests. Acid is produced from carbohydrates namely dextrose, fructose, maltose, mannose,...
2A). In general, four different expression profiles were found in which genes show positive (profiles 1 and 2) or negative (profiles 3 and 4) variations from 24 h to 48 h, and genes with expression levels that remain either stable (profiles 1 and 3) or altered (profiles 2 and 4...
