The most important step is for the biocontrol agent to establish itself in the rhizosphere, in order to facilitate the interaction of the microrganism with the plant.
The microrganism during fermentation produces enzymes that degrade cellulose and lignin increasing by 40% the content of free phenolic compounds in relation to the original substrate (Schmidt & Badiale-Furlong, 2012; Oliveira et al.
Voriconazole, a recent azole antifungal acts by inhibiting the synthesis of ergosterol in the fungal membranes and ultimately the growth of the microrganism.
The origin of the microrganism that causes FIP--feline infectious peritonitis virus (FIPV)--can be traced to feline coronavirus (FCoV), a virus with a structure resembling the corona of the sun.

The system to which she refers in the text is bioMerieux's automated BacT/ALERT, based on the detection of carbon dioxide released by microrganism activity.
The effect of osmotic stress on the growth of microrganism was investigated in view of the osmotic pressure build up in fermentation systems designed to favour high volumetric ethanol productivity.
In 1981, an outbreak in Canada was first associated with the presence of this pathogen in foods, encouraging the development of research on the ubiquitous features of the microrganism and its pathogenicity (TODD & NOTERMANS, 2011).
When mycoplasmas were detected, UU was more frequently found in both groups, with a significant difference between cases and controls, with a higher incidence among the latter, indicating that UU is able to grow in healthy Fallopian tubes as a commensal microrganism.
