For example, by utilizing acetic acid, the yeast can raise the pH of pickles sufficiently to allow the growth of less acid-tolerant bacteria. [5] Besides, as with other yeasts, the concentration of fermentable sugar in a product affects the rate of spoilage by Z. bailii , e.g. the yeast grows faster in the presence of 10% (w/w) than 1% (w/w ...
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]
Plant disease triangle. Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [10] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease. [11]
The plant disease triangle represents the factors necessary for disease to occur. Plant disease forecasting is a management system used to predict the occurrence or change in severity of plant diseases. At the field scale, these systems are used by growers to make economic decisions about disease treatments for control.
Almost all Ustilaginales species share a dimorphic life cycle that includes an asexual, saprophitic yeast-like stage and a filamentous sexual stage that is required to parasitize a host. [6] The parasitic phase involves karyogamy , the process of fusing two haploid nuclei (present in haploid teliospore cells), followed by meiosis . [ 6 ]
The use of potatoes, water from potato boiling, eggs, or sugar in a bread dough accelerates the growth of yeast. Most yeasts used in baking are of the same species common in alcoholic fermentation. In addition, Saccharomyces exiguus (also known as S. minor), a wild yeast found on plants, fruits, and grains, is occasionally used for baking. In ...
Zygomycosis is the broadest term to refer to infections caused by bread mold fungi of the zygomycota phylum. However, because zygomycota has been identified as polyphyletic, and is not included in modern fungal classification systems, the diseases that zygomycosis can refer to are better called by their specific names: mucormycosis [1] (after Mucorales), phycomycosis [2] (after Phycomycetes ...
To protect tree nuts and corn plants affected by A. flavus, scientists of the Agricultural Research Service found that treating these plants with the yeast Pichia anomala reduced the growth of A. flavus. The study showed that treating pistachio trees with P. anomala inhibited the growth of A. flavus up to 97% when compared to untreated trees. [16]
