Bacteria in Plant Growth Promotion and Protection

Original language description

The replacement of chemical fertilizers and pesticides and the transition to sustainable plant agriculture requires a deeper understanding of interspecies relationships in nature, including those between plants and microorganisms. Many plant-populating bacteria, called epi- and endophytes, can promote plant growth as well as prevent the development of plant diseases or prevent plant pests. The bacteria can thus be used in organic microbial pesticides, fungicides and fertilizers. Useful properties of bacteria in this sense are the production of enzymes such as chitinases, the formation of secondary metabolites inhibiting fungal growth, the ability to produce plant hormones, the solubilization of phosphates, the release of ammonium ions and others. The advantage of using bacteria is also their ability to grow on agricultural and food waste substrates such as brewery mash, whey, waste from animal production (feathers, meat separation residues, fish scales, etc.).These wastes, after relatively easy pretreatment by hydrolysis under mild conditions (no pressure, low acid or base concentration), can be used as a complex culture medium for bacteria. The composition of the culture medium and the setting of culture conditions can influence not only the growth of bacteria but also the production of desired metabolites and enzymes. After cultivation, the whole medium together with the bacteria can be used for application to plants. The concept of this bacterial utilization and at the same time waste valorization within circular economy will be demonstrated with the example of the endophytic bacterium Pantoea agglomerans DBM 3797, isolated from hops.
