Abstract
The invention relates to the use of polyamines, tyramine and/or a plant extract containing same to stabilise microorganisms under an environmental stress, such as oxidative stress, osmotic stress or salt stress, heat stress, acid/base stress and/or stress linked to competitor microorganisms; and a composition comprising (a) polyamines, tyramine and/or a plant extract containing same, and (b) microorganisms.
Claims19
Method for stabilizing microorganisms under an environmental stress by contacting said microorganisms with an algae and/or plant extract, said extract containing polyamines and/or tyramine, wherein the algae and/or plant extract is an extract of brown algae of the Fucaceae family and/or an extract of beet molasses vinasse.
Composition comprising:
- (a) an algae and/or plant extract, said extract containing polyamines and/or tyramine, wherein the algae and/or plant extract is an extract of brown algae of the Fucaceae family and/or an extract of beet molasses vinasse, and
- (b) microorganisms chosen from:
- (i) atmospheric nitrogen fixing bacteria, (ii) plant growth promoting Rhizobacteria (PGPR), (iii) phosphorus-solubilising bacteria, (iv) root phytoprotectant bacteria (PGPR) capable of opposing the activity of pathogens, (v) phytohormone producing bacteria, (vi) bacteria involved in the process of mineralisation of organic matter, (vii) iron-solubilising bacteria, (viii) silica-solubilising bacteria, (ix) sulfur-oxidising bacteria, (x) lactic acid bacteria, (xi) bacteria of the genus Enterococcus spp., (xii) bacteria of the genus Pediococcus spp., (xiii) bacteria of the genus Bacillus licheniformis;
- (xiv) mycorrhizal fungi, (xv) yeasts of the genus Saccharomyces cerevisiae, and (xvi) a mixture of at least two microorganisms chosen from (i) to (xv).
