Abstract
The present invention relates to the in vitro use of a cationic hydroxyalkyl guar for maintaining or increasing the growth rate of microorganisms, wherein said cationic hydroxyalkyl guar has an average molecular weight of between 2,000 Daltons and 90,000 Daltons.
Claims18
A method, comprising contacting microorganisms with a cationic hydroxyalkyl guar in the presence of a culture medium in vitro or applying a biostimulant composition comprising microorganisms and the cationic hydroxyalkyl guar, to a plant, a seed or soil to increase growth of the microorganisms, wherein said cationic hydroxyalkyl guar has an average molecular weight of between 2,000 Daltons and 90,000 Daltons and said cationic hydroxyalkyl guar is present at a concentration to increase the growth rate of the microorganisms at least 5% compared to without the presence of the cationic hydroxyalkyl guar.
A biostimulant composition comprising at least one microorganism and at least one cationic hydroxyalkyl guar having an average molecular weight of between 2,000 Daltons and 90,000 Daltons, wherein said cationic hydroxyalkyl guar is present at a concentration to increase the growth rate of the microorganisms at least 5% compared to without the presence of the cationic hydroxyalkyl guar.
A kit comprising at least one microorganism and at least one cationic hydroxyalkyl guar having an average molecular weight of between 2,000 Daltons and 90,000 Daltons, wherein said cationic hydroxyalkyl guar is present at a concentration to increase the growth rate of the microorganisms at least 5% compared to without the presence of the cationic hydroxyalkyl guar.
