An application of geraniol in preparation of formulation for promoting synthesis of Pseudomonas aeruginosa 3OC.sub.12-HSL signal molecules is provided. It was found that geraniol slightly inhibits growth of Pseudomonas aeruginosa PAO1 strain, but can significantly promote synthesis of the 3OC.sub.12-HSL signal molecules of the bacterium, and thus can be applied to preparation of formulation for promoting synthesis of the Pseudomonas aeruginosa 3OC.sub.12-HSL signal molecules.

Provided is a lactic acid bacteria growth promoter which has a growth promotion effect on lactic acid bacteria. The lactic acid bacteria growth promoter includes at least one peptide selected from the group consisting of: a first peptide having a total number of residues of not more than 9 and comprising a hydrophobic amino acid residue at the C-terminus; and a second peptide having a total number of residues of not more than 9. The ratio of the total number of hydrophobic amino acid residues and proline residues to the total number of residues is not less than 2/3.

A novel microstructure of a mycelium material exhibiting a high mass density whereby the mycelium material exhibits a much greater spatial density of hyphal branches and hyphal connections than is otherwise found in nature. The material further provides improved macroscopic properties typified by high tensile strength, high flexural toughness and increased tear strength.

The present invention relates to a method for improving lactic acid bacteria in survival rate, storage stability, resistance to acid or bile, and adherence to intestinal epithelial cells by coating the surface of lactic acid bacteria with silk fibroin, and a lactic acid bacteria composition prepared therethrough. Conventional techniques construct only a physical protective barrier outside a lactic acid bacteria body by multi-stage coating and thus retain the limitation of being unable to identify an effect on the coherence of lactic acid bacteria to intestinal epithelial cells upon the uptake of the lactic acid bacteria. In contrast, the present invention provides a method in which lactic acid bacteria is coated with silk fibroin extracted from cocoons, whereby the lactic acid bacteria is improved in stability under a storage and distribution condition as well as having remarkably increased stability and intestinal adherence particularly under an intestinal environment.

A method of promoting fungal spore germination. The method includes the step of contacting a fungal spore with a germination-promoting concentration of an exogenous imizoquin.
