Abstract
The present invention refers to a coating composition comprising a suspension of a microorganism, wherein the suspension comprises a pigmented vegetative cell, an unpigmented vegetative cell and a pigmented chlamydospore of the microorganism, and a surfactant ranging from 130 g/mol and 1500 g/mol. The invention further relates to a method for the preparation of the coating composition, a method for application coating one or more coating pre-layers and curing a material, a coated material obtainable by this method and a method for refreshing the coating of the coated material.
Claims14
A coating composition comprising a suspension of a fungus, wherein the suspension comprises 10-35% pigmented vegetative cells, 10-35% unpigmented vegetative cells, 50-70% pre-activated dormant chlamydospores of the fungus, and a biosurfactant produced by the fungus, wherein the biosurfactant is in an amount of 2 g/L to 10 g/L and has a molecular weight ranging from 130 g/mol to 1500 g/mol per repetitive unit, wherein the production of the biosurfactant is initiated by fatty acids and a dissolved oxygen content (DO2) in a range from 30% to 90%, wherein the fungus is Aureobasidium.
