specific Embodiment approach A
[0091] A method for fermentation of Chryseobasidiomycetes, comprising the following steps:
[0092] a) providing a medium having a dry matter content of 0.1 to 0.3% by weight and containing less than 0.1% by weight of an organic nitrogen source;
[0093] b) Use at least one fungal inoculation medium belonging to the black yeast species, the inoculation density is 0.01g CDW / L to 50g CDW / L;
[0094] c) adding at least one carbon source in a concentration of 1 to 20% by weight;
[0095] d) mixing the culture medium according to step d) and at least one fungus for a period of 24 to 400 hours;
[0096] e) removing 30 to 90% by weight of said culture medium and said at least one fungus;
[0097] f) adding 30 to 90% by weight of a medium additionally containing a carbon source as defined in step a);
[0098] g) repeat steps c) to f) 2 to 100 times;
[0099] wherein at least one of steps c) to g) is carried out at a relative gas content of 0.005 to 0.5;
[0100] h) optionally f...

[0105] a) providing a medium having a dry matter content of 0.1 to 0.3% by weight and containing less than 0.1% by weight of an organic nitrogen source;
[0106] b) Use at least one fungal inoculation medium belonging to the black yeast species, the inoculation density is 0.01g CDW / L to 50g CDW / L;
[0107] c) adding sucrose at a concentration of 1 to 20% by weight;
[0108] d) mixing the culture medium according to step d) and at least one fungus for a period of 24 to 400 hours;
[0109] e) removing 30 to 90% by weight of said culture medium and said at least one fungus;
[0110] f) adding 30 to 90% by weight of a medium additionally containing a carbon source as defined in step a);
[0111] g) repeat steps c) to f) 2 to 100 times;
[0112] wherein at least one of steps c) to g) is carried out at a relative gas content of 0.005 to 0.2,
[0113] h) optionally filtering the cult...

[0117] A method for fermentation of Chryseobasidiomycetes, comprising the following steps:
[0118] a) providing a medium having a dry matter content of 0.1 to 0.3% by weight and containing less than 0.1% by weight of an organic nitrogen source;
[0119] b) Use at least one fungal inoculation medium belonging to the black yeast species, the inoculation density is 0.01g CDW / L to 50g CDW / L;
[0120] c) adding sucrose at a concentration of 1 to 20% by weight;
[0121] d) mixing the culture medium according to step d) and at least one fungus for a period of 24 to 400 hours;
[0122] e) removing 30 to 90% by weight of the culture medium and at least one fungus;
[0123] f) adding 30 to 90% by weight of a medium additionally containing a carbon source as defined in step a);
[0124] g) repeat steps c) to f) 2 to 100 times;
[0125] wherein at least one of steps c) to g) is carried out at a relative gas content of 0.005 to 0.2 and at a temperature of 24 to 30° C. and at a pH ...
