Jostaberry Jostaberry The jostaberry ("Ribes" × "nidigrolaria") is a complex-cross fruit bush in the genus "Ribes", involving three original species, the black currant "R. nigrum", the North American coastal black gooseberry "R. divaricatum", and the European gooseberry "R. uva-crispa". It is similar to "Ribes × culverwellii", the Jochelbeere, which is descended from just two of these species, "R. nigrum" and "R. uva-crispa". The cultivated plants are tetraploid. They are descended from two separate first-generation crosses, both of which produced very few fruit. Fertile tetraploids were produced using colchicine. The name "Jostaberry" was created via combining the German words for blackcurrant and
Epicoccum nigrum (a of 0.99 to 0.97), growth is optimized at water vapour saturation. "Epicoccum nigrum" produces a variety of biomedically and industrially useful metabolites, including important antifungal agents and pigments, including: flavipin, epicorazines A and B, epirodin, epicocconone, and a variety of carotenoid pigments. "Epicoccum nigrum" has also been utilized in the biosynthetic manufacture of silver- and gold nanoparticles. A highly robust and ubiquitous fungus, "E. nigrum" has an almost global spread, occurring in the Americas, Asia, and Europe. Spores of "E. nigrum" have been cultured from a variety of environments, predominantly soil (i.e. peat, forest floor, raw humus, compost, tundra,
