A new antibiotic, leucinostatin, derived from Penicillium lilacinum.
A new antibiotic, leucinostatin, was isolated from the culture filtrate of Fenicillium lilacinum. The antibiotic was obtained in the form of white prisms, decomposing at 131~136°C, and showing optical rotation [^]d2+644° (c 0.5, methanol). The ultraviolet absorption spectrum showed only an inflection at 220nm in methanol. The antibiotic gave a positive reaction to biuret and negative to ninhydr...
متن کاملXanthoepocin, a new antibiotic from Penicillium simplicissimum IFO5762.
A new antifungal antibiotic xanthoepocin was isolated from the culture broth of Penicillium simplicissimum IFO5762. Xanthoepocin was obtained from the culture fluid by solvent extraction and chromatographic purification. It showed antibiotic activity against Gram-positive bacteria and yeasts.
متن کاملEffect of LED Blue Light on Penicillium digitatum and Penicillium italicum Strains.
Studies on the antimicrobial properties of light have considerably increased due in part to the development of resistance to actual control methods. This study investigates the potential of light-emitting diodes (LED) blue light for controlling Penicillium digitatum and Penicillium italicum. These fungi are the most devastating postharvest pathogens of citrus fruit and cause important losses du...

متن کاملRavynic acid, an antibiotic polyeneyne tetramic acid from Penicillium sp. elucidated through synthesis.
A new antibiotic natural product, ravynic acid, has been isolated from a Penicillium sp. of fungus, collected from Ravensbourne National Park. The 3-acylpolyenyne tetramic acid structure was definitively elucidated via synthesis. Highlights of the synthetic method include the heat induced formation of the 3-acylphosphorane tetramic acid and a selective Wittig cross-coupling to efficiently prepa...
