A red-shifted, mutated form of the jellyfish green fluorescent protein (GFP) under control of a TEF promoter was expressed at high levels in the filamentous fungus Aureobasidium pullulans. In the three transformants studied, all morphotypes of the fungus. including pigmented chlamydospores, expressed GFP and fluoresced brightly. Confocal microscopy showed that the intracellular distribution of ...

In this study, cellulase, endoglucanase, and ?-glucosidase activity produced by three fungal strains (Aureobasidium pullulans, Neurospora crassa Trichoderma reesei) were determined on differently processed canola substrates [hexane extracted meal (HECM), washed HECM (WHECM), seed sprout (CSM)] in mono- co-culture fermentation under solid- submerged- state processes. Results showed that the inoc...

INTRODUCTION Aureobasidium pullulans is a saprophytic fungus that is widely distributed in the environment, and in the right host can be an opportunistic human pathogen. PRESENTATION OF CASE A 66-year-old man with Crohn's disease with a single kidney, and requiring total parenteral nutrition via a Hickman catheter, was admitted with a 10-week history of progressive shortness of breath, fevers...

Hortaea werneckii and Aureobasidium pullulans, black yeast-like fungi isolated from hypersaline waters of salterns as their natural ecological niche, have been previously defined as halophilic and halotolerant microorganisms, respectively. In the present study we assessed their growth and determined the intracellular cation concentrations of salt-adapted and non-salt-adapted cells of both speci...

Resident fruit microflora has been the source of biocontrol agents for the control of postharvest decay of fruits and the active ingredient in commercialized biocontrol products. With the exception of grapes and apples, information on the resident microflora of other fruits is only fragmentary, but greater knowledge in this area can be very helpful in developing biocontrol strategies. We charac...

In this work, an ad hoc method to identify and quantify polyphenols from caper berries was developed on high-performance liquid chromatography/electrospray ionisation source/mass spectrometry (HPLC-ESI-MS). The method was applied during fermentation carried out with Lactobacillus pentosus OM13 (Trial S) and without starter (Trial C). A total of five polyphenols were identified. All samples cont...

Aureobasidin A, a new antifungal antibiotic, was isolated from the culture medium of Aureobasidium pullulans R106. Aureobasidin A was a cyclic depsipeptide consisting of eight alpha-amino acid units and one hydroxy acid unit. The structures of the units were found by acid hydrolysis of the antibiotic to be 2(R)-hydroxy-3(R)-methylpentanoic acid, beta-hydroxy-N-methyl-L-valine, N-methyl-L-valine...
