Peritonitis is a common problem in patients undergoing peritoneal dialysis. However, peritonitis due to Cunninghamella (C.) bertholletiae, a fungus of the class Zygomycetes, is rare. We present a case of fungal peritonitis in a patient on continuous ambulatory peritoneal dialysis due to kidney rejection. Direct examination of the patient's peritoneal fluid showed fungal hyphae, and the culture ...

The Quercus mongolica has a high utilization value in industrial economic sector. species is distributed throughout Korea, however, the damage caused by deterioration such as discoloration and decay severe. For this reason, of Q. an obstacle to its use wood, but research on factors insufficient. In study, we focused fungi factor influencing mongolica, isolated identified from deteriorated mongo...

Two filamentous fungi, Cunninghamella bainieri ATCC 9244 and Aspergillus niger BCRC 32720, were used to investigate the biotransformation of isosteviol lactone (4alpha-carboxy-13alpha-hydroxy-13,16- seco-ent-19-norbeyeran-16-oic acid 13,16-lactone) ( 2), which was derived by reacting isosteviol ( ent-16-oxobeyeran-19-oic acid) ( 1) with m-chloroperbenzoic acid. Incubation of 2 with C. bainieri ...

Microbial transformation of imbricatolic acid (1) by Aspergillus niger afforded 1alpha-hydroxyimbricatolic acid (2), while transformation with Rhizopus nigricans yielded 15-hydroxy-8,17-epoxylabdan-19-oic acid (3). When the diterpene 1 was added to a Cunninghamella echinulata culture, the main products were the microbial metabolites mycophenolic acid (4) and its 3-hydroxy derivative 5. All the ...

Quinoline, which belongs to N-heterocyclic compounds, occurs naturally in the environment and is used in numerous industrial processes. The structures of various chemicals, such as dyes and medicines, are based on this compound. Due to that fact, quinoline and its derivatives are widely distributed in environment and can exert toxic effects on organisms from different trophic levels. The abilit...

Studies were carried out with Cunninghamella elegans UCP/WFCC 0542 to evaluate the effects of an abundant supply of amino acids, asparagine and corn steep liquor associated with sucrose on the production of biomass and chitosan by submerged fermentation. The concentrations of the components of the culture medium which were determined by a 2³ full factorial design evaluated the interactions and ...
