| effect of cd⁺² on phosphate solubilizing abilities and hydrogen peroxide production of soil-borne micromycetes isolated from phragmites australis-rhizosphere. | the aims of this work were to evaluate the phosphate-solubilization and hydrogen peroxide (h2o2) production by the soil-borne micromycetes, aspergillus japonicus, penicillium italicum and penicillium dipodomyicola, isolated from phragmites australis rhizosphere and to study the effect of several concentrations of cadmium (cd(2+)) on both variables. our results showed that p. italicum achieved a higher p-solubilization and h2o2 production than a. japonicus and p. dipodomyicola, as only p. italicu ... | 2016 | 26646403 |
| fungal biodiversity and mycotoxigenic fungi in cooling-tower water systems in istanbul, turkey. | this is the first study to assess fungal diversity and mycotoxigenic fungi in open recirculating cooling-tower (ct) water systems (biofilm and water phase). the production capability of mycotoxin from fungal isolates was also examined. the mean fungal count in 21 different water and biofilm samples was determined as 234 cfu/100 ml and 4 cfu/cm(2). a total of 32 species were identified by internal transcribed spacer (its) sequencing. the most common isolated fungi belonged to the genera aspergill ... | 2017 | 28362312 |
| plant and fungal diversity in gut microbiota as revealed by molecular and culture investigations. | few studies describing eukaryotic communities in the human gut microbiota have been published. the objective of this study was to investigate comprehensively the repertoire of plant and fungal species in the gut microbiota of an obese patient. | 2013 | 23555039 |
| the sequence of the isoepoxydon dehydrogenase gene of the patulin biosynthetic pathway in penicillium species. | interest in species of the genus penicillium is related to their ability to produce the mycotoxin patulin and to cause spoilage of fruit products worldwide. the sequence of the isoepoxydon dehydrogenase (idh) gene, a gene in the patulin biosynthetic pathway, was determined for 28 strains representing 12 different penicillium species known to produce the mycotoxin patulin. isolates of penicillium carneum, penicillium clavigerum, penicillium concentricum, penicillium coprobium, penicillium dipodom ... | 2007 | 17043910 |
| species-specific identification of penicillium linked to patulin contamination. | certain species of penicillium have been reported to produce the mycotoxin patulin, and research was undertaken to identify these with the use of oligonucleotide primer pairs. species examined were found in food, plants, and soil and were reported to produce patulin. penicillium expansum is the most commonly detected species linked to the presence of patulin in apple juice. at least 10 different enzymes are involved in the patulin biosynthetic pathway, including the isoepoxydon dehydrogenase (id ... | 2007 | 18044450 |
| peniphenones a-d from the mangrove fungus penicillium dipodomyicola hn4-3a as inhibitors of mycobacterium tuberculosis phosphatase mptpb. | a pair of unusual benzannulated 6,6-spiroketal enantiomers [(-)-1 and (+)-1] and three new biogenetically related compounds (2-4), together with two known related analogues (5 and 6), have been isolated from a mangrove fungus, penicillium dipodomyicola hn4-3a. their structures were elucidated on the basis of spectroscopic analysis (1d and 2d nmr data) and x-ray crystallography. the absolute configurations of enantiomers (-)-1 and (+)-1 were determined using quantum chemical calculations of the e ... | 2014 | 24597756 |
