| [production of patulin in a liquid medium by moulds belonging to the genera: aspergillus and penicillium (author's transl)]. | the toxinogenesis of 10 strains of penicillium granulatum, 5 of p. expansum, 4 of aspergillus terreus, 2 of a. clavatus, p. thomii, p. urticae, p. italicum and 1 of p. claviforme was tested at 26 degrees c in czapek's enriched liquid medium (8 p. 1000 glucose + 2 p. 1000 yeast extract). 6 strains of p. granulatum, 5 of p. expansum, 1 of p claviforme and p. thomii produced patulin after 9 days of culture. mycotoxin concentrations recovered was between 0.2 ppm and 3127 ppm. highly toxinogenic stra ... | 1977 | 596791 |
| patulin production by penicillium granulatum and inhibition of ruminal flora. | the maximum patulin production by penicillium granulatum was obtained during the 16th day of culture at 26 degrees c (2.9 g/l) on liquid czapek medium (+ 8 p. 1000 glucose), followed by 32 degrees c after 24 days and 20 degrees c after 32 days. at 26 degrees c patulin production was maximum before the greatest rate of sporulation when the ph of the medium was about 4. toxin production was studied by anaerobic culture for 75 days and then the cultures were exposed to ambient air. p. granulatum di ... | 1992 | 1573564 |
| [measuring of a double contamination by patulin and ochratoxin (author's transl)]. | the growth of byssochlamys nivea and p. granulatum was reduced by ochratoxin a (1 ppm, 10 ppm), whereas aspergillus ochraceus growth and toxinogenesis were not affected by 1 and 10 ppm of patulin. when penicillium granulatum and asperigillus ochraceus were placed in the same medium the former grew and produced its toxin and ochratoxin production by the latter was weakened. since patulin and ochratoxin can be found in the same substrate; the toxinogenic significance of in vitro strains is questio ... | 1980 | 7458236 |
| determination of the antimicrobial properties of oligo-2-hydroxy-1-naphthaldehyde. | oligo-2-hydroxy-1-naphthaldehyde (ohna) was synthesized by oxidative polycondensation using h2o2 (35%, aqueous solution), air o2 and naocl (34%, aqueous solution) by kaya and senol and the products were characterized by spectral techniques. antimicrobial activities of the first and second fractions of ohna were tested against corynobacterium xerosis ccm 2824, proteus vulgaris atcc 6897, staphylococcus epidermidis nrrl b-4877, s. aureus atcc 6538, enterobacter aerogenes atcc 13048, salmonella thy ... | 2005 | 16355978 |
| in vitro antioxidant potential of some soil fungi: screening of functional compounds and their purification from penicillium citrinum. | fungal isolates (aspergillus wentii 1, a. wentii 2, penicillium citrinum, penicillium granulatum) were selected to study their in vitro antioxidant potential by various assay procedures. czapek-dox's medium was selected for the growth of fungi as it supported the best antioxidant activity based on their ec(50) values, p. citrinum was the best followed by p. granulatum, a. wentii 1, and a. wentii 2. the chromatographic analyses showed several compounds possessing antioxidant activity in the funga ... | 2011 | 21603952 |
| experimental and theoretical investigations of the adhesion time of penicillium spores to cedar wood surface. | in this study, the adhesion of 4 penicillium strains (penicillium granulatum, penicillium crustosum, penicillium commune and penicillium chrysogenum) on cedar wood was examined qualitatively and quantitatively by using the extended dlvo (xdlvo) approach and the environmental scanning electronic microscopy (esem) technique. a comparison between the xdlvo theories and the esem technique was also investigated. the adhesion tests revealed that p. chrysogenum was not able to adhere on the cedar wood ... | 2012 | 23827572 |
| [toxinogenic moulds in silage. vii conservatives effects on patulin production (author's transl)]. | penicillium granulatum growth and patulin production were inhibited for a period of five months after propionic (0.5; 1; 2 p. 100) and formic acids (1.5; 3; 6 p. 1000) addition. propionic and formic acids as well as antracol (100, 400, 1000 ppm of propylene bis dithio carbamate zinc) and thibenzol (200, 600, 1200 ppm of thiabendazol) additions were not able to prevent patulin production by byssochlamys nivea. problems related to contamination of silages and corn by patulin was not completely sol ... | 1979 | 547833 |
| spirograterpene a, a tetracyclic spiro-diterpene with a fused 5/5/5/5 ring system from the deep-sea-derived fungus penicillium granulatum mccc 3a00475. | a novel spiro-tetracyclic diterpene, spirograterpene a (1), was isolated from the deep-sea-derived fungus penicillium granulatum mccc 3a00475, together with two biosynthetically related cyclopianes, conidiogenone i (2) and conidiogenone c (3). the relative configuration of 1 was elucidated by extensive spectroscopic analyses, and the absolute structure was established by the modified mosher's method. compound 1 is the second example of a diterpene featuring a 5/5/5/5 spirocyclic carbon skeleton. ... | 2017 | 28692272 |
