| genetic component of growth rate and ovicidal activity in penicillium lanosum. | the growth rate and ovicidal activity of 10 complementary biauxotrophic mutants (haploid constitution) obtained from strain no 45 of the ovicidal fungus penicillium lanosum was studied. the quantitative characters were further evaluated in 17 diploid strains prepared from pairs of mutants. by means of correspondence analysis "linda" was determined the share of parent haploid strains in the variability of diploids. this share is interpreted as the estimate of the genetic component. in the case of ... | 1991 | 1837678 |

| citrinin toxicity in growing chicks. | male broiler chicks, from day-old to 3 weeks of age, were fed diets containing 0, 100, 220, 330, and 440 ppm citrinin produced by penicillium lanosum grown on whole corn. body weight decreased (p less than .05) when chicks were fed the diets containing 330 and 440 ppm citrinin. average body weight of chicks fed the diet containing 220 ppm citrinin was 8% less than that of chicks fed no toxin. feed utilization decreased (p less than .05) with chicks fed the diet containing 440 ppm citrinin. analy ... | 1981 | 7323000 |
| the effect of feeding corn molded with penicillium lanosum to broiler chicks. | penicillium lanosum was isolated from broiler feed obtained from troughs in a house in which the litter was wet and the chicks were substantially smaller than expected at the time of slaughter. corn was inoculated with the fungus, incubated for 8 weeks, dried, and incorporated in a broiler ration. the ration was fed to broiler chicks for a period of 2 weeks in order to evaluate toxicity. experimental chicks developed diarrhea and grew slower than the controls. gross lesions consisted of swollen ... | 1980 | 7375420 |

| diploids of ovicidal fungus penicillium lanosum. | by use of auxotrophic mutants of penicillium lanosum were prepared the heterokaryonts. from more rapidly growing sectors from heterokaryotic mycelium on minimal medium were isolated 17 diploid strains. they were prototrophic and on the whole they did not differ from the wild strain in their morphology and their growth rate. all diploids had considerably larger spores than the wild strain. ovicidity of one half of the diploids, as well as ovicidity of the wild strain was inconspicuous and low. ov ... | 1990 | 2150265 |
| differences in spontaneous mutation frequencies as a function of environmental stress in soil fungi at "evolution canyon," israel. | when various wild strains of penicillium lanosum and aspergillus niger were placed in the same mild laboratory environment, their frequencies of new spontaneous mutations were clearly related to whether they had been isolated from a region of high or low microclimatic stress. in the mild environment, the total frequencies of conidial color and morphological mutations in p. lanosum, summed over all relevant loci, ranged from 0.29% to 2.4% for six strains from the north-facing, less stressful "eur ... | 2008 | 18401030 |
| four psychrotolerant species with high chemical diversity consistently producing cycloaspeptide a, penicillium jamesonlandense sp. nov., penicillium ribium sp. nov., penicillium soppii and penicillium lanosum. | penicillium jamesonlandense is a novel species from greenland that grows exceptionally slowly at 25 degrees c and has an optimum temperature for growth of 17-18 degrees c. the novel species is more psychrotolerant than any other penicillium species described to date. isolates of this novel species produce a range of secondary metabolites with a high chemical diversity, represented by kojic acid, penicillic acid, griseofulvin, pseurotin, chrysogine, tryptoquivalins and cycloaspeptide. penicillium ... | 2006 | 16738124 |
| isolation and identification of citrinin produced by penicillium lanosum. | penicillium lanosum, when grown on corn, produces a metabolite which increases water intake and excretion by chicks. during a 5-hr test period, chicks fed inoculated corn as the only feed began excreting water within 2 hr and excreted as much as 36 ml, whereas chicks fed untreated corn did not excrete measurable amounts. chicks fed the inoculated corn drank more water than those fed untreated corn. the metabolite could not be extracted from oven-dried corn but was removed from air-dried corn whi ... | 1980 | 7433363 |
| haenamindole and fumiquinazoline analogs from a fungicolous isolate of penicillium lanosum. | three amino acid-derived compounds, haenamindole (1) and 2'-epi-fumiquinazolines c (2) and d (3), were isolated from cultures of a fungicolous isolate of penicillium lanosum (myc-1813=nrrl 66231). compound 1 was also encountered in cultures of p. corylophilum (myc-418=nrrl 28126). structure elucidation of these metabolites was based mainly on high resolution mass spectrometry and nmr data analysis. haenamindole (1) was found to be a recently reported diketopiperazine-type metabolite that incorpo ... | 2016 | 27328870 |
