| penicibilaenes a and b, sesquiterpenes with a tricyclo[6.3.1.0(1,5)]dodecane skeleton from the marine isolate of penicillium bilaiae ma-267. | penicibilaenes a (1) and b (2), two sesquiterpenes possessing a tricyclo[6.3.1.0(1,5)]dodecane skeleton, were characterized from penicillium bilaiae ma-267, a fungus obtained from the rhizospheric soil of the mangrove plant lumnitzera racemosa. the lack of some key cosy and noesy correlations made the structure elucidation of compound 1 difficult, which was solved by a x-ray crystallographic study. compounds 1 and 2 exhibited selective activity against the plant pathogenic fungus colletotrichum ... | 2014 | 25408229 |
| the effect of penicillium fungi on plant growth and phosphorus mobilization in neutral to alkaline soils from southern australia. | the phosphate solubilizing fungi penicillium radicum, penicillium bilaiae (strain rs7b-sd1), and an unidentified penicillium sp. designated strain kc6-w2 were tested for their ability to increase the growth and phosphorus (p) nutrition of wheat, medic, and lentil in three soils of neutral to alkaline ph reaction. the strongest plant growth promoting (pgp) strain was penicillium sp. kc6-w2, which stimulated significant increases in shoot growth and dry mass in seven of the nine experiments conduc ... | 2007 | 17496956 |
| penipratynolene, a novel nematicide from penicillium bilaiae chalabuda. | new acetylenic nematicidal compound, penipratynolene (1), methy (2'r)-4-(2'-hydroxy-3'-butynoxy)benzoate, together with two known compounds, 6-methoxycarbonylpicolinic acid (2) and 2,6-pyridinedicarboxylic acid (3), were isolated from the culture filtrate of penicillium bilaiae chalabuda. the structures of 1-3 were established by spectroscopic methods. the absolute configuration of 1 was confirmed by using a modified version of mosher's method. compounds 1-3 showed nematicidal activity of 77%, 5 ... | 2004 | 14745197 |
| the effect of application of micromycetes on plant growth, as well as soybean and barley yields. | the possibility of application of micromycetes (strains penicillium bilaiae pb14, aureobasidium pullulans ya05 and rhodotorula mucilaginosa yr07) to increase yields of soybean (glycine max cv almaty) and barley (hordeum vulgare cv arna) was estimated. it was shown that the most positive effect on germination energy and seed germination after seed treatment with liquid culture, supernatant and filtrate, is achieved at 1:5 dilution. in studying the influence of cell-associated and extracellular bi ... | 2015 | 26677462 |
| experimental determination of viability loss of penicillium bilaiae conidia during convective air-drying. | a study was conducted on the drying of penicillium bilaiae, a fungal micro-organism used to promote soil-bound phosphorous uptake in several crop species, such as wheat, canola and pulse crops. a wet pellet formed from a mixture of the inoculant and a starch-based carrier was air-dried to the appropriate water activity to extend the shelf-life of the viable fungal conidia. convective air-drying was examined as a low-energy alternative to the more expensive freeze-drying technology that is curren ... | 2005 | 15660217 |
| biodegradative potential of fungal isolates from sacral ambient: in vitro study as risk assessment implication for the conservation of wall paintings. | the principal purpose of the study was to evaluate in vitro the potential ability of fungal isolates obtained from the painted layer of frescoes and surrounding air to induce symptoms of fresco deterioration, associated with their growth and metabolism, so that the risk of such deterioration can be precisely assessed and appropriate conservation treatments formulated. biodegradative properties of the tested microfungi were qualitatively characterized through the use of a set of special agar plat ... | 2018 | 29309432 |
| maize yield response to a phosphorus-solubilizing microbial inoculant in field trials. | findings from multi-year, multi-site field trial experiments measuring maize yield response to inoculation with the phosphorus-solubilizing fungus,penicillium bilaiaechalabuda are presented. the main objective was to evaluate representative data on crop response to the inoculant across a broad set of different soil, agronomic management and climate conditions. a statistical analysis of crop yield response and its variability was conducted to guide further implementation of a stratified trial and ... | 2015 | 26500375 |
| enhanced solubilization of rock phosphate by penicillium bilaiae in ph-buffered solution culture. | little is known about how ph-buffering capacity affects phosphorus (p) solubilization by penicillium bilaiae. this study compared solubilization of rock phosphate (rp) by p. bilaiae in nonbuffered (ph 5.0) and buffered (ph 7.0) media. fungal growth reached the stationary phase around day 12 and was slightly enhanced in the buffered medium. the fungus reduced solution ph from 5.0 to 4.1 in the nonbuffered medium and from 7.0 to 4.9 in the buffered medium by day 12. phosphorus concentrations incre ... | 2006 | 17215904 |
