A method for the quantitative determination of leucogenenol, a leucocytosis-inducing compound produced by Penicillium gilmanii, has been developed. The formation of leucogenenol in P. gilmanii and its diffusion into the culture fluid has been followed over a period of 12 weeks. The highest concentration of leucogenenol was found in the mycelium of rapidly growing cultures. The greatest concentr...
abstract: in order to determine genetic variability among 33 isolates of fusarium semitectum, morpho- logical and molecular studies were carried out. isolates from different paddy fields in the north of iran were separated from each other in four morphotype groups. the isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextro...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
The exact position of the actinomycetes or ray-fungi in the kingdom of lower forms of life has attracted considerable attention and has been a subject of much speculation. These organisms have been classified as bacteria, as fungi, and as a special group, either derived from one of the above or giving rise to both. With the accumulated knowledge concerning the morphology of the actinomycetes, i...
Sophorose (2-O-beta-glucopyranosyl-D-glucose) induces carboxymethyl cellulase in Trichoderma reesei QM6a mycelium with 1.5 to 2 h. The induction response to sophorose concentration, although complicated by the metabolism of sophorose, shows saturation kinetics. Most of the cellulase appears after most of the sophorose has been taken up, but the presence of an inducer is required to maintain cel...
DL-[1-14C]Mevalonic acid lactone (25ILc) was added in sterile water to a flask containing an 8-day culture of P. cyclopium. A second flask was similarly treated with DL[2-L4C]mevalonic acid lactone (10&c). After a further 3 days the flasks were harvested and the palitantin was extracted as before but in neither case did it show any significant activity. In addition the mycelium was Soxhlet-extr...
When Penicillium patulum was grown on Czapek-Dox agar, 6-methylsalicylic acid was produced as an aerial mycelium was forming. Nutrients were often plentiful in the medium when biosynthesis began. If the formation of an aerial mycelium was prevented by growing the fungus between two sheets of dialysis membrane, no 6-methylsalicylic acid was produced even when nutrients were completely consumed. ...
