intergenic complementation of glucoamylase and citric acid production in two species of aspergillus.all auxotrophs of aspergillus foetidus and all but two auxotrophs of a. niger which we isolated yield glucoamylase and citric acid, respectively, at levels below that of the prototrophic strain from which they were derived. results of representative heterokaryon tests suggest that the nucleus was principally responsible for the inheritance of citric acid or glucoamylase production. most somatic diploid strains of a. foetidus gave rise to higher yields of glucoamylase when compared to their haplo ...19734716723

production of a new type of acid carboxypeptidase of molds of the aspergillus niger group.the ability of 88 fungi, which had been obtained as high-potency strains for acid proteinase production, to produce a new type of acid carboxypeptidase (having on optimal ph of about 3 for hydrolysis of benzyloxycarbonyl-glutamyltyrosine) in surface koji culture was determined. among the aspergilli, substantial amounts of this new acid carboxypeptidase were produced by aspergillus saitoi, a. usamii, a. awamori, a. inuii, and a. niger. maximum yields of acid carboxypeptidase per gram of substrate ...19734796163

the pectic enzymes of aspergillus niger. a second exopolygalacturonase.1. a second exopolygalacturonase was separated from a mycelial extract of aspergillus niger with a 265-fold purification and a recovery of 1%. 2. unlike the first exopolygalacturonase this enzyme showed no requirement for metal activators, nor was it inhibited by chelating agents. 3. the two exopolygalacturonases were also distinguished by their ph optima and stability. 4. the enzyme progressively removed the terminal galacturonic residues from alpha-(1-->4)-linked galacturonide chains, converti ...19664960793

effect of maltose on glucoamylase formation by aspergillus niger.low levels of glucoamylase are produced when aspergillus niger is grown on sorbitol, but substitution of the latter by glucose, maltose, or starch results in greater formation of glucoamylase as measured by enzymatic activity. both glucoamylase i and glucoamylase ii are formed in a yeast extract medium; however, glucoamylase i appears to be the only form produced when ammonium chloride is the nitrogen source. maltose or isomaltose (1.4 x 10(-4)m), but no other disaccharides or monosaccharides, d ...19725053881

polyprenols of aspergillus niger. their characterization, biosynthesis and subcellular distribution.a polyprenol complex of aspergillus niger was shown, by using spectrometric methods, to consist of a family of exo-methylene-hexahydroprenols that contain between 18 and 24 isoprene residues per molecule. each prenol contains two trans residues, three saturated residues (alpha, omega and psi) and an exo-methylene substituent on the carbon atom beta to the isopropyl group in each omega-residue. the ubiquinone complex consisted of 90% ubiquinone-9, 9% ubiquinone-8 and 1% ubiquinone-10. the amount ...19725073731
polyprenol phosphate as an acceptor of mannose from guanosine diphosphate mannose in aspergillus niger.growth of aspergillus niger in the presence of [2-(14)c]mevalonate and (32)p(i) led to the formation of a lipid, containing (14)c (0.14% of dose) and (32)p (0.009% of dose), that had chromatographic properties identical with those of exo-methylene-hexahydropolyprenol phosphate. when a particulate enzyme preparation from the thallus of a. niger was incubated with gdp-[(14)c]mannose, the main radioactive products were mannose 1-phosphate (57% of products) and mannose (18%). in addition radioactive ...19725073732

fungi isolated from flue-cured tobacco inoculated in the field with storage fungi.flue-cured tobacco inoculated in the field with a. amstelodami, a. flavus, a. ochraceus, a. repens, a. ruber, and a species of penicillium was rarely invaded by these fungi. regardless of inoculum, the predominant fungi reisolated from green tissue were species of alternaria and cladosporium. after curing, a. repens, a. niger, and species of alternaria and a species of penicillium were the most commonly isolated fungi. the fungus used as inoculum was not the predominant fungus reisolated from gr ...19715102779

production and properties of galactosidases from corticium rolfsii.when corticum rolfsii was grown in a medium containing bran extract under aerobic conditions, it secreted alpha-d-galactosidase and beta-d-galactosidase into the culture fluid. pectin also stimulated the production of these enzymes, whereas galactose, glucose, and sucrose stimulated their production to a lesser degree. c. rolfsii produced greater amounts of both enzymes than aspergillus niger. both galactosidases in the culture medium hydrolyzed alpha- and beta-p-nitrophenyl-d-galactosides as we ...19695370656

fatty acid toxicity and methyl ketone production in aspergillus niger.vegetative hyphae of aspergillus niger rapidly converted caproic acid into 2-pentanone. more caproic acid was required for maximal ketone production at alkaline as compared to acidic ph values. further increases in caproate concentrations at each ph value tested (4.5, 5.5, 6.5, 7.5, and 8.5) resulted in inhibition of ketone production and o(2) uptake. at alkaline ph values (8.5 and 7.5), oxygen uptake above the endogenous level and the production of 2-pentanone were parallel. this relationship d ...19705411757
chemical morphology of glucan and chitin in the cell wall of the yeast phase of paracoccidioides brasiliensis.short and thick fibers were observed on the outer surface of the yeast phase of paracoccidioides brasiliensis, and long and thin fibers were seen on the inner surface. the long fibers disappear with chitinase treatment and are composed of chitin. the short fibers disappear under alkali treatment and are composed of alpha-glucan. comparisons with alpha-(1 --> 3)-glucan isolated from aspergillus niger and polyporus betulinus and with chitin from fungal origin support our point of view.19705413832

effects of n2-o2 and co2-o2 tensions on growth of fungi isolated from damaged flue-cured tobacco.ten fungi, aspergillus niger, a. flavus, a. ochraceus, a. ruber, a. repens, a. amstelodami, alternaria tenuis, penicillium brevi-compactum, cladosporium herbarum, and chaetomium dolicotrichum, were isolated from moldy flue-cured tobacco and grown in various mixtures of n(2)-o(2) or co(2)-o(2). a 1 to 5% concentration of o(2) in an n(2) atmosphere caused the greatest change in growth of the nine species, and a 10 to 20% concentration of o(2) for a. flavus. all species, except a. amstelodami and a ...19705461786
