13. Repression of endo-1,4-beta-glucanase formation in Penicillium janthinellum and product inhibition of its 1,4-beta-glucanases and cellobiases.
Endo-1,4-beta-glucanase formation of Penicillium janthinellum was repressed by glucose, sophorose, and glycerol. Chromatography on DEAE-Sephadex A-50 was employed to separate the 1,4-beta-glucanases from two cellobiases. The 1,4-beta-glucanases were inhibited competitively by cellobiose and glucose, and the two cellobiases were inhibited by glucose and gluco

14. Production and Some Properties of a New Type of Acid Carboxypeptidase of Penicillium Molds
Among some 38 strains of the genus Penicillium we investigated seven wild-type strains (P. daleae IFO-6087, P. frequentans AHU-8328, P. funiculosum IAM-7013, P. janthinellum IFO-8070, IAM-7026, P. lividum IAM-7200, and P. oxalicum AHU-8336) that were found to be excellent strains for a new type of acid carboxypeptidase production in a surface koji culture at

15. Formation and Location of 1,4-β-Glucanases and 1,4-β-Glucosidases from Penicillium janthinellum
Formation and location of 1,4-β-glucanases and 1,4-β-glucosidases were studied in cultures of Penicillium janthinellum grown on Avicel, sodium carboxymethyl cellulose, cellobiose, glucose, mannose, and maltose. Endo-1,4-β-glucanases were found to be cell free, and their formation was induced by cellobiose. 1,4-β-Glucosidases, on the other hand, were form

16. Submerged Production, Purification, and Crystallization of Acid Carboxypeptidase from Penicillium janthinellum IFO-8070
Penicillium janthinellum IFO-8070 produced an acid carboxypeptidase of molecular weight 51,000 in a liquid medium at 25 C. Maximum enzyme concentration was obtained within 3 to 6 days in a medium containing 2% wheat bran, 1% defatted soybean, and 1% KH2PO4; the initial pH was 2 to 4. When submerged aerobic conditions were used, a 51,000-molecular-weight acid

17. Autoradiographic method to screen for soil microorganisms which accumulate zinc.
An autoradiographic method was developed to screen for and isolate soil microorganisms which accumulate zinc (Zn). Diluted soil samples (Rubicon fine sand, Entic Haplorthods [pH 5.9]) were plated on soil extract-glucose agar containing radioactive 65Zn. After 7 days of incubation, individual colonies which accumulated sufficient 65Zn could be detected by aut

18. Distribution and properties of fructosyl amino acid oxidase in fungi.
Fructosyl amino acid oxidase, and enzyme that can be used for the determination of glycated proteins in blood samples from diabetic patients, was used to screen cultures in our microorganism culture collection. Fructosyl amino acid oxidase was found only in the strains of four genera of fungi, Aspergillus, Fusarium, Gibberella, and Penicillium and exhibited

19. Degradation and Mineralization of High-Molecular-Weight Polycyclic Aromatic Hydrocarbons by Defined Fungal-Bacterial Cocultures
This study investigated the biodegradation of high-molecular-weight polycyclic aromatic hydrocarbons (PAHs) in liquid media and soil by bacteria (Stenotrophomonas maltophilia VUN 10,010 and bacterial consortium VUN 10,009) and a fungus (Penicillium janthinellum VUO 10,201) that were isolated from separate creosote- and manufactured-gas plant-contaminated soi

20. EFFECT OF SALINITY AND TEMPERATURE ON COCCIDIOIDES IMMITIS AND THREE ANTAGONISTIC SOIL SAPROPHYTES
Egeberg, Roger O. (University of Southern California, Los Angeles), Ann F. Elconin, and Margaret C. Egeberg. Effect of salinity and temperature on Coccidioides immitis and three antagonistic soil saprophytes. J. Bacteriol. 88:473–476. 1964.—Experiments exploring the factors which determine the ability of Coccidioides immitis to survive and reproduce in t
