1. Purificação parcial e caracterização das exopoligalacturonases II e III de Penicillium frequentans
Estudos prévios realizados em nosso laboratório demonstraram que o fungo Penicillium frequentans produz altos níveis de poligalacturonase e pectinesterase. Endopoligalacturonase I (Endo-PG I) e Exopoligalacturonase I (Exo-PG I) já foram previamente purificadas e caracterizadas. No presente trabalho foram separadas, purificadas parcialmente e caracterizad

2. Separation of Fungal Propagules by Partition in Aqueous Polymer Two-Phase Systems
Conidia of Penicillium chrysogenum and Penicillium frequentans and sporangiospores of Rhizopus rhizopodiformis, Rhizomucor pusillus, and Mucor racemosus were subjected to partition in aqueous polymer two-phase systems. The partition behavior differed drastically between the conidia of the two Penicillium species and the sporangiospores of the three species o

3. Selective partitioning of conidia of some Penicillium and Aspergillus species in aqueous two-phase systems.
Conidia of Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Penicillium brevi-compactum, Penicillium frequentans, Penicillium spinulosum, and Penicillium verrucosum var. cyclopium were subjected to partition at varying pH values in an aqueous two-phase system containing charged polyethylene glycol. In the system, the partition behavior of the co

4. 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

5. Respiratory disease in cork workers (`suberosis') 1
Pimentel, J. Cortez, and Avila, Ramiro (1973).Thorax, 28, 409-423. Respiratory disease in cork workers (`suberosis'). A clinical, immunological, and histological study of 63 workers in the cork industry with bronchopulmonary manifestations is described. From this study, it was possible to recognize three types of reaction to the inhalation of cork dust: asth
