2. Mycological contamination in dental unit waterlines in Istanbul, Turkey
Studies on dental units (DUs) are conducted either for the prevention or the reduction of the density of bacterial contamination in dental unit waterlines (DUWLs). However, the existence of fungi in the these systems requires more attention. During dental treatment, direct contact with water contaminated with fungi such as Candida, Aspergillus, or inhalation

3. Imobilização de lipases produzidas por fermentação em estado sólido utilizando Penicillium verrucosum em suportes hidrofóbicos
O principal interesse em imobilizar uma enzima é obter um biocatalisador com atividade e estabilidade que não sejam afetadas durante o processo, em comparação à sua forma livre. Aliado ao potencial biotecnológico que as lipases apresentam, a aplicação destas em nível industrial requer a investigação de técnicas viáveis para reutilização e aume

4. Evaluation of enzymatic potential of filamentous fungi isolated from different sources / AvaliaÃÃo do potencial enzimÃtico de fungos filamentosos isolados de diferentes fontes
Enzymes are protein macromolecules responsible for the acceleration of the chemical reactions that maintain and regulate living organisms. They occur in nature and can be from vegetable, animal and microbial sources. Due to high industrial demand the microbial sources are the most used. The filamentous fungi compose the group of microorganisms with highest n

5. Produção e caracterização parcial de lipase obtida por fermentação submersa de Penicillium verrucosum utilizando meio convencional e industrial
O grande interesse atual na produção de lipases está relacionado às potenciais aplicações biotecnológicas que estas enzimas apresentam. Estudos relevantes referentes à produção de lipases por fermentação submersa envolvem o uso de resíduos agroindustriais objetivando diminuir o custo de produção do biocatalisador. Com base nestes aspectos, o o

6. "Estudo químico e atividades biológicas de extratos obtidos de culturas de Penicillium verrucosum Dierck" / Chemical study and biological activities of crude extracts obtained from different cultures of Penicillium verrucosum Dierck
The absence of an effective treatment for Chagas disease and Leishmaniasis stimulates the search for new active compounds. The enzymes GAPDH from T. cruzi and APRT from L. tarentolae are attractive targets for rational search of antiprotozoal agents, taking part in essential pathways of the pathogens. Natural products are rich in structural diversity and b

7. 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

8. Penicillium viridicatum, Penicillium verrucosum, and production of ochratoxin A.
The taxonomy of the important mycotoxigenic species Penicillium viridicatum and P. verrucosum was reviewed to clarify disagreements relating to the three P. viridicatum groups erected by Ciegler and coworkers (A. Ciegler, D. I. Fennell, G. A. Sansing, R. W. Detroy, and G. A. Bennett, Appl. Microbiol. 26:271-278, 1973) and the mycotoxins produced by them. Cul

9. Production of Penicillin by Fungi Growing on Food Products: Identification of a Complete Penicillin Gene Cluster in Penicillium griseofulvum and a Truncated Cluster in Penicillium verrucosum
Mycobiota growing on food is often beneficial for the ripening and development of the specific flavor characteristics of the product, but it can also be harmful due to the production of undesirable compounds such as mycotoxins or antibiotics. Some of the fungi most frequently isolated from fermented and cured meat products such as Penicillium chrysogenum and

10. Biochemical Characterization of Ochratoxin A-Producing Strains of the Genus Penicillium
In order to explore the biochemical scope of ochratoxin A-producing penicillia, we screened 48 Penicillium verrucosum isolates for the production of secondary metabolites. Fungal metabolites were analyzed by high-pressure liquid or gas chromatography coupled to diode array detection or mass spectrometry. The following metabolites were identified: ochratoxins

11. Ochratoxin A as the cause of spontaneous nephropathy in fattening pigs.
At a number of slaughters nephropathy and high ochratoxin A contents in kidneys have been observed in fattening pigs from two Swedish farms. In one herd the source of contamination was barley grown on the home farm and stored under such conditions that the growth of fungal species (Penicillium verrucosum var. verrucosum) producing ochratoxin A occurred, with

12. Antifungal Activity of Phenyllactic Acid against Molds Isolated from Bakery Products
Phenyllactic acid (PLA) has recently been found in cultures of Lactobacillus plantarum that show antifungal activity in sourdough breads. The fungicidal activity of PLA and growth inhibition by PLA were evaluated by using a microdilution test and 23 fungal strains belonging to 14 species of Aspergillus, Penicillium, and Fusarium that were isolated from baker
