1. Leaf extracts of Casearia sylvestris and Casearia decandra affect growth and production of ligninolytic enzymes in wood decay basidiomycetes
RESUMO Basidiomicetos de podridão branca são capazes de deteriorar madeira e atuar como patógenos de árvores. A flora tropical é uma importante fonte de compostos antifúngicos ecologicamente seguros, entretanto, o conhecimento de como extratos vegetais afetam a fisiologia fúngica é limitado. Portanto, neste trabalho foi investigada a influência de e

2. Ligninolytic fungus Polyporus sp. S133 mediated metabolic degradation of fluorene
ABSTRACT This study aimed to investigate the impact of nonionic surfactants on the efficacy of fluorine degradation by Polyporus sp. S133 in a liquid culture. Fluorene was observed to be degraded in its entirety by Polyporus sp. S133 subsequent to a 23-day incubation period. The fastest cell growth rate was observed in the initial 7 days in the culture that

3. Degradação de HPAs e produção de enzimas ligninolíticas por fungos basidiomicetos derivados de esponjas marinhas / PAHs degradation and ligninolytic enzymes production by marine-sponge-derived basidiomycetes fungi
Hidrocarbonetos Policíclicos Aromáticos (HPAs) são poluentes ambientais oriundos de fontes naturais e antropogênicas, caracterizados por suas propriedades mutagênicas e carcinogênicas e persistência no ambiente. Fungos basidiomicetos de degradação branca têm sido extensivamente estudados devido à sua habilidade em degradar uma ampla variedade de c

4. Lignin degradation, ligninolytic enzymes activities and exopolysaccharide production by Grifola frondosa strains cultivated on oak sawdust
Fourteen strains of Grifola frondosa (Dicks.) S. F. Gray, originating from different regions (Asia, Europe and North America) were tested for lignin degradation, ligninolytic enzyme activities, protein accumulation and exopolysaccharide production during 55 days of cultivation on oak sawdust. Lignin degradation varied from 2.6 to7.1 % of dry weight of the oa

5. Estudo da produção de enzimas ligninolíticas por Ceriporiopsis subvermispora / Study of the prodution of ligninolytic enzymes by Ceriporiopsis subvermispora
This work involved the research and definition of the culture conditions that maximize the production of manganese peroxidase (MnP) and laccase (Lac) by C. subvermispora, a white-rot fungus studied in biopulping industrial processes. The study involved submerged or static cultures with immobilized mycelium in polyuretane foam in complex or defined medium, an

6. Biodegradação de polietileno tereftalato (PET) por fungos ligninoliticos / Biodegradation of polyethylene tereftalate by ligninolytic fungi
In 1977, polyethylene terephthalate (PET), a plastic derived from petroleum, started to be used as raw material for packaging material and engineering plastics. However, under an environmental point of view, the use of plastics is considered problematic because of their high durability and high volume when present in domestic and industrial solid wastes. Thi

7. Fungi biodegradation of vinasse from industrial sugarcane processing / Biodegradação de vinhaça proveniente do processo industrial de cana-de-açúcar por fungos
Vinasse is a residue resulting from the production of alcohol after pulp fermentation and distillation of the wine, ensuing from 10 to 15 liters for each liter of ethanol produced. This high colored effluent is a by-product rich in nutrients, mainly organic matter, having a high pollutant potential when disposed in the environment. Lignolytic fungi can be ut

8. Biodegradação de efluente têxtil por Pleurotus sajor-caju
Effluents generated by the textile industry are of environmental concern because of the presence of dyes with complex molecular structure, which confer them recalcitrant characteristics. Indigo is one of the most widely used dyes within the textile sector and studies have suggested that edible fungi may be capable of its biodegradation. A textile effluent wa

9. Degradation of dioxinas and furanos policlorados for ligninolíticos basidiomecetos fungos and its application in biorremediação process. / Degradação de dioxinas e furanos policlorados por fungos basidiomicetos ligninoliticos e sua aplicação em processo de biorremediação.
Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) are compounds produced as by-products, unintentionally, in industrials processes and combustion processes. Municipal solid waste incineration is one major source these compounds. The isomers with chlorines substituted in the 2,3,7,8 positions are thought to cause risks to human hea

10. Avaliação de fungos com potencial de degradação com diuron e pyrithiobac-sodium
Pyrithiobac-sodium is a post-emergence herbicide for early application, registered for broadIeaves control in cotton crops. Diuron is a phenylurea used for weed control on non-crop areas and selectively on crops such as cotton, sugarcane, citrus and pineapple. At present, this herbicide is one of the IDOst used in Brazil. Experiments were carried out in gree

11. Fungos degradadores de compostos organicos recalcitrantes sob condições microaerobia e anaerobia
The industrial activities of modern society produce great amounts of toxic compounds, which persist in rivers, soils and oceans, causing disturbance to ecosystems. Owing to an extracellular and non-specificenzymatic system produced by whiterot fungi, degradation of these xenobióticos became a viable alternative for environmental bioremediation. Such lignino

12. Estudo da degradação de polimeros sinteticos de importancia industrial por linhagens fungicas
This work describes the action of basidiomycetes fungi on the degradability of the four main synthetic polymers used in food packaging: polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) and another synthetic polymer, a polyurethane foam (PU). The microorganisms were grown in the salts liquid medium, pH 6.8, cont
