1. Halotolerance, ligninase production and herbicide degradation ability of basidiomycetes strains
Fungi have been recently recognized as organisms able to grow in presence of high salt concentration with halophilic and halotolerance properties and their ligninolytic enzyme complex have an unspecific action enabling their use to degradation of a number of xenobiotic compounds. In this work, both the effect of salt and polyols on growth of the basidiomycet

2. 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. Degradation of lignosulfonic and tannic acids by ligninolytic soil fungi cultivated under icroaerobic conditions
Fungos isolados de solo foram avaliados quanto à habilidade em degradarem compostos derivados de lignina pela produção de enzimas ligninolíticas. Os ácidos lignosulfônicos e tânico foram usados separadamente como única fonte de carobono para cultivo dos fungos em 30 dias sob condições microaeróbias. Os fungos foram capazes de crescer e usar tais c

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. 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

10. 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

11. 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

12. Novas tendências para o tratamento de resíduos industriais contendo espécies organocloradas
The toxic character of organochloride compounds, their habitual presence in many industrial effluents, and mainly the low efficiency of the current remediation processes, are important aspects that have been promoted to study new degrading technologies. Among the great number of new physical and chemical alternatives, the photochemical and electrochemical pr
