“…Costa et al (2005) reported that no laccase was detected and MnP play a major role in the process of sugarcane bagasse pretreatment with C. subvermispora. Fernandes et al (2005) reported that only MnP was detected in the process of Eucalyptus grandis delignification with Phellinus flavomarginatus. Lignin degradation is a complicated process.…”

“…35 Some mechanistic insight has been gained into these processes, and some immediate chemical inducers, such as 2,5-dimethoxybenzyl alcohol (for laccases) 36 and iron (for general mRNA regulation and iron acquisition), 37 have been identified. Little is known, however, about the role of water activity 38 and light 39 on cellular differentiation. Candidate genes controlling light responses are now being searched, using opsin or phytochrome motives or by insertional mutagenesis.…”

“…39 Substrate effects on the composition of the exo-proteome were reported recently. 38 Insufficient causal correlations are available as yet to design optimized culture systems for the production of volatile flavours. In the case of submerged-grown F. hepatica, the data presented show that the biotechnologically favoured submerged variant is not promising for this purpose, while surface cultivation suffers from a number of technical and operational drawbacks, such as substrate transport limitations, downstream and monitoring problems.…”

Cultures of Fistulina hepatica DSMZ 4987 were grown submerged in standard nutrition solution (SNS) or on oak wood powder (OWP). After cell disintegration, the volatile constituents were isolated by continuous liquid-liquid extraction (CLLE) and investigated by high-resolution gas chromatography coupled to mass spectrometry (HRGC-MS). The surface cultures produced 53 major volatile compounds, while 39 major volatile compounds were found in the submerged cultures. The surface cultures produced several aldehydes, methoxybenzenoids and terpenes, which were absent in the submerged cultures. A strong mushroom aroma was emitted by the surface cultures only. Twenty compounds, mainly long-chain fatty acids and methyl esters thereof, and short chain aliphatic alcohols, were common to both systems.

“…As pesquisas relacionadas à utilização de fungos causadores de podridão branca têm aumentado a atenção nos últi-mos anos devido ao reconhecimento da sua importância em diferentes áreas da ciência como, por exemplo, na biodegradação de compostos xenobióticos (Rabinovich et al, 2004;Tortella et al 2005;Patel et al, 2009) e decomposição de resí-duos madeireiros (Yadav et al, 2002;Luna et al, 2004;Fernandes et al, 2005;Alfenas et al, 2007;Van Heerden et al, 2008).…”

“…O processo de avaliação de microrganismos quanto ao potencial biodegradador pode ser realizado com base, por exemplo, no crescimento micelial (Yadav et al, 2002), densidade micelial ou vigor micelial (Abreu et al, 2007), perda de massa (Fernandes et al, 2005;Abreu et al, 2007), produção de biomassa (Paes et al, 2002) e atividade enzimática (Wesenberg et al 2003, Rabinovich et al, 2004Tang & Zhong, 2004).…”

O objetivo deste trabalho foi avaliar o potencial degradador in vitro de fungos causadores de podridão branca em serragem de clones de eucalipto. As espécies fúngicas de podridão branca utilizadas nos testes in vitro foram: Pycnoporus sanguineus, Phellinus gilvus e Schizophyllum commune. O experimento foi realizado em arranjo fatorial 3 x 3, disposto em delineamento inteiramente casualizado. Os parâmetros analisados foram: diâmetro do crescimento micelial (cm), velocidade de crescimento (cm dia -1 ), densidade micelial dos isolados fúngicos e perda de massa da serragem (%). Os isolados Phellinus gilvus e Pycnoporus sanguineus apresentaram maior velocidade de crescimento e resultaram em maior perda de massa da serragem em relação ao Schizophyllum commune. Pycnoporus sanguineus apresentou maior adensamento micelial que os demais isolados em todos os clones testados. Dentre os clones testados, o 2361 foi o que resultou em menor velocidade de crescimento dos isolados fún-gicos e menor perda de massa da serragem, mas favoreceu a formação de micélio mediamente a fortemente adensado em todos os isolados fúngicos. Dos isolados testados, Pycnoporus sanguineus e Phellinus gilvus foram os mais eficientes na degradação in vitro da serragem de eucalipto.

The white-rot fungi species tested were: Pycnoporus sanguineus, Phellinus gilvus and Schizophyllum commune. The experiment was carried out in factorial arrangement 3 x 3, displayed in a completed randomized design. The analysed parameters were: diameter of the mycelial growth (cm), speed of growth (cm day -1 ), mycelial density of the fungal isolate and loss of sawdust mass (%). The isolated Pycnoporus sanguineus and Phellinus gilvus presented higher speed growth and resulted in higher loss of sawdust mass when compared to Schizophyllum commune. Pycnoporus sanguineus presented the highest mycelial density in all clones tested. Clone 2361 resulted in the smallest fungal isolate growth and smaller loss of sawdust mass, but it favored the formation of moderately and highly dense mycelial in all isolates. The most efficient in in vitro degradation of eucalyptus sawdust was achieved with Pycnoporus sanguineus and Phellinus gilvus.
