1. First Asymmetric Reduction of Isatin by Marine-Derived Fungi
In this study, whole cells of marine-derived fungi were used to reduce isatin (1H-indole-2,3-dione) to dioxindole (3-hydroxyindolin-2-one) for 7 days at 32 °C. The screening showed that several strains could reduce isatin and produce the enantioenriched dioxindole. The best conversions were obtained by Cladosporium sp. CBMAI 1237 and Westerdykella sp. CBMAI

2. Penicillosides A and B: new cerebrosides from the marine-derived fungus Penicillium species
Abstract In the course of our ongoing effort to identify bioactive compounds from marine-derived fungi, the marine fungus, Penicillium species was isolated from the Red Sea tunicate, Didemnum species. Two new cerebrosides, penicillosides A and B were isolated from the marine-derived fungus, Penicillium species using different chromatographic methods. Their s

3. Caracterização da diversidade de fungos filamentosos associados a esponjas marinhas e avaliação da produção de lacase = : Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production / Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production
The ocean represents a promissing habitat in the search for new microorganisms, which may have the ability to produce enzymes of industrial interests different from that produced by their terrestrial counterparts. In this context, two samples of the marine sponge Dragmacidon reticulatum were collected on northern coast of São Paulo State, aiming at the char

4. 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

5. Estudos químicos e microbiológicos de microrganismos associados à esponja marinha Dragmacidon reticulatum, objetivando o isolamento de metabólitos secundários bioativos
Fungi are known as one of the most promising sources of unprecedent bioactive compounds, however, marine derived fungi are still very poorly studied. These microorganisms present high percentages of active metabolites and they are commonly isolated from marine invertebrates. At this study, the associated microbiota of the marine sponge Dragmacidon reticulatu

6. Study of polycyclic aromatic hydrocarbon (PAH) degradation and antimicrobial production by marine invertebrate derived fungi. / Estudo da degradação de hidrocarbonetos policíclicos aromáticas (HPAs) e da produção de antimicrobianos por fungos filamentosos isolados de invertebrados marinhos.
Seventy three fungi representatives of distinct taxonomic groups, isolated from cnidarians collected from north coast of São Paulo State, were submitted to RBBR dye decolorization tests and to MIC. Thirteen fungal selected from the decolorization test were submitted to pyrene and benzo[a]pyrene degradation assays. Seven fungi showed satisfactory PAH degrada

7. Resolução enzimática de álcoois racêmicos com lipase de Candida antarctica e redução de cetonas com fungos de origem marinha / Resolution enzymatic of alcohols secondary with lipase of Candida antartica and reduction of ketones with fungi of marine origin
This work carried out the enzymatic reactions of alcohols by using a lipase from immobilized Candida Antarctica (NOVOZYME 435). The alcohols used were: (RS)-1- (4-methoxyphenyl) ethanol (1a), (RS)-4-methyl-2-pentanol (3a), (RS)-2-methyl-3- hexanol (4a), (RS)-5-methyl-2-hexanol (5a), (RS)-2-octanol (6a), (RS)-3-heptanol (7a), (RS)-6-methyl-5-hepten-2-ol (8a)

8. Investigação da origem metabólica de derivados da esculetina ativos contra o vírus da SARS / Investigation of the metabolic origin of esculetin derivatives active against the SARS virus
Recently two compounds derived from esculetin have been isolated from the marine sponge Axinella cf. corrugata: the methyl ester of esculetin-4-carboxylic acid and the ethyl ester of esculetin-4-carboxylic acid. The latter displayed antiviral activity against the SARS virus. This project aimed the isolation and the growth of fungal strains associated to the

9. Reduction of derived from acetophenone with fungi of marine origin / Redução de derivados de acetofenonas com fungos de origem marinha
Neste trabalho realizou-se o primeiro estudo biocatalítico envolvendo reações de redução de cetonas com fungos de origem marinha. Foram utilizadas 7 cetonas comerciais como substratos e 8 fungos derivados marinhos como biocatalisadores. Os fungos foram isolados das esponjas marinhas Geodia corticostylifera (Trichoderma sp Gc1, Penicillium miczynskii Gc5

10. "Metabólitos secundários biologicamente ativos isolados de esponjas marinhas e do fungo Beauveria felina de origem marinha" / "Biologically active secondary metabolites from Marine Sponges and from the Marine-Derived fungus Beauveria felina"
In this work we report the chemical investigation of bioactive crude extracts obtained from four sponges and two fungal strains of marine origin. The crude extracts of three sponges species (Petromica ciocalyptoides, Topsentia ophiraphidites and Callyspongia sp.) displayed inhibitory activity towards the enzyme adenine fosforribosyl transferase of Leishmania

11. Characterization of Benthic Microbial Community Structure by High-Resolution Gas Chromatography of Fatty Acid Methyl Esters
Fatty acids are a widely studied group of lipids of sufficient taxonomic diversity to be useful in defining microbial community structure. The extraordinary resolution of glass capillary gas-liquid chromatography can be utilized to separate and tentatively identify large numbers of fatty acid methyl esters derived from the lipids of estuarine detritus and ma
