1. ASYMMETRIC SULFOXIDATION OF ALBENDAZOLE TO RICOBENDAZOLE BY FUNGI: EFFECT OF pH
Albendazole (ABZ) is an anthelmintic drug used for the treatment of infectious diseases in veterinary and human medicine. This drug is a prochiral drug that after administration, is rapidly oxidized in the pharmacologically active sulfoxide metabolite, which is also known as ricobendazole (ABZSOX). ABZSOX has a stereogenic center and possibly two enantiomers

2. The semisynthetic landscape of aphidicolin: inspiration towards leishmanicidal compounds
Recentes estudos demonstraram que afidicolina, metabólito secundário do fungo endofítico Nigrospora sphaerica, apresenta alta atividade contra o protozoário Leishmania major. Apesar do promissor potencial leishmanicida, a afidicolina apresenta propriedades físico-químicas e perfil farmacocinético inadequado para terapêutica. Neste sentido, uma revis�

3. Fungi and bacteria associated with post-harvest rot of ginger rhizomes in Espírito Santo, Brazil
The objective of this study was to identify fungi and bacteria associated with the post-harvest rot of ginger rhizomes (Zingiber officinale Roscoe) in the Serrana region of Espírito Santo, Brazil. Rhizomes with symptoms of rot were sampled in the packing-house and in the field soon after harvest. In the packing-house, we report positive pathogenicity tests

4. Biosynthesis of aphidicolin proceeds via the mevalonate pathway in the endophytic fungus Nigrospora sphaerica
Previamente o fungo endofítico Nigrospora sphaerica foi identificado como um profícuo produtor do diterpeno bioativo afidicolina. Neste artigo foi realizado um estudo a fim de se verificar as melhores condições para a produção do diterpeno em meio Czapek. A fonte de açúcar (glicose e sacarose) e o tempo de incubação (4-15 dias) foram otimizados, pa

5. Fungos e bactérias associados às podridões pós-colheita de rizomas de gengibre no Espírito Santo / Fungi and bacteria associated with post-harvest ginger rot rhizomes in Espirito Santo
The rhizome of ginger (Zingiber officinale R.) is one of the most important spices in the world due to its use as feedstock in the food industry, pharaceuticals and cosmetics. The brazilian export of ginger has increased in recent years despite the damage caused by decay of rhizomes. Still unknown are the main etiological agents associated with postharvest r

6. Utilization of mixed cultures as a strategy to stimulate the biosynthesis of natural products by endophytic fungi / Utilização de culturas mistas como estratégia para estimular a biossíntese de produtos naturais por fungos endofíticos
O estudo das interações planta-microrganismos tem sido de grande interesse ao longo dos últimos anos. Atualmente, as interações que ocorrem entre microrganismos que vivem em estreita relação também vêm merecendo grande atenção, pois forças competitivas e mutualísticas podem induzir a produção de novos metabólitos bioativos. Portanto, estudar

7. Identificação e desenvolvimento de técnica alternativa de controle de fungos em sementes utilizadas no artesanato
Some seed samples of native plants from forestry, cerrado and savannas which are currently employed for the confection of handcrafts from several brazilian regions were valued as far as the phytosanitary aspects are concerned. The fungi overview and identification associated to the seeds as well as their symptoms were accomplished. Techniques of superficial
