“…Moreover, Machado et al [200,201] studied the potential of basidiomycetous fungi isolated from tropical ecosystems to remove Remazol Brilliant Blue R (RBBR) (73) dye. Trogia buccinalis showed the highest RBBR (73) decolourization.…”

Abstract:One of the major problems facing the industrialized world today is the contamination of soils, ground water, sediments, surfacewater and air with hazardous and toxic chemicals. The application of microorganisms which degrade or transform hazardous organic contaminants to less toxic compounds has become increasingly popular in recent years. This review, with approximately 300 references covering the period [2005][2006][2007][2008], describes the use of fungi as a method of bioremediation to clean up environmental pollutants.

Studies have indicated the capacity of basidiomycetes to degrade recalcitrant organopollutants. However, the age of the fungal inoculum to obtain a more effective degradation has not been defined. The criterion used is total colonization of the substrate. Psilocybe castanella CCB444 and Lentinus crinitus CCB274 have been evaluated in soils containing hexachlorobenzene. In the present study, the physiological conditions of the fungal inocula were characterized on solid substrate (sugarcane bagasse, starch and soy flour). Colonization of the substrate, loss of organic matter, pH variation, organic carbon, total nitrogen, fungal biomass and enzymatic activity were evaluated over 30 days of incubation. Colonization of the substrate was almost complete after 20 days for both species, with about 90% of organic matter remaining on the substrates. The pH continued to be acid during incubation. The highest enzymatic production was observed at 10 days for L. crinitus and at 5 days for P. castanella. The fungi presented growth up to 30 days. The C/N ratio of the inocula showed little variation. The use among 10 and 15-day-old inoculum is adequate since sufficient nutrients are left to guarantee survival of the fungus, vigorous colonization of the substrate, a growing biomass and an active enzymatic system, thus permitting fungal growth in soil.

RESUMO O aumento das atividades industriais tem intensificado a poluição ambiental, promovendo a disposição inadequada de resíduos domésticos e industriais, principalmente resíduos perniciosos, implicando na contaminação do solo, ar, recursos hídricos superficiais e subterrâneos. Dentre as tecnologias mais utilizadas na recuperação dessas áreas degradadas, destaca-se a biorremediação, que tem, como agentes recuperadores, os micro-organismos. Portanto, o presente trabalho de revisão tem por objetivo abordar os principais aspectos da biorremediação por fungos – micorremediação de solos contaminados baseados nas diversas pesquisas já publicadas e disponíveis nos principais bancos de dados, tais como SciELO, LILACS, HighWire e PubMed. Essa biotecnologia vem sendo utilizada há vários anos em outros países e, em certos casos, apresenta menor custo e maior eficiência na remoção dos contaminantes do que as técnicas físicas e químicas que são atualmente utilizadas em escala comercial no tratamento de diversos resíduos e na remediação de áreas degradadas. Diante disso, é necessário que sejam realizados mais estudos para compreender os mecanismos de biorremediação mediada por micro-organismos, como ferramenta biológica no combate a poluição.
