The Production of Ligninolytic Enzymes by Marine-Derived Basidiomycetes and Their Biotechnological Potential in the Biodegradation of Recalcitrant Pollutants and the Treatment of Textile Effluents

Diverse Metabolic Capacities of Fungi for Bioremediation

“…The attribute of marine fungi for producing laccase tolerant to high salinity and phenolics was aptly exploited by Divya et al [38] in case of Trichoderma viride Pers NFCCI-2745 isolated from an estuary polluted with phenolics. Similar applications of enzyme mediated bioremediation was demonstrated for decolorizing Remazol Brilliant Blue-R dye using three basidiomycetes isolated from marine sponges [39], and anthraquinone dye Reactive Blue 4 by C. unicolor, a marine white-rot basidiomycete. Gao et al [40] proposed that biostimulation and bioaugmentation could affect the biotransformation of persistent organic pollutants (POPs) such as PCB 118 by two marine fungi belonging to genus Penicillium in presence of maifanite [41].…”

Characterization of lignocellulolytic activities from fungi isolated from the deep-sea sponge Stelletta normani

“…isolated from the Brazilian sponges Amphimedon viridis and Dragmacidon reticulata have also been reported to be good producers of laccases [29]. With this in mind we focused our attention on the ligninolytic ability of the three fungal strains Cadophora , Emericellopsis and Pseudogymnoascus , particularly given that ligninolytic enzymes from marine-derived fungi are likely to find utility in biotechnological applications with alkaline pH, high salinity, low temperature, oligotrophic conditions, low water potential and hydrostatic pressure, such as amongst others- the treatment of coloured industrial effluent and bioremediation in high salt concentration environments, biofuel production, deinking, laundry and in the food industry [11,27,101]. …”

“…Indeed marine-derived fungi are well recognized as a good source of enzymes of potential industrial interest (cellulases, xylanases, phenol oxidases, laccases, etc. ); with strains exhibiting hydrolytic and oxidative activities being reported; for review see [27]. These fungal strains have predominantly been isolated from seawater, sediments, mangrove detritus and to a lesser extent from marine sponges [12,28,29].…”

“…One such report involves members of the phyla Ascomycota and Basidomycotina isolated from Haliclona simulans , which produced cellulase activities [32]. Xylanases from marine-derived fungi isolated from soft corals [33], marine sediments [34] and from shallow water marine sponges in Antarctica [35] have been reported, with many possessing interesting biochemical characteristics (optimal pH, temperature and thermostability) with potential utility in biotechnological applications such as bioremediation and in the textiles and paper industries [27,35,36]. The phenol oxidase and esterase activities from sponge-derived fungi are however to date, greatly under studied.…”

Prospecção de fungos derivados de esponjas marinhas na degradação/descoloração de poluentes ambientais.

“…pelos isolados DRAC1-9, DRR7-9, CeAC 2 e DRR4.1-6 em meio MB2% após 7 dias de cultivo a 28°C e 140 rpm. (BONUGLI-SANTOS et al, 2009;DA SILVA et al, 2008;PASSARINI et al, 2011a;PASSARINI;RODRIGUES, 2011b;MAGRINI, 2012), descoloração de corante têxtil (BONUGLI-SANTOS et al, 2012) e estudo da biodiversidade (DA SILVA et al, 2008;MENEZES et al, 2010;PASSARINI, 2008;PASSARINI et al, 2013) (BRINK et al 1997) Os elétrons necessários para a inserção de oxigênio no substrato molecular (R) são doados por um elétron separado do sistema doador. O sistema doador de elétron ou é um sistema de duas proteínas (adrenoxina e adrenoxina redutase) para P450 mitocondrial e procariótico ou uma proteína (citocromo P450 redutase, CPR 2 ) para enzimas citocromo P450 que estão localizadas no retículo endoplasmático (RE) (BRINK et al, 1997).…”
