“…4). The pesticide p,p'-DDT gradually degrades to p,p'-DDE and p,p'-DDD through biological and photochemical transformations under both aerobic and anaerobic conditions (Guenzi and Beard, 1976;Yao et al, 2006;Purnomo et al, 2008;Thomas et al, 2008). Furthermore, a ratio (DDE + DDD)/RDDT > 0.5 is due to long term weathering (Li et al, 2006;Jiang et al, 2009).This was the case in all sections, so we concluded that origin of DDT inputs to the Gulf of Batabanó was historical and that a significant degradation has occurred.…”

“…For instance, Gloeophyllum genus, Daedalea genus, and Fomitopsis genus showed a high ability to degrade DDT affording 1,1-dichloro-2,2-bis (4-chlorophenyl) ethane (DDD), 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (DDE), and 4,4-dichlorobenzophenone (DBP) as metabolic products [133].…”

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.

“…The application of fungi for the biodegradation of recalcitrant chemicals has been widely studied [16][17][18][19][20]. This interest is based on the fungal capacity to degrade several molecules of organic pollutants and other persistent toxic substances using nonspecific enzymes [21][22][23][24][25][26]. Basidiomycetes, including the genus Pleurotus, can degrade lignocellulosic materials through extracellular ligninolytic enzymes, such as laccase, manganese peroxidase and lignin peroxidase.…”

The herbicide atrazine (2-chloro-4-ethylamine-6-isopropylamine-s-triazine) is extensively used for weed control in sugarcane crops. The application of fungi for the biodegradation of xenobiotics has been studied with promising results. Therefore, atrazine degradation mediated by Pleurotus ostreatus INCQS 40310 was evaluated, and the involvement of ligninolytic enzymes along with the degradation process was also investigated. To promote high degradation percentages and rates, a fractional factorial experimental design was first used to determine the most significant medium components for atrazine degradation. This strategy improved atrazine degradation from 39.0% to 71.0% after 15 days, with the formation of different metabolites. Afterward, a 3 2 full factorial design was performed using the variables selected in the first part of this study. The salts FeSO 4 and MnSO 4 showed significant influence in the percentages and the rates of atrazine degradation. The medium optimization resulted in 90.3% and 94.5% of atrazine degradation after 10 days and 15 days, respectively. Although laccase activity was measured during the degradation process, it was not possible to correlate laccase activity with atrazine degradation. The results demonstrated the efficiency of P. ostreatus INCQS 40310 for atrazine degradation, thus demonstrating the potential of this fungus as a bioremediation agent.
