1. Comparative Study of Degradation of Reactive Dyes and Decolorization and Detoxification in Aqueous Solution Applying DyP Peroxidases Isolated from Saccharomonospora viridis (SviDyP) and Thermobifida fusca (TfuDyp)
The wastewater that originates from the widespread usage of synthetic dyes in the industry have become a severe environmental problem. Several efforts have been made to develop new types of treatment which are capable of performing the degradation of the dyes from the environment. Within this scope, much attention has been drawn to enzymatic approaches, main

3. Complete genome sequence of a phthalic acid esters degrading Mycobacterium sp. YC-RL4
ABSTRACT Mycobacterium sp. YC-RL4 is capable of utilizing a broad range of phthalic acid esters (PAEs) as sole source of carbon and energy for growth. The preliminary studies demonstrated its high degrading efficiency and good performance during the bioprocess with environmental samples. Here, we present the complete genome of Mycobacterium sp. YC-RL4, which

4. Simultaneous Determination of Nonylphenol and Nonylphenol Ethoxylates in Wastewater Samples from Biodegradation Process by High Performance Liquid Chromatography Method
The degradation products of nonylphenol ethoxylates (NPnEO), nonylphenol (NP) and short-chain NPnEO are representative of environmental endocrine disruptors. They possess strong lipophilicity, toxicity, cumulative property and estrogenic effect. They can pollute the environment, cause body precocious, and induce the body's estrogen-sensitive cancer cell prol

5. BIODEGRADACION FUNGICA DE POLIURETANO RÍGIDO
Polyurethane (PU) is one of the most widely used polymer materials. This generates a serious environmental problem because of its poor biodegradability since most of the native microorganisms cannot use it as a source of nutrients. Several techniques involving mechanical and chemical processes have been used for its recovery and reuse; however, the problem o

6. FÁRMACOS QUIRAIS EM DIFERENTES MATRIZES AMBIENTAIS: OCORRÊNCIA, REMOÇÃO E TOXICIDADE
In recent decades, the occurrence of pharmaceuticals in the environment has been widely reported due to their high frequency and recalcitrance in many cases. Concerning the chiral pharmaceuticals (CPs) in environmental matrices, the stereochemistry is often neglected and enantiomers are determined together as unique molecules. However, it is well known that

7. Isolation and characterization of phenol degrading yeasts from wastewater in the coking plant of Zarand, Kerman
Abstract Phenol and phenolic compounds are environmental pollutants present in industrial wastewaters such as coal tar, oil refineries and petrochemical plants. Phenol removal from industrial effluents is extremely important for the protection of environment. Usually, phenol degradation is carried out by physicochemical methods that are costly and produce ha

8. Decolorization of azo dyes (Direct Blue 151 and Direct Red 31) by moderately alkaliphilic bacterial consortium
Abstract Removal of synthetic dyes is one of the main challenges before releasing the wastes discharged by textile industries. Biodegradation of azo dyes by alkaliphilic bacterial consortium is one of the environmental-friendly methods used for the removal of dyes from textile effluents. Hence, this study presents isolation of a bacterial consortium from soi

9. Carbaryl degradation by bacterial isolates from a soil ecosystem of the Gaza Strip
Abstract Carbaryl is an important and widely used insecticide that pollutes soil and water systems. Bacteria from the local soil ecosystem of the Gaza Strip capable of utilizing carbaryl as the sole source of carbon and nitrogen were isolated and identified as belonging to Bacillus, Morganella, Pseudomonas, Aeromonas and Corynebacterium genera. Carbaryl biod

10. Biodegradation of cypermethrin by immobilized cells of
Micrococcus sp. strain CPN 1Pyrethroid pesticide cypermethrin is a environmental pollutant because of its widespread use, toxicity and persistence. Biodegradation of such chemicals by microorganisms may provide an cost-effective method for their detoxification. We have investigated the degradation of cypermethrin by immobilized cells of

11. Bioremediation of dyes by fungi isolated from contaminated dye effluent sites for bio-usability
Biodegradation and detoxification of dyes, Malachite green, Nigrosin and Basic fuchsin have been carried out using two fungal isolates Aspergillus niger, and Phanerochaete chrysosporium, isolated from dye effluent soil. Three methods were selected for biodegradation, viz. agar overlay and liquid media methods; stationary and shaking conditions at 25 °C. Asp

12. Biodegradação bacteriana de compostos organoclorados
Due to their recalcitrant nature, organochlorides are already found in environment and the search for alternatives to eliminate these compounds such as biodegradation using native microorganisms is of great interest. A screening trial to select environmental bacteria able to degrade DDD, PCP and dieldrin was conducted. Among 14 isolates, the soil bacteria Ps
