Fourteen Streptomyces strains known to degrade lignocellulose were screened for their ability to decolorize three anthron-type dyes: Remazol Brilliant Blue R (RBBR), blue poly(vinylamine) sulfonate – anthraquinone dye (Poly B-411), and red poly(vinylamine) sulfonate – anthrapyridone dye (Poly R-478). The relationships between efficiency of dye decolorization and capacity to attack lignocellulose were examined. Good correlation was found between lignocellulose weight losses observed during… 
Redox-mediated decolorization of synthetic dyes by fungal laccases
TLDR
The data suggest that laccase/mediator systems are effective biocatalysts for the treatment of effluents from textile, dye or printing industries.
Decolorizing an anthraquinone dye by Phlebia brevispora: Intra‐species characterization
TLDR
The decolorization of RBBR by P. brevispora was characterized via UV spectrophotometry and GeneFishing technology revealed that two genes were differentially expressed in yellowish culture, suggesting that the decolorized color may be rapidly estimated at initial period of incubation.
Involvement of an extracellular H2O2-dependent ligninolytic activity of the white rot fungus Pleurotus ostreatus in the decolorization of Remazol brilliant blue R
TLDR
During solid-state fermentation of wheat straw, a natural lignocellulosic substrate, the white rot fungus Pleurotus ostreatus produced an extracellular H2O2-requiring Remazol brilliant blue R (RBBR)-decolorizing enzymatic activity, which behaved like an oxygenase possessing a catalytic metal center, perhaps heme.
Influence of aromatic substitution patterns on azo dye degradability by Streptomyces spp. and Phanerochaete chrysosporium
Twenty-two azo dyes were used to study the influence of substituents on azo dye biodegradability and to explore the possibility of enhancing the biodegradabilities of azo dyes without affecting their
Screening mitosporic fungi for organochlorides degradation
Fifty-five isolates of filamentous fungi were studied regarding their ability to decolorize Remazol brilliant blue R dye. The fungi were isolated from soil in the Baixada Santista region, which is
Effect of Fungal Laccase and New Mediators, Acetovanillone and Acetosyringone, on Decolourization of Dyes
TLDR
Several wood rotting fungi decolourized Remazol brilliant blue R (RBBR) and carminic acid (CA) and the addition of acetovanillone or ace- tosyringone (AS) intensified these processes:Decolourization was more extensive than in the experiment omitting these compounds.
Degrading ability of oligocyclic aromates by Phanerochaete sordida selected via screening of white rot fungi
TLDR
The ability of white rot fungi to degrade 3- or 4-ring PAHs (anthracene, phenanthrene, fluoranthene, pyrene) was determined and manganese peroxidase, the only extracellular ligninolytic enzyme detected during the cultivation, was evaluated.

Lignin-solubilizing ability of actinomycetes isolated from termite (Termitidae) gut.
TLDR
Of the assays used, total lignocellulose weight loss was most useful in determining overall bioconversion ability but not in identifying the best lignin-solubilizing strains.
Extracellular Enzyme Activities during Lignocellulose Degradation by Streptomyces spp.: A Comparative Study of Wild-Type and Genetically Manipulated Strains

This is the first report of such an enzyme in Streptomyces spp.
Microbial conversions of lignin to useful chemicals using a lignin-degrading Streptomyces
The lignocellulose-decomposing abilities of an actinomycete, Streptomyces viridosporus T7A, were studied in relation to the potential utilization of this strain for the bioconversion of lignin to
Screening for lignin-degrading actinomycetes and characterization of their activity against [14C]lignin-labelled wheat lignocellulose
TLDR
A sedimentation chamber and Andersen sampler were used to isolate a range of actinomycetes on selective and non-selective media and evidence for ligninolytic activity in representatives of several genera was obtained by assaying 14CO2 evolution from [14C]lignin-labelled wheat lignocellulose.
Production of Major Extracellular Enzymes during Lignocellulose Degradation by Two Streptomycetes in Agitated Submerged Culture
TLDR
Streptomyces viridosporus T7A and S. badius 252 were grown in 1 to 2% slurry cultures with mineral salts solution containing 0.6% yeast extract and 100/200 mesh ground and extracted corn lignocellulose and it was determined that peroxidases from both species consisted of four enzymes, with only one, the lignin peroxids having high activity.
Degradation of Kraft Indulin Lignin by Streptomyces viridosporus and Streptomyces badius
TLDR
Using a condensed industrial lignin essentially devoid of carbohydrates, Indulin AT, as the sole source of carbon, similar results were obtained: the growths of the bacteria were optimum at pH 7.5 to 8.5; yeast extract was a better source of nitrogen than NH(4)Cl; and the products of the depolymerization of Indulin were soluble, acid-precipitable polymers.
Production and Characterization of Polymeric Lignin Degradation Intermediates from Two Different Streptomyces spp
TLDR
Differences between the organisms were observed in the cultural conditions required for APPL production and in the time courses of APPL accumulation, indicating that differing mechanisms of lignin metabolism may exist in these two Streptomyces sp.
Lignocarbohydrate Solubilization from Straw by Actinomycetes
TLDR
Interestingly, this protein fraction was found to include active hydrolytic and oxidative enzymes involved in the degradation of lignocellulose, and specific enzyme activities were often increased in the acid-insoluble fractions of culture supernatants.
