SummaryThe relationships between growth, medium pH, assimilation of glucose and amino acids, presence or absence of lignocellulose in the medium, lignin solubilization, and the appearance of extracellular peroxidase activity were compared for two lignin-solubilizing actinomycetes, Streptomyces chromofuscus A2 and S. viridosporus T7A. In a mineral salt medium containing yeast extract and three amino acids S. chromofuscus A2 grew faster than S. viridosporus T7A. When d-glucose was added to this… 
Lignin Peroxidase from Streptomyces viridosporus T7A: Enzyme Concentration Using Ultrafiltration
TLDR
This work studied the concentration of lignin peroxidase (LiP), produced by Streptomyces viridosporus T7A, by ultrafiltration, in a laboratory-stirred cell, loaded with polysulfone (PS) or cellulose acetate (CA) membranes with molecular weight cutoffs (MWCO) of 10, 20, and 50 KDa.
Effect of aeration on lignin peroxidase production by Streptomyces viridosporus T7A
TLDR
Corn oil, used as carbon source, besides its antifoam properties, proved to be nonrepressive for enzyme production and aeration on lignin peroxidase production by Streptomyces viridosporus T7A was studied.
Degradation of lignin and other 14C-labelled compounds in compost and soil with an emphasis on white-rot fungi
Lignin, a recalcitrant compound, is one of the main components of wood, gramineous plants, and products made of these, such as mechanical pulp. The most efficient lignin degraders in nature are
Screening and Identification of some APPL (Acid Precipitable Polymeric Lignin) Producing Streptomycetes
Thirty seven actinomycetes isolates were isolated from Damietta soil using starch nitrate agar media. These isolates were screened for APPL (acid precipitable polymeric lignin) by using minimal
Purification of lignin peroxidase isoforms from Streptomyces viridosporus T7A by hydrophobic based chromatographies
Five lignin peroxidases ALiP-P3 isoenzymes from Streptomyces viridosporus T7A were separated by hydrophobic interaction chromatography. The most abundant isoenzyme was purified by reversed phase
The Biodegradation of Azo Dyes by Actinobacteria
Synthetic dyes have wide application in the textile, leather, pharmaceutical, cosmetic, paper and food industry. According to an estimate, global production of synthetic dyes is more than 700,000

Characterization of an extracellular lignin peroxidase of the lignocellulolytic actinomycete Streptomyces viridosporus
TLDR
This is the first report of a lignin peroxidase in a bacterium designated as ALiP-P3 and characterizations showed that this enzyme is a heme protein (Soret band, 408 nm) and a major component of the ligninolytic system of S. viridosporus T7A.
Extracellular Enzyme Activities during Lignocellulose Degradation by Streptomyces spp.: A Comparative Study of Wild-Type and Genetically Manipulated Strains
TLDR
This is the first report of such an enzyme in Streptomyces spp.
Lignin Degradation by Streptomyces viridosporus: Isolation and Characterization of a New Polymeric Lignin Degradation Intermediate
TLDR
The lignin origin of APPLs was confirmed by chemical analyses, which included acidolysis, permanganate oxidation, elemental analyses, functional group analyses, nuclear magnetic resonance spectroscopy, and C isotopic techniques.
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.
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.
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.
Microbial conversions of lignin to useful chemicals using a lignin-degrading Streptomyces
