Secondary metabolites are divided into three classes: phenolic, terpenoid, and nitrogenous
compounds. Phenolic compounds are also known as polyphenols and include tannins …

Tannins are secondary metabolites that are widely distributed in the plant kingdom. They act
as growth inhibitors for many microorganisms: they are released upon microbial attack …

High salt seriously destroys the stable interactions among key functional species of activated
sludge, which in turn limits the performance of high-salinity wastewater biological treatment …

Microorganisms have great potential to control environmental pollution, particularly
industrial sources of water pollution. Currently, leather industry is regarded as the most …

Aspergillus niger B60 was screened for the first time toward extracellular tannase and gallic
acid production by submerged fermentation using synthetic media supplemented with tannic …

Fungal strains; resistant to Chromium (Cr) and tannic acid were isolated from tannery
effluents and rDNA gene sequentially identified as Aspergillus niveus MCC 1318 …

Tannases are valuable industrial enzymes used in food, pharmaceutical, cosmetic, leather
manufacture and in environmental biotechnology. In this study, 15 fungal isolates were …

Tannery effluents contain high amounts of polluting chemicals, such as salts and heavy
metals released often to surface waters. New economic and eco-friendly purification …

Talaromyces minioluteus belongs to the section Trachyspermi, has a worldwide distribution
and has been found on various substrates, especially on various (stored) food commodities …

Photocatalytic degradation of condensed tannins is a more efficient and cleaner way than
traditional microbial and chemical degradations. In this work, the ultrasonic-assisted UV light …
