Abstract 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 as sole carbon source at a wide concentration range (5–150 g/L). Maximum (47 IU/mL) (36 g/L) obtained initial 100 g/L. For this study, it of interest to valorize non-sterile table olive processing wastewat...

This report presents information on the state-of-the-art of metals recovery technologies to assist in identifying waste-management options for metalbearing sludges and wastewaters that may be regulated under the Resource Conservation and Recovery Act (RCRA). Only a few of the technologies addressed In this report (e.g., electrowinnlng, high-temperature metals recovery (HTMR]) are directly appli...

Microbial electrolysis cells (MECs) are potential candidates for sustainable wastewater treatment as they allow for recovery of the energy input by producing valuable chemicals such as hydrogen gas. Evaluating the effectiveness of MEC treatment for different wastewaters requires new approaches to quantify performance, and the establishment of specific procedures and parameters to characterize t...

The thriving agro-industry sector accounts for an essential part of the global gross domestic product, as need food and feed production is rising. However, industrial processing agricultural products requires use water at all stages, which consequently leads to vast amounts effluents with diverse characteristics, contain a significantly elevated organic content. This fact reinforces action cont...

Abstract The review aims to summarize the current knowledge on possibility of using non-conventional yeast species Yarrowia lipolytica in treatment and upgradation industry wastes. Importantly Y. is argued as generally recognized safe species, what indicates high application potential reviewed technologies. Special emphasis paper was given microbial processing food wastes, including fish animal...

Background: Due to the high content of nitrogen in the municipal wastewaters, this study evaluated the efficiency of Scenedesmus as an important microalgae in the removal of nitrate from wastewaters and its application as an appropriate culture medium. As algae have high resistance to temperature and pH changes, they can absorb low concentrations of nutrients and need simple low-cost technolog...

The valorization of food processing by-products, wastes and effluents is a challenging opportunity for the sustainable and competitive development of several relevant industrial sectors. One of the best examples of a biorefinery applied to plant processing wastes is that of the olive oil sector by-products including leaves and olive mill wastewaters (OMW). Management of OMW, in particular, has ...
