Biorecovery of metal sulfides from leachates obtained through zinc-carbon battery recycling
(Corresponding) Retka J., Uhrynowski W., Zhendong Y., Karczewska-Golec J., Bajda T., Drewniak L., Debiec-Andrzejewska K.
Topic:
Solid waste management
One of the most commonly used methods of recycling of spent zinc-carbon batteries is hydrometallurgical leaching with sulfuric acid. The technology is highly efficient and enables the recovery of the majority of deposited metals. Unfortunately it also generates leachates that remain after the...Read more

Rapid bacteria detection in drinking water samples with on-chip Mach-Zehnder Interferometers
(Corresponding) Angelopoulou M., Petrou P., Misiakos K., Raptis I., Kakabakos S.
Topic:
Drinking water safety
Drinking water contamination by pathogenic bacteria poses a great danger for public health, since according to WHO 5 million deaths are associated to water related diseases annually. To safeguard drinking water quality, several techniques for bacteria detection, such as culturing and plating, ELISA...Read more

Biodegradation of pharmaceuticals by bacteria isolated from estuarine environment - cleanup technologies through nature based processes
(Corresponding) Fernandes J., Duarte P., Almeida C., Carvalho M., Mucha A.
Topic:
Emerging pollutants
New sustainable technologies are needed to tackle pharmaceuticals contamination in different environmental compartments. Bioremediation technology, using native microorganisms with capacity for partial or complete elimination of contaminants, can be considered. This work investigated the capability...Read more
Bacterial inactivation and study of damages in subcellular level during disinfection of aqueous samples
(Corresponding) Gounaki I., Lironi M., Venieri D.
Topic:
Advanced oxidation processes
The objectives of the current study were i) to investigate the effectiveness of ozonation and UVA photocatalysis for the inactivation rate of representative bacterial strains, which are considered important for public health and ii) to study damages in subcellular level, in terms of disinfection...Read more
Study of the potential of Rhodococcus strains for degradation of the pesticide Glyphosate (Roundup)
Gerginova M., Peneva N., (Corresponding) Alexieva Z.
Topic:
Soil and groundwater contamination and remediation
The experiments were aimed at studying the tolerance of the studied strains of Rhodococcus sp. M1 and Rhodococcus sp. D1 to the presence of Glyphosate (N- (phosphonomethyl) glycine) in the culture medium. A rich organic medium (YEPD), a mineral medium (VD) with 1% glucose and a mineral medium...Read more
Effect of Castanea sativa plantation age on soil bacterial communities
(Corresponding) Alvarez-Lopez V., Ferreiro-Dominguez N., Mosquera-Losada R.
Topic:
Agroforestry, forest and agricultural sustainability
Soil microbial communities are involved in key processes of forest ecosystems that include decomposition of organic matter, cycling of nutrients or formation of structure. The composition and diversity of these communities depend on a large number of factors such as humidity, pH, nutrient levels, C...Read more
Evaluation of the potential of four microalgal-bacterial symbiotic association on wastewater treatment and lipid accumulation
Talapatra K., Mittal V., (Corresponding) Ghosh U., Gautam R.
Topic:
Environmental biotechnology and bioenergy
Microalgae-bacteria symbiotic systems have demonstrated greater benefits over the pure culture of microalgae. The existence of certain bacteria will increase the quality of sewage purification and also reduce the associated high capital cost for maintaining the pure culture of microalgae. In this...Read more
Application of solar photo-Fenton oxidation coupled with granular activated carbon as a viable option for the removal of contaminants of emerging concern in the urban wastewater of India
Karaolia P., Korelidou A., (Corresponding) Fatta-Kassinos D.
Topic:
Advanced oxidation processes
It has been estimated that approximately 62 billion litres of sewage are generated every day in India, with only 37% of sewage being treated (Saxena et al., 2021). Wastewater treatment issues such as dysfunctional UWTPs with many of them operating at low service levels compared to the design...Read more
Peracetic acid disinfection: An effective way to reduce antibiotics resistant bacteria from raw hospital wastewater
(Corresponding) Chhetri R., Sanchez Urbina D., Lindholst S., Rickers C., Elkær T., Gade H., Skaarup J., Andersen H.
Topic:
Wastewater treatment
Risk of infection from antibiotic resistant bacteria from wastewater to the workers in the plant can be reduced by disinfecting wastewater. Peracetic acid (PAA) was used to disinfect the raw wastewater from hospital in pilot scale experiment. Batch experiment was conducted in parallel to confirm...Read more
Regeneration of dissolved Fe(II) from Fenton sludge at a microbial fuel cell using a novel biocathode
(Corresponding) Wang G., Tang K., Jiang Y., Andersen H., Zhang Y.
Topic:
Advanced oxidation processes
Fenton reactions are widely applied for degrading recalcitrant pollutants, but the resulting ferric sludge remains a challenge. A novel concept for regenerating Fe(II) solution at pH 6 from ferric sludge generated in neutral Fenton is proposed. A microbial fuel cell (MFC) with biocathode and...Read more
