Adsorption of silver on virgin and aged microplastics

(Corresponding) Kalčikova G., Jemec Kokalj A., Marolt G., Žgajnar Gotvajn A.
Topic: 
Microplastics in the marine environment
When microplastics enter aquatic ecosystems they are submitted to environmental aging which change their properties. Especially colonization by microorganisms alter their properties in term of density and adsorption properties. Hence the aim of the study was to evaluate the adsorption and leaching...Read more

Nitrification inhibition test of salty wastewater containing Tetrakishydroxymethyl phosphonium sulphate (THPS), formaldehyde and methanol using salt-adapted nitrifying bacteria, an alternative test method to ISO method

(Corresponding) Chhetri R., Kokkoli A., Karvelas S., Andersen H.
Topic: 
Wastewater treatment
Nitrification inhibition test is a standard method to test if the chemicals or samples received by wastewater treatment plant are toxic to the nitrifying bacteria in the wastewater treatment plant. Nitrification inhibition test based on ISO method ISO9509 or modified ISO9509 method (REFLAB method)...Read more

Use of a two-stage MBBR system for medium-strength dairy wastewater treatment

Katsara A., Iliopoulou A., Zkeri E., Aloupi M., Fountoulakis M., (Corresponding) Stasinakis A.
Topic: 
Wastewater treatment
A two-stage Moving Bed Biofilm Reactor (MBBR) system consisting of a methanogenic and an aerobic reactor in series was used for medium strength dairy wastewater treatment. An energy analysis was conducted for the methanogenic MBBR to investigate its autonomy and its potential to act as a...Read more

Application of quorum quenching to improve performance of membrane bioreactors: A comprehensive mini-review

(Corresponding) Banti D., Kampouris I., Yiangou M., (Corresponding) Samaras P.
Topic: 
Wastewater treatment
Membrane bioreactors (MBRs) have been widely used for wastewater treatment, presenting however a major disadvantage, the membrane fouling problem. The sludge microorganisms produce soluble microbial products (SMP) and extracellular polymeric substances (EPS) that lead to a formation of a sticky...Read more

Ciprofloxacin and sulfamethoxazole biotransformation products in anaerobic packed bed biofilm reactor applied to the sanitary sewage treatment

(Corresponding) Carneiro R., Sabatini C., Titato G., Ferreira T., Zaiat M., Santos-Neto Á.
Topic: 
Emerging pollutants
The presence of antibiotics in the environment has received a lot of attention in recent years due to their ability to promote and spread antimicrobial resistance. In this work, the biodegradation of the antibiotics ciprofloxacin (CIP) and sulfamethoxazole (SMX), as well as the concurrently...Read more

Membrane Aerated Biofilm Reactor: A Correlation between Biofilm Thickness and Removal of Pharmaceuticals and Endocrinal Disruptor Compounds

(Corresponding) Sanchez-Huerta C., Fortunato L., Leiknes T., Hong P.
Topic: 
Wastewater treatment
Removal of thirteen pharmaceuticals and endocrinal disruptor compounds via membrane aerated biofilm reactor was tested. MABR system demonstrated good management of nitrogenous nutrients. An increase in biofilm thickness enhanced the removal of analgesics, hormones, and disinfectants.

Influence of antibiotics on Arcobacter-like cells and their biofilm formation

(Corresponding) Šilha D., Švarcova K., Hofmeisterová L.
Topic: 
Antibiotic resistanse
Arcobacters belong to Gram-negative bacteria, the rod cells can be slightly curved into the shape or spiral. Their growth is typical in a microaerophilic environment, but some species are able to grow under aerobic or anaerobic conditions. The purpose of this study was to test the in vitro effect...Read more

Smoothie Drinks as a Possible Source of Resistant and Biofilm-forming Bacteria

(Corresponding) Šilha D., Syrová P., Syrová L., Janečková J.
Topic: 
Antibiotic resistance
Smoothie drinks are currently very popular drinks sold, especially in fast food establishments. However, smoothies are a significant source of microorganisms with a high level of antibiotic resistance. The study aimed to evaluate the microbiological quality of smoothies purchased in Eastern Bohemia...Read more
