A University of Washington study evaluates sustainable bioplastics from algae, focusing on sugar kelp-derived materials, their seawater biodegradability and comparative life cycle environmental impacts relative to polylactic acid (PLA).The algal approach offers a feedstock-independent alternative that is naturally biodegradable, addressing concerns about reliance ...
It is defined as the controlled microbiological treatment of biodegradable plastic waste under aerobic (composting) or anaerobic (biogasification) conditions. ...
Plastic pollution is a well-known worldwide problem, and the topic has been receiving increasing attention in recent years. Biodegradable plastics can be broken down by microbes, chewed up and turned into biomass, water and carbon dioxide under aerobic conditions or carbon dioxide and methane in the absence of oxygen. ...
Modern Water Treatments In modern times, advances in technology have built on the foundation of older treatments. For example, aerobic processes have long been the mainstay of wastewater treatment, particularly for sewage and other waste streams high in organic or biodegradable content. In aerobic processes, microorganisms that thrive in ...
It is thought that the organic removal resulted from aerobic and anaerobic biodegradation on the sponge medium. The sulfate concentration increased 1.5–1.9-fold in the first layer, with almost no subsequent change in the second to fourth layers. ...
Aerobic wastewater treatment ranges from the simple to revolutionary technologies like MABR, which saves energy and is ideal for decentralized treatment Aerobic wastewater treatment takes many forms, but fundamentally it’s a biological process widely used in the treatment of both domestic and industrial wastewater, particularly waste streams high in ...
This, in turn, leads to more rapid increases in dissolved oxygen and aerobic biodegradation. In addition, these larger injection volumes have proven HBS well systems to be a viable treatment technology for large free product plumes. ...
The cumulative carbon dioxide release over a 28 day exposure period was used to calculate the percentages of biodegradation. As no significant levels of biodegradation were recorded AGRAGEL is not readily biodegradable under aqueous, aerobic conditions. Biodegradation in compost Biodegradability ...
The positive interactions are clear when microalgae provide, through photosynthesis, the oxygen necessary for aerobic bacteria to biodegrade organic pollutants, consuming in turn the carbon dioxide released from the bacterial activity. ...
A laboratory-scale biomass inhibition study showed that aerobic biodegradation removed gabapentin in addition to adsorption. ...
Anthropogenic contaminants, including known and suspected EDC, were detected in surface water and sediment collected from 2 streams and 2 lakes in Rocky Mountains National Park (ROMO). The potential for aerobic EDC biodegradation was assessed in collected sediments using 6 14C‐radiolabeled model compounds. Aerobic microbial mineralization of ...
The article presents a mathematical model of biofilm growth for aerobic biodegradation of a toxic carbonaceous substrate. Modelling of biofilm growth has fundamental significance in numerous processes of biotechnology and mathematical modelling of bioreactors. ...
If and when they are formed, these compounds are readily biodegradable under both aerobic (Tabak et al., J. WPCF 53: 1503-1518, 1981) and anaerobic conditions (Eichler and Schink, Arch Microbiol 143: 60-66, 1985; Platen and Schink, Arch Microbiol 149: 136-141, 1987) and are not expected to migrate significant distances from anaerobic treatment zones. ...
Unlike phenol, the stable molecular structure of NHCs make them nearly impossible to degrade under aerobic or anaerobic condition. In this paper, biodegradation of phenol and NHCs as carbon sources for denitrification was studied in a laboratory-scale anoxic reactor. ...
To this end, the pharmacokinetic literature, the University of Minnesota's Biocatalysis/Biodegradation Database Pathway Prediction System aerobic microbial degradation software, and photolysis literature pertaining to β‐blockers and SSRIs were used to determine their most likely TPs formed via human metabolism, aerobic ...
The change in biotoxicity was monitored with Escherichia coli and Vibrio fischeri. The improvement in biodegradability during oxidation was demonstrated through 5-day biochemical oxygen demand/chemical oxygen demand ratio and aerobic biological treatment. ...
The purpose of studying the biodegradability of pharmaceutical compounds is to evaluate their behaviors in relation to the treatment processes generally used in domestic and industrial wastewater treatment plants. The antibiotic norfloxacin was found to be a recalcitrant compound. The studies conducted showed norfloxacin removal rates of 12% and 18% when biomasses from treatments ...
Natural biodegradation of TCE was observed under both aerobic and anaerobic conditions. No significant effects were observed on the intrinsic biodegradation of TCE under aerobic conditions with the presence of the dispersants. ...
Batch and continuous experiments were adopted to study the biodegradation of TA in synthetic wastewater. In anoxic batch experiments TA began to degrade gradually after EG was depleted completely. However, in aerobic batch experiments the biodegradation curves of TA in the presence of EG were almost identical to those of TA in the absence of EG. ...
Bisphenol-A (BPA) biodegradation was studied in a membrane bioreactor under aerobic conditions. The effects of the initial BPA concentration and initial chemical oxygen demand (COD) concentration on BPA biodegradation were investigated. The degradation process followed a first-order kinetic (more than 98% of BPA was removed) with a ...
