“…As for the kinetics of styrene biodegradation, the literature data are very limited (Babaee et al 2010; Cox et al 1997; Das et al 2008; Jorio et al 2005; Jung and Park 2005), and the presented findings are often debatable. The works will be discussed in detail in the further part of the study, and the values of the kinetic parameters determined by the authors were set in Table 1.…”

The research into kinetics of styrene biodegradation by bacterial strain Pseudomonas sp. E-93486 coming from VTT Culture Collection (Finland) was presented in this work. Microbial growth tests in the presence of styrene as the sole carbon and energy source were performed both in batch and continuous cultures. Batch experiments were conducted for initial concentration of styrene in the liquid phase changed in the range of 5–90 g m−3. The Haldane model was found to be the best to fit the kinetic data, and the estimated constants of the equation were: μm = 0.1188 h−1, KS = 5.984 mg l−1, and Ki = 156.6 mg l−1. The yield coefficient mean value for the batch culture was 0.72 gdry cells weight (gsubstrate)−1. The experiments conducted in a chemostat at various dilution rates (D = 0.035–0.1 h−1) made it possible to determine the value of the coefficient for maintenance metabolism md = 0.0165 h−1 and the maximum yield coefficient value . Chemostat experiments confirmed the high value of yield coefficient observed in the batch culture. The conducted experiments showed high activity of the examined strain in the styrene biodegradation process and a relatively low sensitivity to inhibition of its growth at higher concentrations of styrene in the solution. Such exceptional features of Pseudomonas sp. E-93486 make this bacterial strain the perfect candidate for technical applications.

“…Different kinds of activated sludge processes are used for wastewater treatment because of the unique operational, economical, and environmental advantages associated with them [1][2][3]. In these three phase processes, the microbial community -in the form of a solid phase -is responsible for biodegradation of pollutants, and availability of enough oxygen for biological reactions is considered a critical factor which emphasizes the importance of an appropriate air supply to the bioreactor.…”

“…While some porous materials exhibit promising results in sensing VOCs in solution, fluorescence sensing of trace VOCs in vapor is still challenging on account of their low vapor pressure at room temperature 25,26 . Styrene is a common VOC that is widely used as a precursor for the synthesis of rubber, plastic products, resins, and polyester in synthetic industries [27][28][29] . As potentially carcinogenic species, styrene vapor can cause harm, such as the irritation of skin, eyes, and respiratory system [30][31][32] .…”

Developing novel lanthanide metal-organic frameworks (Ln-MOFs) to rapidly and reliably differentiate both metal ions in solution and volatile organic compounds (VOCs) in vapor is highly challenging. Here, we describe versatile Eu 3+ /Tb 3+ -MOFs based on a flexible ligand. It is noteworthy that the film fabricated using bimetallic Eu 0.47 Tb 0.63 -MOF and polyvinyl alcohol could serve as an easy and convenient luminescent platform for distinguishing different metal ions and VOCs. The luminescent film exhibits notable fingerprint correlation between the metal ions/VOCs and the emission intensity ratio of Eu 3+ /Tb 3+ ions in Ln-MOFs. As a result, the bimetallic Ln-MOFs show fast recognition of Fe 3+ ion with a response time of <10 s, and can effectively probe styrene vapor within 4 min. Since the developed Ln-MOF film is stable and reliable, this work presents a promising strategy to explore luminescent platforms capable of effectively sensing different metal ions and VOCs.
