Summary: A novel promoter engineering-based strategy was developed to create efficient PNP-mineralizing bacteria by introducing a complete PNP biodegradation pathway from Pseudomonas sp. strain WBC-3 into the genome of a biosafety and soil-dwelling bacterium Pseudomonas putida KT2440. Five strong promoters were identified from P. putida KT2440 and independently inserted into the genome to create a mutant strain with the highest PNP degradation rate and strong tolerance against high concentrations of PNP, demonstrating complete and efficient PNP mineralization. This strategy opens new avenues for creating efficient degraders for bioremediation.

Summary: This study successfully prepared three anhydrous cocrystals and three hydrate cocrystals using methods such as solvent-assisted grinding. The cocrystals were characterized through various techniques. The hydrogen bonding patterns between OBV and ECB in the cocrystals were similar to the ECB-benzoic acid cocrystal. The solubility and diffusion properties of the cocrystals were reduced compared to the native drug, mainly due to decreased concentration gradient and hydrophobic interactions.

Summary: Polyphthalamides (PPAs) are promising engineering thermoplastics used in demanding applications, with most commercially available PPAs currently derived from non-renewable petroleum resources. The synthesis of a semi-aromatic polyamide, PA6F, based on a bio-based monomer FDCA, using catalysts Ti-isopropoxide (TIPT) and Ti-citrate (TIC) resulted in improved molecular weights and glass transition temperatures. Incorporating hexamethylenediamine (HMDA) led to further enhancement in glass transition temperature, with PA6F showing high glass transition temperature and elastic modulus.

Summary: The present study aimed to evaluate the use of microalga Scenedesmus almeriensis for treating untreated urban wastewater. Two 12 m(3) raceway reactors, one supplemented with wastewater and the other with chemical fertilizer, were operated outdoors in a semi-continuous mode for eight months. The results showed that S. almeriensis could be produced in wastewater without affecting the photosynthetic apparatus, with an average productivity of 13 g center dot m(-2)center dot day(-1) in both systems. Moreover, the nutrient content of the wastewater, including nitrogen, phosphorous, and chemical oxygen demand, was reduced to meet European limitations, with average removal rates of 2.2, 0.2, and 3.0 g center dot m(-2)center dot day(-1) respectively. The raceway reactors demonstrated high potential for microalgal production and efficient biotreatment, proving to be robust and reliable. Additionally, an accurate model was developed to evaluate the effect of environmental conditions on biomass productivity in the clean system (R-2 = 0.9, p = 0.0002).
