Summary: In this study, a strain capable of efficiently degrading N,N-dimethylformamide was isolated, and a method for pollutant removal coupled with poly(3-hydroxybutyrate) accumulation was developed. The strain possessed the necessary genes for poly(3-hydroxybutyrate) synthesis. Optimal conditions for poly(3-hydroxybutyrate) production were determined through the investigation of nutrient supplementation and various physicochemical variables. Furthermore, N,N-dimethylformamide was found to enable similar poly(3-hydroxybutyrate) accumulation, serving as a special nitrogen source. This study provides a new strategy for resource utilization of specific pollutants and wastewater treatment.

Summary: This study investigates the supercritical carbon dioxide foaming characteristics of the biodegradable polymer P(3HB-co-4HB) for environmentally friendly packaging materials. The effect of the 4HB composition on the foaming conditions, such as pressure and temperature, is studied, and the resulting foam density and expansion ratio are evaluated. Increasing the 4HB content reduces the crystallinity and tan delta value required for foam cell growth. Lower foaming temperatures are needed to maintain a suitable tan delta value. However, foaming is not possible when the 4HB content exceeds 50% due to a high tan delta value. Crystalline P(3HB-co-4HB) with low 4HB content results in lower foam density and higher expansion ratio compared to non-crystalline P(3HB-co-4HB) with high 4HB content. The addition of a chain extender slightly increases the expansion ratio by reducing crystallinity and tan delta, most effectively with a 4HB content of 16%.

Summary: The feasibility of producing poly(3-hydroxybutyrate) (PHB) from free sugars in fruit wastes was evaluated in Paraburkholderia sacchari fed-batch bioreactor fermentations. Different conditions including initial sugar concentration, carbon to inorganic phosphorus (C/IP) ratio, IP addition during feeding, and volumetric oxygen transfer coefficient (k(L)a) were investigated to enhance PHB production. The highest intracellular PHB accumulation (66.6%), PHB concentration (108.3 g/L), productivity (3.28 g/(L.h)), and yield (0.33 g/g) were achieved under the conditions of 40 g/L initial sugars, C/IP 26.5, 202.6 h(-1) k(L)a value, and 20% IP supplementation in the feeding solution. There was no significant effect of different microbial mass harvesting time on PHB properties, except for a decrease in tensile strength over time.

Summary: Microalgae are cell factories that can be used to produce renewable energy, food, feed, pharmaceuticals, and nutraceuticals. The challenges of mass cultivation and biomass recovery limit the industrial application of microalgae. Cultivating microalgae in wastewater has been encouraged for sustainable bioeconomy. Wastewater from the food industry provides a less-toxic growth medium for low-cost microalgal biomass production. Microalgae are potential biocatalysts for wastewater bioremediation and offer a universal alternative for resource recovery from wastewater.

Summary: The recent studies have shown that micro/nano plastics and antimicrobial resistance genes have harmful effects on the environment and human health. However, there is a lack of research on the interactions between these two factors and their combined influence. The interaction of microplastics has led to the formation of new plastics such as plastiglomerates, pyroplastics, and anthropoquinas. Additionally, the occurrence of microplastics has been found to contribute to the emergence of antimicrobial resistance genes and other pollutants such as polyaromatic hydrocarbons and pesticides. The excessive use of antibiotics following the Covid outbreak has further exacerbated the detrimental effects on human health. This study highlights the relationship between microplastics and antibiotic resistance generation, evaluates the factors of uncontrolled antibiotic use and negligent plastic consumption, and provides future research prospects to accurately assess the serious environmental occurrence of these pollutants.

Summary: This study aimed to develop a bioprocess for the production of 2,5-Furandicarboxylic acid (FDCA), a platform chemical and monomer used in plastic industries. A bioprocess was successfully developed using pineapple peel-derived 5-(Hydroxymethyl)furfural (HMF) as a precursor for FDCA production. The bioprocess involved the use of Aspergillus flavus APLS-1 to convert HMF into FDCA, with a yield that can be further improved in the future. This study is the first to report the production of FDCA from pineapple waste.

Summary: This study compares the performance of a nanofiber device and a resin column for antibody capture. The nanofiber device has a larger housing volume and lower binding capacity, but comparable eluate purity to the resin column. It shows high stability, can be used for multiple cycles, and maintains consistent eluate quality when scaled up. The use of a single nanofiber device can significantly reduce costs compared to a resin column, especially when the number of batches is limited.

Summary: Fed-batch cell culture processes are commonly used in biomanufacturing due to their simplicity and applicability in cGMP environments. However, the challenge lies in the changing physiochemical conditions within the bioreactor as the cell density changes. Traditional response surface models (RSMs) are commonly used for optimization but are limited by their use of time-invariant factors. Dynamic RSM (DRSM) models can predict the time-dependent impact of process inputs, allowing for optimization of process operations that change over time.
