“…However, utilization of such a valuable product as honey for microbial fermentation can be controversial and unprofitable. Nowadays, it is required that the modern biotechnology fulfills the principles of circular economy and converts feedstock into value-added chemicals ( Hernández-Pérez et al, 2020 ). Due to this fact, in the presented work, crude glycerol obtained from the biodiesel industry was chosen as a substrate for KYNA production using Y. lipolytica as a microbial factor for its biosynthesis.…”

Yarrowia lipolytica yeast are able to produce kynurenic acid—a very valuable compound acting as a neuroprotective and antioxidant agent in humans. The recent data proved the existence of the kynurenine biosynthesis pathway in this yeast cells. Due to this fact, the aim of this work was to enhance kynurenic acid production using crude glycerol and soybean molasses as cheap and renewable carbon and nitrogen sources. The obtained results showed that Y. lipolytica GUT1 mutants are able to produce kynurenic acid in higher concentrations (from 4.5 mg dm−3 to 14.1 mg dm−3) than the parental strain (3.6 mg dm−3) in the supernatant in a medium with crude glycerol. Moreover, the addition of soybean molasses increased kynurenic acid production by using wild type and transformant strains. The A-101.1.31 GUT1/1 mutant strain produced 17.7 mg dm−3 of kynurenic acid in the supernatant during 150 h of the process and 576.7 mg kg−1 of kynurenic acid in dry yeast biomass. The presented work proves the great potential of microbial kynurenic acid production using waste feedstock. Yeast biomass obtained in this work is rich in protein, with a low content of lipid, and can be a healthy ingredient of animal and human diet.

“…The concept of bioeconomy possesses interpretative flexibility in ways that can be employed to the specific challenges and meet the needs of diverse actors and objectives (Meyer, 2017;Barañano et al, 2021;Mijailoff and Burns, 2023;Trigkas and Karagouni, 2023). Recent theoretical developments acknowledge the technology-based implementation pathway to bioeconomy (Leitão, 2016;Meyer, 2017;Hernández-Pérez et al, 2020;Bröring and Thybussek, 2023).…”

The bioeconomy seeks to efficiently transform biomaterials into value-added products to achieve circularity. A circular bioeconomy is a circular carbon economy based on bio-based resources. There is a dearth of information in the literature about how psychological factors affect public acceptance of the bioeconomy, especially in Africa, where the adoption of bioeconomy is scant. Addressing this gap, this study characterized bioeconomy as a low-carbon bio-based technological innovation to combat climate change and developed the Bioeconomy Technology Acceptance Model (BTAM) to explain the effects of individual-level factors on public acceptance of bioeconomy and investigated it in a survey (N = 465) using questionnaires that were carried out in Lagos, Nigeria, in 2022. The respondents were chosen by proportional stratified random sampling, and descriptive statistics, Pearson’s correlation coefficient, and structural equation modeling were used to analyze the data obtained. The strong influence of perceived usefulness from bioeconomy and intention to accept bioeconomy in BTAM suggests that the Technology Acceptance Model (TAM) is suitable for predicting public acceptance of bioeconomy. Considering the strong influence of belief about climate change on the perceived usefulness of bioeconomy and intention to accept it in this study, it is imperative to promote climate change education among Africans to accelerate acceptance of bioeconomy on the continent. The identified psychological factors provide a reference for scholars, policymakers, and manufacturers to effectively develop individual-oriented intervention strategies and promotion schemes to enhance acceptance of bioeconomy in Africa in particular and other climes where there is not yet widespread acceptance of circular bioeconomy.
