Production of high-value functional vegetable juices from food co-products

Euglena gracilis produces paramylon, which is a feedstock for high-value functional foods and nutritional supplements. The enhancement of paramylon productivity is a critical challenge. Microalgae growth-promoting bacteria (MGPB) can improve microalgal productivity; however, the MGPB for E. gracilis remain unclear. This study isolated bacteria capable of enhancing E. gracilis growth and paramylon production under mixotrophic conditions. Enterobacter sp. CA3 and Emticicia sp. CN5 were isolated from E. gracilis grown with sewage-effluent bacteria under mixotrophic conditions at pH 4.5 or 7.5, respectively. In a 7-day E. gracilis mixotrophic culture with glucose, CA3 increased E. gracilis biomass and paramylon production 1.8-fold and 3.5-fold, respectively (at pH 4.5), or 1.9-fold and 3.5-fold, respectively (at pH 7.5). CN5 increased E. gracilis biomass and paramylon production 2.0-fold and 4.1-fold, respectively (at pH 7.5). However, the strains did not show such effects on E. gracilis under autotrophic conditions without glucose. The results suggest that CA3 and CN5 promoted both E. gracilis growth and paramylon production under mixotrophic conditions with glucose at pH 4.5 and 7.5 (CA3) or pH 7.5 (CN5). This study also provides an isolation method for E. gracilis MGPB that enables the construction of an effective E. gracilis–MGPB-association system for increasing the paramylon yield of E. gracilis.

Value Functional

This study examines the impact of Hanok experience on tourists’ attitude and behavioral intention using the experience economy ( Pine and Gilmore, 1998 ) and the experienced utility theory ( Kahneman et al., 1997 ). Specifically, the study explores how tourists’ experiences are associated with a Value-Attitude-Behavior (VAB) model in the context of a heritage tourism attraction such as Jeonju Hanok Village in South Korea. A total of 323 responses were examined using SEM analysis. The results revealed that educational, entertainment, and escapism experiences significantly influenced functional value. Functional value had a significant relationship with attitude, which was positively related to behavioral intention. The results indicate the interplay of tourists’ experiences with the VAB model. The study provides theoretical and practical implications for tourism and hospitality academics and practitioners.

The article proposes socio-psychological program for the development of anticipation of personality in terms of life changes, based on the principles of interconnection, continuous variability, dynamic equilibrium, irreversibility, relativity, self-organization, expansion, structuring, situational expediency, and differentiation in correctional development -, socio- and pathogenesis of the subjects. A significant increase in the level of personal-situational, spatial, general anticipatory ability in groups of young people and youth, increase in their internality of subjective control, general meaningfulness of life, focus on goals and effectiveness of life and the positive impact of these variables on prognostic competence and level of social maturity. According to the results of approbation and implementation of the program, the increase of attachment capacity is determined by its personal-situational and general components; dynamics of semantic systems at the content, structural, value, functional levels; constructive life strategies and internality, as well as the flexibility of coping behavior of the subjects in middle and late adulthood, which helped to increase their psychological well-being. The correctional and developmental work carried out within the program allowed to increase the level of anticipation ability in persons with manifestations of social maladaptation (according to the considered nosology), which ultimately affected the growth of achievement motivation, activity of life strategies; significant reduction of disintegration between value and accessibility in various spheres of life; multivariate forecasting and planning of events, in particular in the context of life changes, and to improve their social functioning in general. Key words: personality, mastery behavior, anticipation, social networks.

Online knowledge platforms have been undergoing a transformation from providing free knowledge to online paid knowledge (OPK). As customers play a key role in the sustainable development and success of the new business model, we focused on the factors that drive consumers’ online knowledge purchase intention. Drawing on the cognitive–affective–conative framework and customer value theory, we propose that consumers rationally evaluate the customer values of OPK in the cognitive stage, followed by generating trust and identification in the affective stage, then leading to a purchase decision. Six factors were extracted from three dimensions of customer value: Functional, emotional, and social values. The hypotheses were tested using survey data obtained from 504 respondents using structural equation modeling. The findings confirm that customer value and identification with the knowledge contributor significantly influence trust in OPK. Trust in OPK and identification with the knowledge contributor both significantly influence purchase intention, whereas trust in the platform neither influences consumers’ trust in OPK nor purchase intention. The findings of this study will help OPK platforms to increase their sales of knowledge products.
