Abstract

Bacterial cellulose (BC) is an extracellular homopolymer produced by certain species of bacteria. It has demonstrated the potential as an alternative to plant cellulose with more appealing features such as unique nanostructure, high porosity, high crystallization index, high tensile strength, high water holding capacity, and a high degree of polymerization. These attributes facilitate BC utilization in various applications, ranging from the food industry, cosmetics, pharmaceutical, medical field, waste treatment, textile, and paper industry. Considering the advantages and wide range of applications, it is necessary to explore and improve the current industrial production to achieve a higher yield at a lower cost. This review article summarizes the BC properties and characteristics as well as its application in different fields. Furthermore, the potential of agricultural waste molasses for low-cost BC production is also discussed.

Abstract

Due to its relevance to businesses, employee engagement has been the subject of extensive study, and many scholars have linked it to burnout as its antipode. The work environment and team and co-worker interactions promote engagement and reduce burnout if well-managed. This study investigates the function of engagement as a mediator between the indirect effects of work environment, team, and co-worker relationships on employee burnout. Respondents are sourced from a public firm employee (Tbk). Using SEM-PLS, three hundred thirty-one obtained data are processed. The results indicate that burnout is negatively related to the work environment and team and co-worker relationships and that employee engagement somewhat mediates these relationships. To mitigate burnout, an additional study can investigate employee satisfaction and performance.
