Stress modulation as a means to improve yeasts for lignocellulose bioconversion

The second-generation (2G) fermentation environment for lignocellulose conversion presents unique challenges to the fermentative organism that do not necessarily exist in other industrial fermentations. While extreme osmotic, heat, and nutrient starvation stresses are observed in sugar- and starch-based fermentation environments, additional pre-treatment-derived inhibitor stress, potentially exacerbated by stresses such as pH and product tolerance, exist in the 2G environment. Furthermore, in a consolidated bioprocessing (CBP) context, the organism is also challenged to secrete enzymes that may themselves lead to unfolded protein response and other stresses. This review will discuss responses of the yeast Saccharomyces cerevisiae to 2G-specific stresses and stress modulation strategies that can be followed to improve yeasts for this application. We also explore published –omics data and discuss relevant rational engineering, reverse engineering, and adaptation strategies, with the view of identifying genes or alleles that will make positive contributions to the overall robustness of 2G industrial strains

Unlocking the Relationship Between Lean Leadership Competencies and Industry 4.0 Leadership Competencies: An ISM/Fuzzy MICMAC Approach

The ascension of technology and evolution of productive processes indicate that leadership must evolve to direct organizations in the transition to the fourth industrial revolution. The main purpose of this article is to study the existing relationship between the competencies of Lean leaders and the competencies of current leaders in Industry 4.0. A systematic literature review was conducted, and we identified 18 Lean leadership competencies and 6 Leadership 4.0 competencies. Our results show the relationship between the leadership competencies using an interpretive structural modeling approach. The analysis of the driving power and dependence power of Lean and Industry 4.0 leadership competencies was performed with the fuzzy Matriced' Impacts Croisés Multiplication Appliquée á un Classement approach. A structural model was elaborated upon and showed the hierarchy among the investigated competencies, indicating the ones that should be prioritized. The principal conclusion of our study is that Lean leaders' competencies can sustain the competencies that should be developed in Industry 4.0 leaders. Additionally, strong synergy among the competencies from both approaches is observed. To the best of our knowledge, our study is the first to present the relationship between Lean competencies and Industry 4.0 leadership competencies. The results obtained in this article may guide the shaping of new leaders who work in an Industry 4.0 environment. \textcopyright 1988-2012 IEEE

The Driving and Dependence Power between Lean Leadership Competencies: An Integrated ISM/Fuzzy MICMAC Approach

Lean Manufacturing (LM) is about cultural change at all levels of an organization, which can be seen as the essence of leadership. This study aims to present a list of the main Lean leadership competencies with validated definitions and propose a practical roadmap to Lean leadership development and training. A Systematic Literature Review (SLR) was conducted to achieve this goal in which the Lean leadership competencies were identified. The Interpretive Structural Modelling (ISM) approach established the relations among the leadership competencies and result in a structural model that could be used for Lean leadership development. The analysis of leadership competencies' driving power and dependence power was done using the fuzzy Matriced' Impacts Croisés Multiplication Appliquée á un Classement (MICMAC), which improved the reliability of research. This study contributes to Lean leadership literature by proposing a validated roadmap to Lean leader development and training. A structural model was developed that shows the hierarchy among the competencies and indicates the ones that should be prioritized. Besides, the result shows that the main ways to improve a Lean leader are attending to the shop floor and developing self-awareness. Furthermore, a strong synergy among all competencies was observed, reinforcing the fact that Lean must be an endless journey of improvement. To the best of our knowledge, our study is the first to present the relationship between Lean leadership competencies. In addition, the results may guide the development of new leaders who work in Lean environments. \textcopyright 2021 Informa UK Limited, trading as Taylor & Francis Group
