Special Issue Information

Dear Colleagues,

The new circular bio-based economy explores the full potential of all types of sustainably sourced biomass, crop residues, industrial side-streams, and wastes by transforming them into a wide spectrum of value-added products. The development of large-scale bioprocesses for the bioconversion of biomass resources into environmentally friendly biofuels, chemicals, and materials is required to answer timeless societal challenges. Cost-effective microbial conversion processes of renewable feedstock into biofuels and biochemicals are of utmost importance for the establishment of a robust bioeconomy. Therefore, the transition to a sustainable bio-based economy requires further scientific research and innovation to reach those goals. Integrated yeast biorefinery processes have recently gained relevance in envisaging the conversion of forest and agro-industrial residues into environmentally friendly products currently produced by the petrochemical industry. For all these reasons, this is a very active and exciting area of R&D.

This Special Issue aims to gather the most recent and original research and review papers on the identification, development, and exploitation of robust, metabolically promising, and genetically engineered yeast strains envisaging the transition to a circular bio-based economy. Saccharomyces cerevisiae is a major cell factory for which vast biological knowledge and genetic tools are available. However, the exploitation of non-Saccharomyces yeasts has recently been gaining momentum, making this large and heterogeneous group desirable for the synthesis of a wide range of added-value products.

Papers on the identification, exploitation, and development of robust, metabolically promising, and genetically engineered conventional and non-conventional yeast strains for the production of bioproducts are welcome. Papers exploring functional and comparative genomics analyses for understanding the physiological genomics of yeasts as cell factories and the development of bioprocesses, especially those dedicated to the valorization of bio-residues and production of added value products by yeasts, are also welcome.

Exploration of yeast diversity for the sustainable production of biofuels, in particular biodiesel, is gaining momentum in recent years. However, sustainable, and economically viable bioprocesses require yeast strains exhibiting: (i) high tolerance to multiple bioprocess-related stresses, including the various chemical inhibitors present in hydrolysates from lignocellulosic biomass and residues; (ii) the ability to efficiently consume all the major carbon sources present; (iii) the capacity to produce lipids with adequate composition in high yields. More than 160 non-conventional (non-Saccharomyces) yeast species are described as oleaginous, but only a smaller group are relatively well characterised, including Lipomyces starkeyi, Yarrowia lipolytica, Rhodotorula toruloides, Rhodotorula glutinis, Cutaneotrichosporon oleaginosus and Cutaneotrichosporon cutaneum. This article provides an overview of lipid production by oleaginous yeasts focusing on yeast diversity, metabolism, and other microbiological issues related to the toxicity and tolerance to multiple challenging stresses limiting bioprocess performance. This is essential knowledge to better understand and guide the rational improvement of yeast performance either by genetic manipulation or by exploring yeast physiology and optimal process conditions. Examples gathered from the literature showing the potential of different oleaginous yeasts/process conditions to produce oils for biodiesel from agro-forestry and industrial organic residues are provided.
