Fermentative production of succinic acid (SA) from renewable carbohydrate feed-stocks can have the economic and sustainability potential to replace petroleum-based production in the future, not only for existing markets, but also new larger volume markets. To accomplish this, extensive efforts have been undertaken in the field of strain construction and metabolic engineering to optimize SA production in the last decade. However, relatively little effort has been put into fermentation process development. The choice for a specific host organism determines to a large extent the process configuration, which in turn influences the environmental impact of the overall process. In the last five years, considerable progress has been achieved towards commercialization of fermentative production of SA. Several companies have demonstrated their confidence about the economic feasibility of fermentative SA production by transferring their processes from pilot to production scale.

Kombucha is a popular fermented beverage that involves fermentation using a symbiotic culture of bacteria and yeast (SCOBY) and produces bacterial cellulose (BC). Carbon and nitrogen sources are essential in kombucha processing and BC production. However, studies on cost-effective BC production as an alternative source of leather have remained scarce.

The Warburg effect, which describes the fermentation of glucose to lactate even in the presence of oxygen, is ubiquitous in proliferative mammalian cells, including cancer cells, but poses challenges for biopharmaceutical production as lactate accumulation inhibits cell growth and protein production. Previous efforts to eliminate lactate production in cells for bioprocessing have failed as lactate dehydrogenase is essential for cell growth. Here, we effectively eliminate lactate production in Chinese hamster ovary and in the human embryonic kidney cell line HEK293 by simultaneous knockout of lactate dehydrogenases and pyruvate dehydrogenase kinases, thereby removing a negative feedback loop that typically inhibits pyruvate conversion to acetyl-CoA.

Miltiradiene serves as a pivotal precursor for the synthesis of numerous abietane-type diterpenes with important pharmacological activities. The endogenous mevalonate (MVA) pathway is tightly regulated in Saccharomyces cerevisiae, which limits the availability of precursors for the heterologous production of miltiradiene. In this study, the orthogonal isopentenol utilization pathway (IUP) was constructed and investigated for its adaptability with mitochondria and peroxisomes in S.

Background: Trichoderma species, known as biocontrol agents against plant diseases, contain diverse compounds, especially terpenoids, with various bioactivities. To facilitate the exploration of bioactive secondary metabolites of Trichoderma harzianum NTU2180, the OSMAC approach MS/MS molecular networking was applied in the current study.
Results: The feature-based molecular networking (FBMN) analysis showed that T.
