Formation of volutin granules inCorynebacterium glutamicum [PDF]

FEMS Microbiology Letters, 2005
Volutin granules are intracellular storages of complexed inorganic polyphosphate (poly P). Histochemical staining procedures differentiate between pathogenic corynebacteria such as Corynebacterum diphtheriae (containing volutin) and non-pathogenic species, such as C. glutamicum. Here we report that strains ATCC13032 and MH20-22B of the non-pathogenic C.

Engineering 2‐Pyrone‐4,6‐Dicarboxylic Acid Production Reveals Metabolic Plasticity of Poplar

Plant Biotechnology Journal, EarlyView.
ABSTRACT Woody biomass is a promising source of fermentable sugars for biofuels and bio‐based chemicals, but its industrial use is limited by the costly biorefinery process. A viable strategy to reduce costs involves enhancing both biomass processability and the generation of high‐value co‐products.

响应面法优化重组谷氨酸棒杆菌G-BC 产脂肪酸的培养条件Optimization of culture conditions for fatty acid production of recombinant Corynebacterium glutamicum G-BC by response surface methodology

Zhongguo youzhi, 2022
乙酰辅酶A羧化酶是谷氨酸棒杆菌中调控脂肪酸合成的关键酶。为了研究乙酰辅酶A羧化酶α亚基（accBC）基因对脂肪酸合成的影响，以accBC表达的菌株重组谷氨酸棒杆菌G-BC为材料，研究了诱导剂异丙基-β-D-硫代半乳糖苷（IPTG）浓度、培养时间、培养温度对重组谷氨酸棒杆菌G-BC脂肪酸产量的影响，并通过响应面法优化了重组谷氨酸棒杆菌G-BC产脂肪酸的培养条件，同时与原始菌株脂肪酸产量进行了对比。结果表明：重组谷氨酸棒杆菌G-BC产脂肪酸的最佳条件为诱导剂浓度1 mmol/L 、培养时间20 h ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Biomanufacturing Potential of Streamlined Cells

Biotechnology and Bioengineering, Volume 122, Issue 12, Page 3309-3318, December 2025.
ABSTRACT A series of Escherichia coli streamlined strains was developed by removing the expression of genes encoding extracellular structures and unessential enzymes. The streamlined strains exhibited improved metabolic performance, including lower overflow metabolism and ATP maintenance coefficient, as well as a higher growth rate, compared to their ...

Succinic Acid Production by Engineered Mannheimia succiniciproducens and Its Use in Chemoenzymatic Poly(Butylene Succinate) Synthesis

Biotechnology and Bioengineering, Volume 122, Issue 12, Page 3393-3405, December 2025.
Succinic acid is produced by the fermentation of metabolically engineered Mannheimia succiniciproducens, purified, and used to synthesize poly(butylene succinate) using a two‐step process that involves the esterification of succinic acid and ethanol, followed by enzymatic transesterification of diethyl succinate and 1,4‐butanediol.
