A dual route for anaerobic succinate production was engineered into Corynebacterium glutamicum. The glyoxylate pathway was reconstructed by overexpressing isocitrate lyase, malate synthase and citrate synthase. The engineered strain produced succinate with a yield of 1.34 mol (mol glucose)−1. Further overexpression of succinate exporter, SucE, increased(More)
A novel marine strain representing efficient degradation ability toward brown algae was isolated, identified, and assigned to Bacillus weihaiensis Alg07. The alga-associated marine bacteria promote the nutrient cycle and perform important functions in the marine ecosystem. The de novo sequencing of the B. weihaiensis Alg07 genome was carried out. Results of(More)
2-Deoxy-d-ribose 5-phosphate aldolase (DERA) accepts a wide variety of aldehydes and is used in de novo synthesis of 2-deoxysugars, which have important applications in drug manufacturing. However, DERA has low preference for non-phosphorylated substrates. In this study, DERA from Klebsiella pneumoniae (KDERA) was mutated to increase its enzyme activity and(More)
Previously published studies have proposed fatigue life prediction models for dense graded asphalt pavement based on flexural fatigue test. This study focused on the fatigue life prediction of High Modulus Asphalt Concrete (HMAC) pavement using the local strain-stress method and direct tension fatigue test. First, the direct tension fatigue test at various(More)
An engineered strain for the conversion of d-fructose to allitol was developed by constructing a multi-enzyme coupling pathway and cofactor recycling system in Escherichia coli. d-Psicose-3-epimerase from Ruminococcus sp. and ribitol dehydrogenase from Klebsiella oxytoca were coexpressed to form the multi-enzyme coupling pathway for allitol production. The(More)
