Kluyvera cryocrescens sepsis in a preterm infant.
Kluyvera cryocrescens, formerly accepted as a benign saprophytic microorganism, is an opportunistic pathogen and its infection is very rare in humans. This report describes a preterm infant born at 30 weeks of gestational age and successfully treated for K. cryocrescens sepsis in the 3rd week of life. To our knowledge, this is the first case of K. cryocrescens sepsis in a newborn. The potential...
متن کامل1,3‐Propanediol production from glycerol by a newly isolated Trichococcus strain
A coccal bacterium (strain ES5) was isolated from methanogenic bioreactor sludge with glycerol as the sole energy and carbon source. Strain ES5 fermented glycerol to 1,3-propanediol as main product, and lactate, acetate and formate as minor products. The strain was phylogenetically closely related to Trichococcus flocculiformis; the rRNA gene sequence similarity was 99%. However, strain ES5 doe...
متن کاملBiotechnological production of 1,3-propanediol from crude glycerol
1,3-Propanediol (1,3-PD) is one of the important products used in chemical industry, in particular for polyesters production (e.g. polyethers and polyurethanes). Using crude glycerol for producing 1,3-PD is a good solution from the economical as well as ecological point of view. Glycerol produced by cleavage of natural fats can be microbially converted to 1.3-propanediol by, among others, Citro...
متن کاملHypothetical glycerol pathways of newly isolated strains capable of 1,3-propanediol production.
Study presented here demonstrates the ability of three newly isolated strains, obtained from environmental probes (manure, bottom sediment, and food waste) and identified as Clostridium bifermentans, Clostridium butyricum, and Hafnia alvei, to synthesize 1,3-propanediol (1,3-PD), organic acids (such as lactic, acetic, fumaric, succinic, and butyric acids), and ethanol from glycerol. The product...
متن کاملMicrobial conversion of glycerol to 1,3-propanediol by an engineered strain of Escherichia coli.
In an effort to improve industrial production of 1,3-propanediol (1,3-PD), we engineered a novel polycistronic operon under the control of the temperature-sensitive lambda phage P(L)P(R) promoter regulated by the cIts857 repressor and expressed it in Escherichia coli K-12 ER2925. The genes for the production of 1,3-PD in Clostridium butyricum, dhaB1 and dhaB2, which encode the vitamin B(12)-ind...
