Microbial production of 1,3-Propanediol
Recent Pat Biotechnol 2008;2(3):191-7.PMID:19075867DOI:10.2174/187220808786240999.
The introduction of economic production processes for 1,3-Propanediol is a success story for the creation of a new market for a (bulk) chemical. The compound and its favorable properties have long been known; also the fermentation of glycerol to 1,3-Propanediol had been described more than 120 years ago. Nevertheless, the product remained a specialty chemical until recently, when two new processes were introduced, providing 1,3-Propanediol at a competitive price. Remarkably, one of the processes is in the field of white biotechnology and based on microbial fermentation, converting a renewable carbon source into a bulk chemical. This review covers the most important patents that led to the commercialization of bio-based 1,3-Propanediol. Furthermore, some of the recent developments towards a sustainable industry are addressed. Similar questions arise for a variety of products if they are to be produced bio-based in large scale. However, special emphasis is given to 1,3-Propanediol production.
Microbial production of 1,3-Propanediol
Appl Microbiol Biotechnol 1999 Sep;52(3):289-97.PMID:10531640DOI:10.1007/s002530051523.
1,3-Propanediol (1,3-PD) production by fermentation of glycerol was described in 1881 but little attention was paid to this microbial route for over a century. Glycerol conversion to 1,3-PD can be carried out by Clostridia as well as Enterobacteriaceae. The main intermediate of the oxidative pathway is pyruvate, the further utilization of which produces CO2, H2, acetate, butyrate, ethanol, butanol and 2,3-butanediol. In addition, lactate and succinate are generated. The yield of 1,3-PD per glycerol is determined by the availability of NADH2, which is mainly affected by the product distribution (of the oxidative pathway) and depends first of all on the microorganism used but also on the process conditions (type of fermentation, substrate excess, various inhibitions). In the past decade, research to produce 1,3-PD microbially was considerably expanded as the diol can be used for various polycondensates. In particular, polyesters with useful properties can be manufactured. A prerequisite for making a "green" polyester is a most cost-effective production of 1,3-PD, which, in practical terms, can only be achieved by using an alternative substrate, such as glucose instead of glycerol. Therefore, great efforts are now being made to combine the pathway from glucose to glycerol successfully with the bacterial route from glycerol to 1,3-PD. Thus, 1,3-PD may become the first bulk chemical produced by a genetically engineered microorganism.
1,3-Propanediol and its copolymers: research, development and industrialization
Biotechnol J 2010 Nov;5(11):1137-48.PMID:21058316DOI:10.1002/biot.201000140.
1,3-Propanediol (PDO), is now taking the transition from a traditional "specialty chemical" to a "commodity chemical". The market for PDO is growing rapidly as the technology develops. With the advancing PDO production technology, polytrimethylene terephthalate (PTT) as a new type of polyester has been applied in carpet and textile fibers, monofilaments, films, and nonwoven fabrics, and in the engineering thermoplastics area, because PTT has unique properties compared to other polymers such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). Responding to the environmental and sustainability factors, one- or two-step fermentation technology for PDO production has attracted people's attention. A novel flexible process for PDO production by using aerobic fermentation from glycerol or glucose has been developed and demonstrated with a facility capacity of 4000 t/year in a pilot plant. By using engineered Escherichia coli, 135 g/L PDO was obtained with glucose as feedstock. Since the bio-process of PDO production consumes 40% less energy and reduces greenhouse gas emissions by 20% versus petroleum-based propanediol, the bio-based PTT is more environmentally friendly and sustainable compared with the fossil fuel-based polymers, which made PTT more attractive with good prospects for the future.

1,3-Propanediol, a valuable bifunctional molecule, can be produced from renewable resources using microorganisms. It has several promising properties for many synthetic reactions, particularly for polymer and cosmetic industries. By virtue of being a natural product, relevant biochemical pathways can be harnessed into fermentation processes to produce 1,3-Propanediol. Various strategies for the microbial production of 1,3-Propanediol are reviewed and compared in this article with their promises and constraints. Furthermore, genetic and metabolic engineering could significantly improve product yields and overcome the limitations of fermentation technology. Present review gives an overview on 1,3-Propanediol production by wild and recombinant strains. It also attempts to encompass the various issues concerned in utilization of crude glycerol for 1,3-Propanediol production, with particular emphasis laid on biodiesel industries. This review also summarizes the present state of strategies studied for the downstream processing and purification of biologically produced 1,3-Propanediol. The future prospect of 1,3-Propanediol and its potential as a major bulk chemical are discussed under the light of the current research.
Lactobacillus reuteri growth and fermentation under high pressure towards the production of 1,3-Propanediol
Food Res Int 2018 Nov;113:424-432.PMID:30195537DOI:10.1016/j.foodres.2018.07.034.
Lactobacillus reuteri is a lactic acid bacterium able to produce several relevant bio-based compounds, including 1,3-Propanediol (1,3-PDO), a compound used in food industry for a wide range of purposes. The performance of fermentations under high pressure (HP) is a novel strategy for stimulation of microbial growth and possible improvement of fermentation processes. Therefore, the present work intended to evaluate the effects of HP (10-35 MPa) on L. reuteri growth and glycerol/glucose co-fermentation, particularly on 1,3-PDO production. Two different types of samples were used: with or without acetate added in the culture medium. The production of 1,3-PDO was stimulated at 10 MPa, resulting in enhanced final titers, yields and productivities, compared to 0.1 MPa. The highest 1,3-PDO titer (4.21 g L-1) was obtained in the presence of acetate at 10 MPa, representing yield and productivity improvements of ≈ 11 and 12%, respectively, relatively to the same samples at 0.1 MPa. In the absence of acetate, 1,3-PDO titer and productivity were similar to 0.1 MPa, but the yield increased ≈ 26%. High pressure also affected the formation of by-products (lactate, acetate and ethanol) and, as a consequence, higher molar ratios 1,3-PDO:by-products were achieved at 10 MPa, regardless of the presence/absence of acetate. This indicates a metabolic shift, with modification of product selectivity towards production of 1,3-PDO. Overall, this work suggests that HP can be a useful tool to improve of 1,3-PDO production from glycerol by L. reuteri, even if proper process optimization and scale-up are still needed to allow its industrial application. It also opens the possibility of using this technology to stimulate other glycerol fermentations processes that are relevant for food science and biotechnology.
