“…The tolerance to higher pH could probably be related to the genetic characteristics because ZH-1 was isolated from micro-alkaline soil. After determinations of the glycerol concentration, fermentation time and pH, the glycerol molar conversion rate reached 0.497 mol•mol −1 from the original 0.34 mol•mol −1 , the molar yield of 1,3-PD to glycerol was consistent with those reported in literatures and those previously reported [7] [20]- [22]. Y. M et al studied fed-batch of a K. pneumoniae strain on combining biodiesel production by lipase with microbial production of 1,3-PD using a hollow fiber membrane.…”

“…Y. M et al studied fed-batch of a K. pneumoniae strain on combining biodiesel production by lipase with microbial production of 1,3-PD using a hollow fiber membrane. The molar yield of 1,3-PD to glycerol of 0.47 mol•mol −1 was obtained [7]. Another study on bioconversion of raw glycerol into 1,3-PD by K. pneumoniae showed that the molar yield of 1,3-PD to glycerol of 0.41 mol•mol −1 [23].…”

“…However, the production of 1,3-PD via microbial fermentation can be achieved under mild conditions (for example, moderate reaction condition, room temperature and atmospheric pressure) [6]. In recent years, due to the massive use of bio-diesel, crude glycerol is used as a typical industrial waste resulting from its excess [7]. Therefore, the rational use of crude glycerin can reduce the cost of production of 1,3-propanediol fermentation so as to accelerate the commercialization of microbial fermentation method.…”

Abstract1,3-Propanediol is a promising renewable resource produced by microbial production. It is mainly used in many synthetic reactions, particularly applied to the polymer synthesis and cosmetics industry. We described here the isolation of strain ZH-1, which has the ability of high production with 1,3-propanediol, from Fenhe River in China. It was classified as a member of K. pneumoniae after the study of phenotypic, physiological, biochemical and phylogenetic (16S rDNA). The initial glycerol concentration, fermentation time and pH value of strain ZH-1 were determined to be 50 g•L −1 , 36 h and 8.0. Under these conditions, the practical yield of 1,3-PD was 18.53 g•L −1 and a molar yield (mol 1,3-PD mol Glycerol −1 ) of 1,3-propanediol to glycerol of 0.497. In addition, we found that for the strain ZH-1, the optimum grown pH was 9.0, so we can determine that it is a new member of alkali-resistant strains.

“…As noticed from these studies, the use of microorganisms capable of degrading/converting crude glycerol has been a major strategy proposed (Pagliaro et al, 2007). The predominant type of work reported in recent years employs pre-selected and/or already established strains of microorganisms for glycerol-bioconversion processes (Mu et al, 2008;Rymowicz et al, 2010;Gungormusler et al, 2011;Ashby et al, 2011), which is relevant in view of the urge of developing biotechnologies able to efficiently cope with the waste of biodiesel production (Yazdani and Gonzalez, 2007;Dobson et al, 2012). However, the screening for new strains of microorganisms showing greater or more rapid degradation of crude glycerol, or even displaying novel metabolic features in terms of value-added compounds they can generate directly from growth on this residue, should not be relegated in this context.…”

“…To process the crude glycerol residue based upon economic and environmentally sustainable methods that lead to value-added products, several approaches have been developed (e.g., Mu et al, 2008;Min et al, 2010;Posada et al, 2011;Ashby et al, 2011;Varrone et al, 2012). As noticed from these studies, the use of microorganisms capable of degrading/converting crude glycerol has been a major strategy proposed (Pagliaro et al, 2007).…”

ABSTRACT. The increasing world production of biodiesel has resulted in an accumulation of crude glycerol as the major byproduct. This could be used as carbon source for industrial microbiology, with economic and environmental advantages for the biodiesel industry. We explored an Atlantic Rainforest soil sample to search for crude glycerol-degrading microorganisms. Microcosms of this soil were established containing minimal medium + 8% crude glycerol (w/w); the biological activity was measured by respirometry. High CO 2 levels were found in some of the crude glycerol microcosms, suggesting the activity of microorganisms capable of degrading this residue. In an attempt to isolate and cultivate these microorganisms in vitro, aliquots of the soil suspension were plated on minimal medium containing 10% crude glycerol (v/v). Out of 19 morphologically distinct isolates, 12 bacteria and 6 yeasts were identified by PCR from universal primers 16S and 26S rDNA, respectively. Optical density readings revealed growth differences among cultures. Microbial crude-glycerol degraders from rainforest soil Two yeasts and three bacteria with distinct growth profiles stood out and appeared to have potential for liquid fermentation of crude glycerol. The yeasts adapted rapidly, but produced relatively little biomass. Opposite tendencies were found in the bacteria. Amplicon sequencing placed the bacterial isolates as close to Staphylococcus arlettae, Pseudomonas citronellolis, and Bacillus megaterium, and the yeasts to Trichosporon moniliiforme and Meyerozyma guilliermondii. We concluded that these species have potential for use in crude glycerol bioreactors and for bioremediation processes.
