Characterization of two Pantoea strains isolated from extra-virgin olive oil

The olive oil is an unfavorable substrate for microbial survival and growth. Only few microorganisms use olive oil fatty acids as carbon and energy sources, and survive in the presence of olive oil anti-microbial components. In this study, we have evaluated the occurrence of microorganisms in 1-year-stored extra-virgin olive oil samples. We detected the presence of bacterial and yeast species with a recurrence of the bacterium Stenotrophomonas rhizophila and yeast Sporobolomyces roseus. We then assayed the ability of all isolates to grow in a mineral medium supplemented with a commercial extra-virgin olive oil as a sole carbon and energy source, and analyzed the utilization of olive oil fatty acids during their growth. We finally focused on two bacterial isolates belonging to the species Pantoea septica. Both these isolates produce carotenoids, and one of them synthesizes bioemulsifiers enabling the bacteria to better survive/growth in this unfavorable substrate. Analyses point to a mixture of glycolipids with glucose, galactose and xylose as carbohydrate moieties whereas the lipid domain was constituted by C6–C10 β-hydroxy carboxylic acids.Electronic supplementary materialThe online version of this article (10.1186/s13568-018-0642-z) contains supplementary material, which is available to authorized users.

“…Batch biodegradation process offers an efficient approach at shorter hydraulic retention time (HRT) for the treatment of oily wastewater (Agamuthu 1995;Nzila et al 2017 Bioaugmentation with a consortium of microorganisms is an effective approach for the removal of pollutants present in oily wastewater (Corti-Monzόn et al 2020;Ke et al 2021). Shokrollahzadeh et al (2008) treated oily wastewater in an activated sludge inoculated with a consortium of microorganisms consisting of 67 bacterial strains from Acinetobacter, Pseudomonas, Comamonas, Flavobacterium, Cytophaga, Sphingomonas, Acidovorax, and Bacillus genera and one mold species, Trichoderma sp.…”

Treatment of industrial oily wastewater by advanced technologies: a review

2021

View full text Add to dashboard Cite

Oily wastewater consists of fats, oils and greases together with a broad spectrum of dissolved organic and/or inorganic substances in suspension. It is regarded as one of the most hazardous wastewaters, causing serious environmental and health threats to the ecosystems, flora and fauna. The global increase in the discharge of oily wastewater coupled with stringent regulations for effluent discharge and incessant drive for re-use of treated wastewater necessitate the need for treatment of the wastewater. Conventional approaches employed in the past are inept for oily wastewater treatment due to low treatment efficiency and high operational costs, among others, hence the need for adoption of advanced technologies as promising alternatives to existing treatment systems for oily wastewater. Furthermore, the use of combined treatment processes is effective for the removal of hazardous pollutants present in high-strength oily wastewater. This review provides insights into advanced and emerging state-of-the-art technologies for safe and efficient treatment of industrial oily wastewater.

“…Oils and fats were examined using SM 5520 B, a partition-gravimetric method, where dissolved or emulsified oils were extracted from the water using an extracting solvent. The solvent was then evaporated, and the difference between the weight before and the weight after evaporation indicated the amount of oils and fats (34).…”

The Lachish River has suffered from recurring pollution incidents for the past decade. On October 11th, 2017, another contamination in the river was sighted, as thousands of dead fish were found floating. Samples from the river were retrieved and tested through a whole cell bioluminescent bacterial bioreporter system as well as conventional analytical methods, and the results from both methods were analyzed and compared, even though initially these two collecting events were not coordinated. The information acquired from the whole cell reporter was consistent with that obtained from conventional methods. Both approaches indicated a large concentration of microorganisms as deduced from K802NR E. coli strain reaction and coliforms count. The high water conductivity measured in collected samples were closer downstream, and attributed to the diffusion of salts from the Mediterranean Sea which affected bacterial viability as seen from the decreased reaction of E. coli strains TV1061 and DPD2794. In addition, the bacterial indicators’ kinetic patterns have shown indication for the presence of a genotoxic substance from only one of the collection sites, which was tested positive for the herbicide Metazachlor, itself known to have genotoxic effects. The correlation between both approaches, along with the biosensor’s ability to assess biological influences, suggests that the whole cell bioluminescent bacterial bioreporter bioassay as an easy, simple and efficient approach for water toxicity monitoring.
