Abstract:
Statement of the Problem: Due to increased productivities and cultivation in marginal lands, microalgae have great potential as feedstock for biofuels alternative to plant crops. However, the current cost of producing biofuels from microalgae biomass is still high to envision massive and profitable commercialization in the near future. It is presumed that obtaining other higher-value byproducts in biorefineries would increase the profitability. Among other aspects, access to renewables as well as recycling of nutrients as substitutes for conventional fertilizers would be mandatory.
Methodology & Theoretical Orientation: We have been proposing alternative multispecies microbial cells-factories for the production of biofuels. Basically, the concept proposes the integration of operations that are exceptionally well performed by single microorganisms (whether naturally occurring or after genetic optimization) into multispecies systems than can execute more complex tasks and/or outperform any single species. We attempt to increase the use of N2 from the air as a sole source of N-fertilizer for microalgae.
Findings: We used a N2-fixing cyanobacterium that produces N-rich biomass that could be efficiently converted into biomass of a variety of microalgae. When using oleaginous strains, on-farm oil-production potential yields by ePBR simulations were up to 20-fold higher than those reported for soy oil. On the other hand, when we used microalgae accumulating carbohydrates (60-70% w/w), after a mild acid treatment for biomass hydrolysis and saccharification, bioethanol was produced at nearly 90% of its theoretical yield by fermentation with yeasts. The system also produced protein-rich biomass fractions as potential feed supplement and allowed some recycling of nutrients.
Conclusion & Significance: We have provided strong proof-of-principle suggesting potential for the economic and environmentally sustainable production of biofuels in multispecies biorefineries. Both on-farm demonstration and detailed modeling of environmental performance are required to take these ideas to a next step.

Title: Microbial contamination during storage time of diesel, biodiesel and blends (Bx): Detection, monitoring and control
Time : 11:30-11:55

Biography:
Abstract:
Statement of the Problem: Microbial contamination in fuels has been reported since 1895 and it is considered one of the main problems related to the maintenance of stored fuels’ quality. The impact of this contamination in the system depends mainly on the fuel grade, storage time and housekeeping schedules. Among the fuels, the diesel fuel formulation has changed a lot over time, mainly by the reduction of sulfur and addition of biodiesel. The purpose of this study is to describe the steps of detection, monitoring and control to avoid the installation of deteriogenic process during storage time by microbial contamination.
Methodology & Theoretical Orientation: Many studies were conducted to determine the microbial population (composition and growth capabilities) in diesel, blends Bx and biodiesel in lab conditions simulating the storage conditions. Biomass produced at interface oil-water in microcosms is a good indication of deteriogenic process in course, acidic conditions from the water phase; infrared and chromatographic analysis results to oily phase as well.
Findings: Our results have demonstrated that diesel/biodiesel blends are more susceptible to biodegradation and biomass formation during storage. The microbial composition was characterized and monitored by culture and non-culture methods (Illumina high throughput sequencing) and more than 800 genera were identified including Archea. We showed that fuel degradation, as evaluated by HATR-FTIR, was related to interfacial biofilm formation. After 60 days storage, the system treated with a multifunctional biocide package yielded more interfacial biomass, indicating that sub-effective doses may lead to increased microbial growth.
Conclusion & Significance: The determination of the level of microbial contamination is crucial to understand the vulnerability of fuel storage systems. Our results has revealed that microbial contamination is very diverse and that the use of biocide affects microbial community structure in the fuel but that some microorganisms are resistant to the biocide.
