Ustilago maydis, member of the Ustilaginaceae family, is a promising host for the production of several metabolites including itaconic acid. This dicarboxylate has great potential as a bio-based building block in the polymer industry, and is of special interest for pharmaceutical applications. Several itaconate overproducing Ustilago strains have been generated by metabolic and morphology engineering. This yielded stabilized unicellular morphology through fuz7 deletion, reduction of by-product formation through deletion of genes responsible for itaconate oxidation and (glyco)lipid production, and the overexpression of the regulator of the itaconate cluster ria1 and the mitochondrial tricarboxylate transporter encoded by mttA from Aspergillus terreus. In this study, itaconate production was further optimized by consolidating these different optimizations into one strain. The combined modifications resulted in itaconic acid production at theoretical maximal yield, which was achieved under biotechnologically relevant fed-batch fermentations with continuous feed.

Abstract Background Itaconic acid is a bio-derived platform chemical with uses ranging from polymer synthesis to biofuel production. The efficient conversion of cellulosic waste streams into itaconic acid could thus enable the sustainable production of a variety of substitutes for fossil oil based products. However, the realization of such a process is currently hindered by an expensive conversion of cellulose into fermentable sugars. Here, we present the stepwise development of a fully consolidated bioprocess (CBP), which is capable of directly converting recalcitrant cellulose into itaconic acid without the need for separate cellulose hydrolysis including the application of commercial cellulases. The process is based on a synthetic microbial consortium of the cellulase producer Trichoderma reesei and the itaconic acid producing yeast Ustilago maydis. A method for process monitoring was developed to estimate cellulose consumption, itaconic acid formation as well as the actual itaconic acid production yield online during co-cultivation. Results The efficiency of the process was compared to a simultaneous saccharification and fermentation setup (SSF). Because of the additional substrate consumption of T. reesei in the CBP, the itaconic acid yield was significantly lower in the CBP than in the SSF. In order to increase yield and productivity of itaconic acid in the CBP, the population dynamics was manipulated by varying the inoculation delay between T. reesei and U. maydis. Surprisingly, neither inoculation delay nor inoculation density significantly affected the population development or the CBP performance. Instead, the substrate availability was the most important parameter. U. maydis was only able to grow and to produce itaconic acid when the cellulose concentration and thus, the sugar supply rate, was high. Finally, the metabolic processes during fed-batch CBP were analyzed in depth by online respiration measurements. Thereby, substrate availability was again identified as key factor also controlling itaconic acid yield. In summary, an itaconic acid titer of 34 g/L with a total productivity of up to 0.07 g/L/h and a yield of 0.16 g/g could be reached during fed-batch cultivation. Conclusion This study demonstrates the feasibility of consortium-based CBP for itaconic acid production and also lays the fundamentals for the development and improvement of similar microbial consortia for cellulose-based organic acid production.

State Of The Environment

In Ukraine there is a tendency to increase the number of man-made emergencies, which directly affects the state of the environment and the population. Particularly dangerous situations are formed in case of disturbance of objects with high risk conditions, which include oil extraction enterprises. Observing the state of the environment and the operation of technological equipment at such enterprises, warning of the risk of emergencies that are hazardous to human health and the environment, are the basis and task of monitoring. The results of engineering and ecological analysis of the state of ecological and technogenic danger on the example of private joint-stock company «Kropyvnytskyi oil extraction plant» are presented in the work. The main probable factors of its formation at each technological stage of production are established. The sources of environmental and human hazards are technological equipment and materials. Pollutants of land, water and atmospheric air are dust of vegetable origin and meal, solvent of hexane and its vapors, carbon dioxide and washing solution - soda ash, etc. Expert evaluation of the main production operation - oil extraction was carried out in detail. The extraction process is the main production operation for both press oil and extraction oil, as well as cake and meal. The results of the study can be used to clarify the program of monitoring the sources of technogenic and environmental risk at high risk facilities, planning activities and means of improving the resilience of the enterprises of the industry, preventing emergencies and minimizing their consequences. Awareness enhances management efficiency and minimizes environmental and population risks.
