Special Issue Information

Dear Colleagues,

In the present era of transformation, there is a directive focus on progressive and forward-oriented industrial and basic research, particularly in the fields of biotechnology and industrial bioprocesses. Microorganisms are poised to play a crucial role in this transition, serving as key drivers of technological advancements. Their genomes hold the potential and necessary information for the development of sustainable biotechnology on a global scale. Microbial biotechnology involves the utilization of the capabilities of microorganisms to develop innovative solutions for industrial applications. It involves the use of microorganisms, including bacteria, fungi, and algae, to produce valuable products or carry out specific processes that benefit various industries. The field of microbial biotechnology continues to evolve and innovate, driven by advances in genetic engineering, synthetic biology, and high-throughput screening technologies. These advancements enable scientists to engineer microorganisms with tailored properties and develop new applications in diverse industries.

The use of microalgae as a raw material for biogas production is promising. Macroalgae were mixed with cattle manure, wheat straw, and an inoculant from sewage sludge. Mixing macroalgae with co-substrates increased biogas and methane yield. The research was carried out using a three-stage bioreactor. During biogas production, the dynamics of the composition of the microbiota in the anaerobic chamber of the bioreactor was evaluated. The microbiota composition at different organic load rates (OLRs) of the bioreactor was evaluated. This study also demonstrated that in a three-stage bioreactor, a higher yield of methane in biogas was obtained compared to a single-stage bioreactor. It was found that the most active functional pathway of methane biosynthesis is PWY-6969, which proceeds via the TCA cycle V (2-oxoglutarate synthase). Microbiota composition and methane yield depended on added volatile solids (VSadded). During the research, it was found that after reducing the ORL from 2.44 to 1.09 kg VS/d, the methane yield increased from 175.2 L CH4/kg VSadded to 323.5 L CH4/kg VSadded. Full article
