This problem is exacerbated by the growing demand for agricultural products. To address these global challenges and promote food and biological security, a new form of agriculture is needed that aligns with the principles of sustainable development and the circular economy. This entails developing the biotechnology market and maximizing the use of renewable and eco-friendly resources, including organic fertilizers and biofertilizers. Phototrophic microorganisms capable of oxygenic photosynthesis and assimilation of molecular nitrogen play a crucial role in soil microbiota, interacting with diverse microflora. This suggests the potential for creating artificial consortia based on them. Microbial consortia offer advantages over individual organisms as they can perform complex functions and adapt to variable conditions, making them a frontier in synthetic biology. Multifunctional consortia overcome the limitations of monocultures and produce biological products with a wide range of enzymatic activities. Biofertilizers based on such consortia present a viable alternative to chemical fertilizers, addressing the issues associated with their usage. The described capabilities of phototrophic and heterotrophic microbial consortia enable effective and environmentally safe restoration and preservation of soil properties, fertility of disturbed lands, and promotion of plant growth. Hence, the utilization of algo-cyano-bacterial consortia biomass can serve as a sustainable and practical substitute for chemical fertilizers, pesticides, and growth promoters. Furthermore, employing these bio-based organisms is a significant stride towards enhancing agricultural productivity, which is an essential requirement to meet the escalating food demands of the growing global population. Utilizing domestic and livestock wastewater, as well as CO2 flue gases, for cultivating this consortium not only helps reduce agricultural waste but also enables the creation of a novel bioproduct within a closed production cycle. © 2023 Elsevier B.V., All rights reserved.Publication Metadata only Biotechnological production of hydrogen: Design features of photobioreactors and improvement of conditions for cultivating cyanobacteria(Elsevier Ltd, 2024) Kossalbayev, Bekzhan D.; Yilmaz, Girayhan; Sadvakasova, Asemgul K.; Zayadan, Bolatkhan K.; Belkozhayev, Ayaz; Kamshybayeva, Gulzhanay K.; Sainova, Gaukhar Askerovna; Bozieva, Ayshat M.; Alharby, Hesham Fasial; Tomo, Tatsuya; Kossalbayev, Bekzhan D., Department of Chemical and Biochemical Engineering, Satbayev University, Almaty, Kazakhstan, Faculty of Biology and Biotechnology, Al Farabi Kazakh National University, Almaty, Kazakhstan; Yilmaz, Girayhan, Faculty of Engineering and Natural Sciences, Bahçeşehir Üniversitesi, Istanbul, Turkey; Sadvakasova, Asemgul K., Faculty of Biology and Biotechnology, Al Farabi Kazakh National University, Almaty, Kazakhstan; Zayadan, Bolatkhan K., Faculty of Biology and Biotechnology, Al Farabi Kazakh National University, Almaty, Kazakhstan; Belkozhayev, Ayaz, Department of Chemical and Biochemical Engineering, Satbayev University, Almaty, Kazakhstan, Faculty of Biology and Biotechnology, Al Farabi Kazakh National University, Almaty, Kazakhstan, M.

Specifically, the study of biophotolysis by cyanobacteria has received great attention to produce H2, and promising research approaches have been established. To date, numerous photobioreactors (PBRs) have been built to collect cyanobacterial biomass and generate bioenergy. Additionally, different PBR parameters were adjusted to increase the product yield. PBR development holds great potential not only for cell biomass but also for biological H2 production. This review aimed to examine the mechanisms involved in H2 production by cyanobacteria, explore the factors influencing the process, and describe five distinct PBRs known for their high H2 production. This article examines the pros and cons of the most efficient PBRs for H2 production and offers insights into strategies for increasing their productivity. © 2023 Elsevier B.V., All rights reserved.Publication Metadata only Progress and innovation in key technologies for converting biomass to hydrogen(Elsevier Ltd, 2025) Kamshybayeva, Gulzhanay K.; Sadvakasova, Asemgul K.; Belkozhayev, Ayaz; Kossalbayev, Bekzhan D.; Bauenova, Meruyert O.; Zharmukhamedov, Sergei K.; Hou, Harvey J.M.; Allakhverdiev, Suleyman I.; Kamshybayeva, Gulzhanay K., Faculty of Biology and Biotechnology, Al Farabi Kazakh National University, Almaty, Kazakhstan; Sadvakasova, Asemgul K., Faculty of Biology and Biotechnology, Al Farabi Kazakh National University, Almaty, Kazakhstan; Belkozhayev, Ayaz, Department of Chemical and Biochemical Engineering, Satbayev University, Almaty, Kazakhstan; Kossalbayev, Bekzhan D., Department of Chemical and Biochemical Engineering, Satbayev University, Almaty, Kazakhstan, Ecology Research Institute, Khoja Akhmet Yassawi International Kazakh-Turkish University, Turkistan, Kazakhstan, Tianjin Institute of Industrial Biotechnology, Tianjin, China; Bauenova, Meruyert O., Faculty of Biology and Biotechnology, Al Farabi Kazakh National University, Almaty, Kazakhstan; Zharmukhamedov, Sergei K., Institute of Fundamental Problems of Biology of the Russian Academy of Sciences, Pushchino, Russian Federation; Hou, Harvey J.M., Department of Physical and Forensic Sciences, Alabama State University, Montgomery, United States; Allakhverdiev, Suleyman I., Institute of Fundamental Problems of Biology of the Russian Academy of Sciences, Pushchino, Russian Federation, Controlled Photobiosynthesis Laboratory, Timiryazev Institute of Plant Physiology, Russian Academy of Sciences, Moscow, Russian Federation, Faculty of Engineering and Natural Sciences, Bahçeşehir Üniversitesi, Istanbul, TurkeyThe growing demand for clean energy has spotlighted biomass as a promising resource for sustainable hydrogen production, providing a carbon-neutral alternative to traditional fossil fuels. This review examines the latest advancements in converting biomass to hydrogen, focusing on thermochemical methods like gasification and pyrolysis, catalyst development, and biotechnological approaches such as dark fermentation and biophotolysis. While these methods offer substantial environmental benefits, including waste reduction and renewable energy generation, challenges persist in optimizing feedstock diversity, enhancing catalyst stability, and achieving cost-effective scalability.

However, significant challenges such as thermodynamic inefficiencies, high raw material costs, low hydrogen molar yields, and difficulties in using lignocellulosic feedstocks hinder its large-scale implementation. Conventional methods have not been able to effectively address these issues, which makes modern approaches, such as in silico strategies, essential. This review explores the role of computational models like genome-scale metabolic modeling, synthetic biology, and metabolic pathway reconstruction in overcoming these barriers. By utilizing vast genomic databases and advanced computational tools, researchers can optimize microbial systems, improve hydrogen yields, and design more efficient biohydrogen production processes. These in silico methods provide a pathway to enhance the efficiency of biomass processing and enable the development of scalable and sustainable hydrogen production technologies.
