    Bioethanol Production From C1 Gases Using Alternative Media by Syngas Fermentation
    (Inderscience Enterprises Ltd, 2022) Gungormusler, Mine; Azbar, Nuri; Keskin, Tugba
    The main aim of the present study was to evaluate the effects of the presence or absence of trace elements and yeast extract on growth and ethanol production by Clostridium ragsdalei grown on C1 gas dominated syngas (60% CO, 10% CO2, 10% CH4, 10% H-2, 10% N-2). Comparison of whey powder and glucose syrup as low-cost substitutes helped develop a more cost-effective medium formulation to produce ethanol from syngas with significantly higher yields, achieving up to a 3.8-fold improvement with co-utilisation of syngas and glucose syrup. In addition, the results provided further insights into medium manipulation and possible modifications to decrease total costs for increased ethanol production by solventogenic acetogens via syngas fermentation by achieving a 15.6% reduction in the cost of fermentation medium.

    An Investigation on the Optimized Production of a Microalgae-Based Biopolymer Using a Novel Media Composition for Chlorella Vulgaris
    (İzmir Ekonomi Üniversitesi, 2023) Al-hammadi, Mohammed Saad Abdullah; Güngörmüşler, Mine
    Üre ile ticari NPK gübresi içeren yeni bir kültür ortamı başarıyla yapıldı ve Chlorella vulgaris için optimize edildi ve mikroalg gelişimi için iyi bir potansiyel gösterdi ve elde edilen biyokütlenin maksimum ağırlığı 280 mg/L idi. Ayrıca, elde edilen biyokütle, 50 ml kültür ortamı için %92,9 ∓ 1,322 hasat verimliliğine sahip sentezlenmiş manyetik parçacıklar kullanılarak santrifüjleme ve modifiye edilmiş bir yöntemle başarılı bir şekilde toplandı ve daha sonra geri dönüştürülerek biyoplastik üretiminde kullanıldı. PLA tozu Chlorella vulgaris biyokütlesi ile solvent-döküm yönteminde karıştırılmış ve ilk kez 105°C'de PLA ile Chlorella vulgaris biyokütlesi için iki aşamalı tavlama işlemi uygulanmış ve tavlama işlemi yapılmayan bir yöntemle kıyaslanmıştır. Sonuçlar, çekme dayanımının iyileştiğini ve maksimum ortalamanın 15.646 ±1.631 MPa olduğunu gösterdi ve bu, bildiğimiz kadarıyla, solvent döküm yönteminde PLA ile birlikte Chlorella vulgaris kullanılarak elde edilen en yüksek dayanımdır. Ayrıca deniz suyunda biyolojik bozunma gözlenmiş ve üretilen polimer deniz suyunda önemli ölçüde bozunmuştur.

    Optimization of Biohydrogen Production Yields With Locally Isolated Thermophilic Bacteria From Hot Springs
    (International Association for Hydrogen Energy, IAHE, 2022) Akaçin İ.; Ersoy Ş.; Gündoğdu T.K.; Güngörmüşler M.; Akaçin, İlayda; Gündoğdu, Tuğba Keskin; Güngörmüşler, Mine; Ersoy, Şeymanur
    Hydrogen, a carbon-free clean fuel and a strong alternative to conventional fossil energy sources, has many production strategies including biological routes, acknowledged as sustainable and environmentally friendly. The hydrogen yields acquired by those routes with either pure or mixed cultures are predominantly dependent on the environmental factors. Accordingly, in the literature, statistical experimental designs were proven to be useful to understand the effects of independent parameters including macro and micro nutrients, organic or inorganic substrates, pH and temperature. Within this scope, the aim of this study was to optimize the bio-H2 yields using the Box-Behnken design (BBD) with 3 different independent parameters (temperature(oC), pH and inorganic substrate (CO volume (mL)) with a comparative approach using both mixed and pure thermophilic cultures isolated from Izmir hot springs. The maximum H2 yields were reported as 0.13 mmol H2/mmol CO for mixed cultures at pH 7, 60oC and 15 mL CO addition whereas the pure culture reached 2.5 fold higher yields by 0.46 mmol H2/mmol CO. The results demonstrated the effectiveness of the utilization of the statistical design of experiments to improve the bioproduction yields via local thermophilic isolates. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.

    Production of Value-Added Bioproducts Using a Modified Continuous Biofilm Reactor by Citrobacter Freundii Dsm 15979
    (2021-03-31) Güngörmüşler, Mine
    The present paper reports the results of Citrobacter freundii, strain DSM 15979, that was tested for its ability to produce value added chemicals from biodiesel derived glycerol in a mesophilic fluidized bed biofilm reactor operating under continuous conditions at a specified hydraulic retention time (HRT) at 30°C. Elevating feed concentrations (10 to 144 g/L) were tested in order to understand their effects on simultaneous production of value added products with immobilized whole cells. Gin was found to be a significant independent variable for the productions of 1,3-PDO, 2,3-BD, ethanol, acetic, succinic and lactic acids under different organic loading rates (OLR). The major metabolite in the metabolic pathway was found to be 1,3-PDO followed by 2,3-BD reaching the maximum values as 26.1 and 18.8 g/L under the conditions of 92 g/L crude glycerol and 8 h, which is represents an OLR of 11.5 g/L.h, suggesting the formation of biofilms favor the utilization of high substrate concentration to enhance the mixed fermentation.

    Hydrogen Production by Immobilized Cells of Clostridium Intestinale Strain Urnw Using Alginate Beads
    (Springer, 2021-01-23) Gungormusler, Mine; Tamayol, Ali; Levin, David B.
    Biological hydrogen (H-2) is a promising candidate for production of renewable hydrogen. Using entrapped cells rather than conventional suspended cell cultures for the production of H-2 offers several advantages, such as improved production yields related to higher cell density, and enhanced resistance to substrate and end-product inhibition. In this study, H-2 production by a novel isolate of Clostridium intestinale (strain URNW) was evaluated using cells entrapped within 2% calcium-alginate beads under strictly anaerobic conditions. Both immobilized cells and suspended cultures were studied in sequential batch-mode anaerobic fermentation over 192 h. The production of H-2 in the headspace was examined for four different initial cellobiose concentrations (5, 10, 20, and 40 mM). Although a lag period for initiation of the fermentation process was observed for bacteria entrapped within hydrogel beads, the immobilized cells achieved both higher volumetric production rates (mmol H-2/(L culture h)) and molar yields (mol H-2/mol glucose equivalent) of H-2 compared with suspended cultures. In the current study, the maximum cellobiose consumption rate of 0.40 mM/h, corresponding to 133.3 mg/(L h), was achieved after 72 h of fermentation by immobilized cells, generating a high hydrogen yield of 3.57 mol H-2/mol cellobiose, whereas suspended cultures only yielded 1.77 mol H-2/mol cellobiose. The results suggest that cells remain viable within the hydrogels and proliferated with a slow rate over the course of fermentation. The stable productivity of immobilized cells over 8 days with four changes of medium depicted that the immobilized cells of the isolated strain can successfully yield higher hydrogen and lower soluble metabolites than suspended cells suggesting a feasible process for future applications for bioH(2) production.

    Bioprocesses for Resource Recovery From Waste Gases: Current Trends and Industrial Applications
    (Pergamon-Elsevier Science Ltd, 2022-03) Khanongnuch, Ramita; Abubackar, Harris Nalakath; Keskin, Tugba; Gungormusler, Mine; Duman, Gozde; Aggarwal, Ayushi; Behera, Shisir Kumar; Rene, Eldon R.
    Air pollution is a topic of important global concern because it has contributed significantly to an increase in the earth's global warming potential and contributed to severe health and environmental impacts. In this review, the different bioreactor configurations commonly used for waste gas treatment, namely the biofilters, the bio-trickling filters and the bioscrubbers, and their industrial applications were compared in terms of the type of inoculum, the packing material/media, removal efficiency and elimination capacity. Typically, biofilters are operated under the following range of operating conditions: gas residence time = 15-60 s; gas flow rate = 50-300,000 m(3) h(-1); temperature = 15-30 ?degrees C; pH = 6.0-7.5; filter area = 100-3000 m(2); relative humidity > 95.0%; and removal efficiencies > 75.0% depending on the waste gas composition and concentration. The biotechnological approaches for resource recovery, i.e., the conversion of C1 gaseous compounds (CO, CO2 and CH4) to liquified value-added products or biofuels have been discussed. From this review, it was evident that the performances of different aerobic, anoxic and/or anaerobic lab, pilot and full-scale bioreactors for waste gas treatment and resource recovery depend on the composition, the individual concentration of pollutants present in the waste gas and the gas flow rate. Although most of the research on product recovery from waste gas is rather limited to lab/pilot-scale studies, there are some key commercialized technologies that have proven to be economical at the full-scale. Thus, this review, comprehensively presents a complete overview of the current trends and limitations of conventional waste gas treatment systems, the benefits of novel bioreactor configura-tions and their potential to be applied for resource recovery from waste gases.

    From Fossil Fuels to Green Hydrogen: a Pathway to Environmental Sustainability
    (Springer Science+Business Media, 2025) Kerimov, M.; Gungormusler, M.
    This chapter examines the role of green hydrogen and renewable resources in addressing the global climate crisis and achieving sustainability. It highlights the European Union’s goal to become the first net-zero carbon continent by 2050, emphasizing the importance of hydrogen as a clean energy carrier, which produces only water vapor when utilized. Current hydrogen production methods, predominantly from fossil fuels, result in significant CO[[inf]]2[[/inf]] emissions. Up to 35% of global hydrogen production is used in oil refineries, where it is crucial for hydrocracking and hydrodesulfurization processes. Despite the high environmental cost, hydrogen demand in refineries is increasing due to stricter environmental regulations. As discussed in this chapter, the integration of green hydrogen into oil refinery operations, alongside existing hydrogen generation plants, presents a viable pathway to decarbonization. In this context, details of various hydrogen production technologies, conventional fossil fuel based, and renewable-based methods such as wind and solar power driven electrolysis are reported together with the cost and environmental impacts of these technologies, suggesting that green hydrogen, produced using renewable energy, is the most sustainable option. Several case studies and projects demonstrated in this chapter reveal the potential for green hydrogen to significantly reduce emissions in the refining sector, highlighting the need for global cooperation and investment in sustainable energy solutions. © 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

    Biohydrogen Production by Biological Water-Gas Shift Reaction and Bioelectrochemical Systems
    (Elsevier, 2023) Keskin, T.; Gungormusler, M.; Bayar, B.; Abubackar, H.N.
    Numerous strategies have been suggested to address the issue of global warming, which should be prioritized. Due to the availability of effective outcomes via well-established biotechnological applications, current developments have shown the benefits and superiority of nontraditional techniques for more sustainable bioprocessing. Several mesophilic and thermophilic bacteria have reported a distinct fermentation route using C1 gases (e.g. CO and CO2) frequently found in waste gas streams or syngas to generate bio commodities such as acetic acid, ethanol, butanol, 2,3-Butanediol, and hydrogen. This chapter discusses the aforementioned unconventional technologies, which include hydrogen generation technologies such as biological water-gas shift process and microbial electrolysis. Additional details on these technologies, including the effect of microbial community selection on metabolic pathways, the role of bioreactor design in enhancing liquid-gas mass transfer, process parameters, direct and mediated electron transfer mechanisms, and the characteristics of membranes that contribute to improved conductivity and stability under dynamic process conditions. Future prospects include the adaption of different process parameters and materials, such as biochar incorporation into fermentation, and the integration of technologies into bioelectrochemical systems in order to develop a more sustainable method of hydrogen generation. © 2023 Elsevier Ltd.
