Addressing global food security is a paramount challenge that necessitates shift towards enhanced self-sufficiency. The escalating demand for animal-derived proteins, such as meat and dairy, underscores the critical role of livestock farming in meeting nutritional needs population. To sustain this, protein-rich feed, essential production, consumes considerable share agricultural resources. Concurrently, urban expansion significantly increases organic waste, undermining both economic environmental sustainability. This highlights urgent need innovative waste management solutions bolster Microbial protein (MP), produced by methane-oxidizing bacteria (MOB), presents promising solution. It offers land-independent method producing feed aquaculture, potentially alleviating pressure on lands. Despite its advantages, reliance natural gas MP production raises sustainability concerns when compared to traditional feeds like fishmeal soybean meal. Recent research focuses valorizing materials using high-protein microorganisms animal thereby addressing these concerns. Aerobic fermentation methane produce MP, utilizing methanotrophic microbes, showcases distinct advantages. These microbes biomass, containing over 75% protein, offering viable alternative conventional sources. review explores potential biowaste valorization through integration anaerobic digestion (AD) subsequent biogas. delves into mechanisms biogas from AD highlighting methane's value advancements, challenges inefficient fermenters, MOB inhibition, safety issues hinder large-scale production. Further investigation life cycle assessment (LCA) techno-economic analysis (TCA) integrated technologies enhancing establishing sustainable system.

Single cell protein (SCP, or microbial protein) is one of the emerging alternative sources to address global challenge food insecurity. Recently, SCP produced from methane has attracted substantial attention since a renewable resource attainable anaerobic digestion. However, supply methane, an insoluble gas in water, major challenges producing methane-based SCP. This work developed novel bioreactor configuration, which hollow fiber membrane was used for efficient while microorganisms were growing suspended form favourable biomass harvest. Over 312-day operation, impacts three critical parameters on production investigated, including ratio loading ammonium loading, oxygen and sludge retention time (SRT). Under condition 4 g CH

The sulfur cycle is a complex biogeochemical characterized by the high variability in oxidation states of sulfur. While essential for life processes, certain compounds, such as hydrogen sulfide, are toxic to all forms. Micro-organisms facilitate cycle, playing prominent role even extreme environments, soda lakes, acid mine drainage sites, hot springs, and other harsh habitats. activity these micro-organisms presents unique opportunities mitigating sulfur-based pollution enhancing recovery metals. This review highlights application sulfur-oxidizing -reducing environmental biotechnology through three illustrative examples. Additionally, it discusses challenges, recent trends, prospects associated with applications.

Biogas can be converted into high-value bioproducts through fermentation processes. This study proposes a conversion platform where sulfide-rich biogas is utilized as the substrate for growth of mixed culture methane- and sulfur-oxidizing bacteria production protein-rich microbial biomass. The role several process variables such biomethane vs biogas, synthetic real composition H2S concentration during performed in bubble column reactors was evaluated terms biomass growth, yield volumetric productivity, protein content amino acids profile well community evolution. Despite presence 1500 ppm equivalent or (CH4:CO2 ratio 70:30), good performances (559.9 ± 13.3–677.8 46.8 mg volatile suspended solids (VSS) per liter), (0.042 0.004–0.050 0.08 VSS CH4-equivalent chemical oxygen demand (CH4-COD)) (51.9 3.6 % − 59.2 g protein/g VSS) were achieved. increasing sulfide concentrations until 4000 tolerated by increased valuable S-amino acids, i.e., cysteine methionine (61.3 mg/g 58.3 biomass, respectively), which up to 2.50 2.57 times higher than absence sulfide, respectively.
