Özet:

 Animal feeding operations AFOs are significant sources of airborne pollutants, particularly ammonia NH₃, which pose considerable environmental and health risks. In response to these challenges, photobioreactor PBR systems utilizing microalgae have emerged as a promising solution. These systems can effectively absorb and metabolize pollutants such as NH₃ and carbon dioxide CO₂, thereby improving air quality while simultaneously producing valuable biomass. The present study specifically investigated the effects of elevated NH₃ concentrations on algal growth within PBRs. Ammonium chloride NH₄Cl was employed to simulate NH₃ concentrations typical of animal housing, specifically at a loading rate of 50 ppm 78 mg L¹ d¹ NH₄Cl. Over a 21-day experimental period, control tanks containing standard Bolds Basal Medium BBM were compared against those with NH₃ exposure. Results indicated that while normalized cell concentrations were highest in control tanks 1.790.09, p0.01, the dry biomass was significantly greater in tanks subjected to the 50 ppm NH₃ loading rate 1.340.02, p0.01. These findings suggest that microalgae possess a remarkable capacity to adapt to high NH₃ levels, highlighting their potential role in emission mitigation and sustainable biofuel production. The integration of PBR systems utilizing microalgae represents a viable strategy for addressing the environmental and health challenges posed by AFOs. By effectively utilizing pollutants such as NH₃, these systems not only enhance air quality but also contribute to the development of sustainable biofuels, thus supporting broader environmental sustainability goals.

 Yoğun hayvancılık faaliyetleri, amonyak NH₃ da dahil olmak üzere havayla taşınan önemli kirleticiler üreterek çevre ve sağlık riskleri oluşturmaktadır. Fotobiyoreaktör PBR sistemleri, NH₃ ve CO₂ gibi kirleticileri absorbe etmek ve metabolize etmek, hava kalitesini artırmak ve değerli biyokütle üretmek için mikroalgleri kullanan umut verici bir çözüm olarak ortaya çıkmıştır. Bu çalışma, hayvan barınaklarında tipik olarak görülen yüksek amonyak konsantrasyonlarını azaltmak için yüksek NH₃ konsantrasyonlarının PBRlerde alg büyümesi üzerindeki etkisini araştırmaktadır. Amonyum klorür NH4Cl, NH₃ yerine kullanılmış ve nitrat içermeyen BBM ortamı hayvan barınaklarında tipik olarak görülen 50 ppm 78 mg L-¹ d-¹ NH4Cl NH₃ konsantrasyonunu simüle etmiştir. Her deney 21 gün boyunca normal BBM 0,25 g L-¹ NaNO3 içeren kontrol tanklarında gerçekleştirilmiştir. Normalize edilmiş hücre konsantrasyonları NH3 içermeyen PBR tanklarında en yüksek 1.790.09, p0.01, ancak kuru biyokütle 50 ppm NH3 yükleme oranına sahip tanklarda daha yüksekti 1.340.02, p0.01. Hücre konsantrasyonları 50 ppm NH3 ile azalırken, kuru biyokütle NH3 içermeyen tanklara kıyasla artmıştır. Sonuçlar, mikroalglerin emisyonları azaltma, yetiştirme stratejilerini optimize etme ve sürdürülebilir biyoyakıt üretimini destekleme potansiyelini ortaya koymakta ve PBRlerin çevresel etkileri azaltma ve atık kaynakları geri dönüştürmedeki rolünü vurgulamaktadır.
