Süzme Yoğurt Altı Suyunun Arthrospira platensis ve Haematococcus pluvialis İçin Üretim Ortamı Besin Maddesi Olarak Değerlendirilmesi

Öz

Bu çalışma, süzme yoğurt atık suyunun (strained yogurt wastewater, SYW), Arthrospira platensis ve Haematococcus pluvialis mikroalglerinin miksotrofik ve heterotrofik koşullarda yetiştirilmesi için besin kaynağı olarak kullanımını araştırmaktadır. Süzme yoğurt üretiminin bir yan ürünü olan SYW, organik karbon ve protein açısından zengindir. A. platensis Zarrouk ortamında (pH 9,0; 30°C), H. pluvialis Basal Bold Medium (pH 7,0; 28°C) ortamında büyütülmüştür. Miksotrofik ve heterotrofik denemeler, büyüme ortamına farklı konsantrasyonlarda SYW (%1, 10 ve 30, v/v) eklenmesi ile gerçekleştirilmiştir. A. platensis, H. pluvialis’e kıyasla daha yüksek lipid, protein ve karbohidrat üretimi sergilemiştir. Miksotrofik koşullarda A. platensis, H. pluvialis'e göre 2 kat daha fazla lipid üretimi ile en yüksek verime ulaşmıştır. Bir sonraki aşamada, magnezyum, kalsiyum ve sodyum metallerinin bu iki mikroalg türünün lipid üretimine etkisi incelenmiştir. H. pluvialis, en yüksek lipid üretimini (2,68 mg lipid g-1 biyokütle) magnezyum içermeyen heterotrofik ortamda elde etmiştir. Buna karşılık, A. platensis en yüksek lipid üretimini (5,31 mg lipid g-1 biyokütle), büyüme ortamında magnezyumun normal konsantrasyonunun üç katına çıkarıldığı koşullarda göstermiştir. Her iki mikroalgden elde edilen lipidlerin yağ asidi profilleri belirlenmiş ve toplam yağ asidi içeriğinde yüksek oranda doymamış yağ asitleri bulunduğu ortaya konmuştur. Bu araştırma, mikroalg kültivasyonu için ilk defa kullanılmış olan SYW’nin sürdürülebilir bir besin kaynağı olma potansiyelini ortaya koymakta; mikroalg üretiminde ekonomik ve çevresel avantajlar sağlarken, aynı zamanda atık su arıtımı ve alg patlamalarının kontrolüne katkıda bulunmaktadır.

Valorization of Strained Yogurt Wastewater as Production Medium Nutrient for Arthrospira platensis and Haematococcus pluvialis

Abstract

The study investigates the utilization of strained yogurt wastewater (SYW) as a nutrient source for cultivating Arthrospira platensis and Haematococcus pluvialis in mixotrophic and heterotrophic conditions. SYW, a by-product of strained yogurt production, is rich in organic carbon and proteins. A. platensis was grown in Zarrouk medium (pH 9.0, 30°C) and H. pluvialis in Basal Bold Medium (pH 7.0, 28°C). Mixotrophic and heterotrophic experiments were carried out by adding different concentrations of SYW (1, 10 and 30%, v/v) to the growth medium. A. platensis exhibiting superior lipid, protein, and carbohydrate production compared to H. pluvialis. Optimal lipid production was achieved in A. platensis with a 2-fold increase over H. pluvialis in mixotrophic conditions. In the next stage, the effect of magnesium, calcium and sodium metals on the lipid production of these two microalgae was examined. H. pluvialis achieved its highest lipid (2.68 mg lipid g-1 biomass) production in a non-magnesium heterotrophic medium. In contrast, A. platensis's highest lipid production (5.31 mg lipid g-1 biomass) was achieved in a medium where magnesium was present at three times the concentration of the normal growth medium. The fatty acid profiles of lipids obtained by both microalgae have been determined, revealing a high proportion of unsaturation in the total fatty acid content. This research demonstrates the potential of SYW, which has been used for the first time for microalgae cultivation, as a sustainable food source; it provides economic and environmental advantages in microalgae production, while also contributing to wastewater treatment and algal bloom control.
