Abstract

In parallel with the development of biotechnology, the production of organic and biochemical substances by fermentation process is one of the most current issue of our age's technology. Many chemical substances widely used in various industrial fields, such as organic solvents, antibiotics and enzymes that are produced by microorganisms in fermentation processes. Many common organic acids such as citric acid, lactic acid, fumaric acid, malic acid and salicylic acid used in food, pharmaceutical, chemical, textile, plastics, cosmetics and paper industries can be produced by fermentation. In the present study, L(+) lactic acid was produced from refectory wastes through fermentation process and fermentation process was optimized for the maximum lactic acid yield. Process variables for batch system were optimized for the production of lactic acid from pretreated macaroni-milk and rice-green pea-salad broths by L. casei culture. For the fermentation of the macaroni-milk and rice-green pea-salad broths with L. casei culture, 42.16 g/L and 41.56 g/L lactic acid were obtained with 80% and 83% conversion efficiency when medium pH was set to 6.0, temperature was held at 45°C, agitated at 160 rpm.

Özet

Biyoteknolojinin gelişimine paralel olarak fermantasyon ile organik ve biyokimyasal maddelerin üretimi çağımız teknolojisinin en güncel konuları arasında yer almaktadır. Çeşitli sanayi dallarında geniş kullanım alanları bulunan organik çözücüler, antibiyotikler, enzimler gibi pekçok kimyasal madde ve sitrik asit, laktik asit, fumarik asit, malik asit ve salisilik asit gibi besin, ilaç, kimya, tekstil, plastik, kozmetik ve kağıt endüstrilerinde kullanılan birçok organik asit de fermantasyon yolu ile üretilebilmektedir. Bu çalışmada yemekhane atıklarından fermantasyon yoluyla L(+) laktik asit üretilmiş ve üretim prosesi için en yüksek konsantrasyonda laktik asit üretimine imkan veren koşullar tespit edilmiştir. Sunulan çalışmada yemekhane atığı olarak seçilen makarna-süt ve pilav-bezelye-salata karışımından Lactobacillus casei bakterisi ile laktik asit üretiminde kesikli sistem için bazı proses değişkenleri tespit edilmiştir. L. casei kültürü ile yapılan laktik asit fermantasyon çalışmaları verilerinden, pH değeri 6.0, fermantasyon sıcaklığı 45°C, karıştırma hızı 160 rpm olduğu durumda, makarna-süt ve pilav-bezelye-salata olarak belirlenen besiyerlerinden sırasıyla 42,16 g/L ve 41,56 g/L miktarında laktik asit %80 ve %83 dönüşüm verimleri ile elde edilmiştir.
