Single Cell Proteins for Human and Animal Nutrition

Öz

Protein is the highest costed nutrients in human food and animal feeds. Protein production is required

labour intensified and highly costed process. In under developed countries, unbalanced and malnutrition problems

are common, because of higher population growth. Especially, in animal originated, higher biologic valued protein

production is getting expensive because of exces natural sources using (water, manure, feed etc.) Monogastric

animals (pig, fish, poultry and pet animals) and humans are dependent on essential amino acids. These limited

amino acids are abundant in animal proteins. For a long time, reserchers are seeking alternative protein sources

for food and feed. Some microorganisms just like bacteria, yeast, algae and fungi can use some agriculturel and

industrial wastes as row materials for good quality single cell protein production.

Tek Hücre Proteinlerinin İnsan ve Hayvan Beslemede Kullanımı

Öz

İnsan ve hayvan beslemede protein, günlük hayatta ihtiyaç duyulan en önemli besin maddelerinden

birisidir. Protein üretimi hem emek yoğun ve hem de maliyeti yüksek bir işlemdir. Ekonomisi nispeten zayıf olan

gelişmekte olan ülkelerde yetersiz ve dengesiz beslenmeye bağlı sağlık problemleri, hızla artan nüfusla birlikte

daha da şiddetlenmektedir. Özellikle biyolojik değeri yüksek olan hayvansal protein üretiminde doğal kaynakların

(su, gübre, yem vb.) aşırı tüketimine ilave olarak, üretim maliyeti de yüksektir. İnsan ve tek mideli hayvanlar

(kanatlı kümes hayvanları, domuz, pet hayvanları, etçil kürk hayvanları ve balıklar) esansiyel amino asitleri

bakımından hayvansal proteinlere bağımlıdırlar. Hayvansal kaynaklara yakın düzeyde protein içeren alternatif

protein kaynaklarının gıda ve yemlerde kullanımıyla ilgili çalışmalar uzun süreden beri yapılmaktadır. Bakteri,

maya, su yosunu ve mantarlar gibi mikrobiyel canlılar, tarımsal ve endüstriyel atıkları karbon kaynağı olarak

kullanarak oldukça kaliteli proteine dönüştürebilmektedirler.
