Production of Pigment From Yeast

Öz

Pigments are coloring substances that do not dissolve completely in the medium in which they are included. They are generally classified as natural and synthetic based on their source. In addition to advantages such as low cost and high efficiency, synthetic pigments have disadvantages such as harmful effects on health and the environment (non-biodegradability). Yeast pigments are used as an alternative to synthetic pigments with their safe, non-toxic and biodegradable properties. It is used as an alternative to other microbial pigments with a high growth rate of yeasts, easy adaptation to various cheap substrate sources and non-toxicity. By optimizing various parameters such as the amount of carbon, nitrogen and mineral substances, pH, temperature, incubation time, and agitation speed in the fermentation medium, environmentally friendly, more efficient and higher economic value pigment production can be achieved from yeast. Pigments obtained from yeast have positive effects on health such as antioxidant, antimicrobial, anticancer and antitumor, and have the potential to be used in various industries (food, medicine, cosmetics, textiles, etc.).

Mayalardan Pigment Eldesi

Öz

Pigmentler dahil edildiği ortamda tamamen çözünmeyen renklendirici maddelerdir. Genellikle kaynaklarına göre doğal ve sentetik olarak sınıflandırılırlar. Sentetik pigmentler düşük maliyet ve yüksek verimle üretilebilmeleri gibi avantajların yanı sıra sağlığa ve çevreye zararlı etkilere sahip olması gibi dezavantajlara sahiptir. Maya pigmentleri güvenli, toksik olmama ve biyolojik olarak parçalanabilme özellikleriyle sentetik pigmentlere, mayaların yüksek gelişme hızı, çeşitli ucuz substrat kaynaklarına kolay uyumu ve toksin oluşturmama özellikleriyle de diğer mikrobiyal pigmentlere alternatif olarak kullanılmaktadır. Fermantasyon ortamında karbon, azot ve mineral madde miktarı, pH, sıcaklık, inkübasyon süresi, çalkalama hızı gibi çeşitli parametrelerin optimizasyonuyla mayalardan çevreye zarar vermeyen, daha verimli ve daha yüksek ekonomik değere sahip pigment üretimi sağlanabilir. Mayalardan elde edilen pigmentler antioksidan, antimikrobiyal, antikanser ve antitümör gibi sağlık üzerine olumlu etkilere ve çeşitli endüstrilerde (gıda, ilaç, kozmetik, tekstil gb.) kullanılma potansiyeline sahiptir.
