Abstract
The present study was carried out to evaluate of utilization some of
food wastes such as guava pomace, sugar cane bagasse and corn cobs, which
were treated by dilute acid hydrolysis to reducing sugars, and utilized as
substrate for the production carotenoid by yeast strains Rhodotorula glutinis
(isolated from some plant leaves) To select the suitable environmental
conditions and nutrient requirements, which gave the highest production from
total carotenoids.
Improving the carotenoid productivity of the wild strain by
mutagenesis treatment of the wild strain using UV radiation.
In addition, the potential application of the yeast carotenoid extract as
source of natural color and antioxidant agents were investigated in some food
products. And utilizes
The results obtained from the present study could be summarized as.
