Single cell protein production using low quality fruits of some dates

Single cell protein (SCP) is a good source of essential amino acids. This study aimed to utilize some date by-products such as fruit flesh produce single protein.  Fruit three unknown dates and varieties were used by Saccharomyces cerevisiae ATCC64712 under different condition (sugar concentrations in the extract media, temperatures pH values). The results showed that optimum production biomass (42.85 g/l) was produced from extracts media at 18% sugar, 30˚C 4.5. To reduce nucleic acids content biomass, heat shock used. effect on percentage for studied yeast strain 75.83%, maximum reduction observed pH4 60°C 30 sec with 20.88% loss its content. present provides evidence great can be variable fermentations. Additionally, has high level lysine, methionine threonine. been proved replacement other expensive sources like fish soybean meals. Therefore, conclusion made easily replace traditional (plant animal) human, animal well diets without any detrimental effect.
