ARTICLE FEED & ADDITIVE MAGAZINE July 2022 65 CONCLUSION In conclusion, SCP shows very attractive features as a nutrient supplement for animals. It basically comprises of protein, carbohydrate, fats, water and elements like phosphorous and potassium and essential amino acids. SCP has various benefits over animal and plant proteins in that its requirement for growth are neither seasonal nor climatic dependent therefore it can be produced all-round the year. SCP has high protein content with wide amino acid spectrum, low fat content and higher protein carbohydrate ratio than forages. It can be grown on waste and is therefore environment friendly. Thus, the use of SCP as an alternative nutrient supplement can solve the problem of food scarcity of rapidly growing population especially in a developing country like India. However, despite of all these benefits SCP production has gained less importance because of lack of acceptability of SCP as a nutrient supplement among people. Moreover, high nucleic acid content, presence of non-digestible cell wall, unacceptable colours and flavours and a high risk of contamination and cell recovery further restrict their use as a global food. Therefore, efforts should be made to find alternative substrates and methods which can minimize the pitfalls of the substrates and methods currently in use for the production of SCP and thus lead to acceptance of this valuable nutrient supplement on a global basis.
