چکیده

The alarming rate of population growth has increased the demand for food production in third world countries leading to a deep gap in demand and supply. This situation has created a demand for the formulation of innovative and alternative proteinaceous food sources. Single cell protein (SCP) production is a major step in this direction. The bacterial single-cell protein, produced by aerobic fermentation of natural gas with Methanotrophic bacteria, is a potential protein source for man and animals. Optimization of the process parameters with Taguchi design method, amino acid profile and removal of nucleic acids from SCP by heat shock treatment as a protein supplementing source are discussed in this research. Protein production in the optimum condition was 69.3 (w/w) % of biomass which its structural amino acids can be in contest with other nutrient sources. An average amount of 10g for RNA out of any 100g of cellular protein was extracted from the biomass.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
