PRoduct formation Terms Links

LCI, where the system is quantified in a strict format of linked processes. Each process is described in terms of the physical inputs and outputs, both economic (raw materials, materials, products) and environmental (extractions from and emissions to the environment). Out of the total, an ecological profile is compiled listing and adding up all extractions and emissions of the system. An important methodological issue is allocation how to deal with multi-output processes This issue is especially important when dealing with waste management processes and will be dealt with below. 

Fig. 1. Batch growth and antibody production of Nicotiana tabacum (BY-1) cells in terms of pg 1 1 protein, wet cell concentrations, and dry cell concentrations. Dashed vertical lines represent the boundaries between lag, exponential, and stationary growth phases. The 4-day offset between peak concentrations for biomass and protein product indicates that growth and product formation are not directly linked...
