MEGBI Planning&Control 2022

Lab contents 2022



Report for July -Sep 2022 (Achieved)

Penicillin production:

Not achieved yet

Problems: conditions not respected (optimum temperature: 26-28°c, pH control: pH meter not working, shaker for the incubator and last edit: replace milk powder by lactose).

Penicillin quantification:

Crystallization not achieved penicillin G sodium, solvent need to changed butyl acetate instead of ethyl acetate achieved.   

Ampicillin production:

Achieved, but yield is low (concentration between: 0.17-0.20). 

Ampicillin quantification:

Crystallization not achieved ampicillin sodium, solvent need to changed butyl acetate instead of ethyl acetate.  



MEGBI procurement list 2022

TODOs 2022:

    • Make sure of the buyed Penicillin G as Benzathin Penicillin G (2d, Material Costs: …)
    • Quantification of the produced Penicillin G (as Master Thesis)
    • Run the bioreactor in term to produce Penicillin G as pilot plant lab scale (as Master Thesis)
    • Production of Ampicillin from the produced penicillin G (as Master Thesis)
    • Quantification of the produced ampicillin (as Master Thesis)
    • Aspirin production Labscale (time: 2w, staff: 1MM, material costs: 50$) (planned: Feb 2020)
