Abstract : The purpose of biological products raw and auxiliary materials kicked the biological load is drug production environment has been contaminated by microorganisms, The paper on biological products often use the dibasic sodium phosphate, sodium dihydrogen phosphate, polyethylene glycol 4000, peptone, yeast, Polysorbate 80, sodium acetate seven raw and auxiliary materials for biological research load. Methods film filter (50mm size, aperture ∧ 0,145 m) from the collection of filtration, Red roses were used sodium agar medium potato dextrose agar medium, soybean trypsin casein agar medium for training, Statistics from the sample contained fungi, yeast fungi, 95.00 quantity. Results Polysorbate 80, PEG 4000 was not found in microbes, load very low; Peptone, yeast microorganisms were detected in more than 5,000 g, biological load is high; inorganic salts of sodium acetate, sodium dihydrogen phosphate, Na2HPO4 lower than the load, but there is pollution to the risk. Conclusion raw and auxiliary materials used in the process, they should be brought to the microbial production of environment pollution, especially peptone. Yeast Powder high bacterial content of the raw materials pollution Keywords : biological load; raw and auxiliary materials; membrane filtration method
