From Perry's Chemical Engineers' Handbook, the density of water at 28°C ρL = 0.9962652 g cm–3 and the viscosity of water at 28°C µL = 0.87 cP. The density of oxygen at 28°C and 1 atm pressure can be calculated using the ideal gas law. As molar density is the same as n/V, from Eq. (2.35): ρG = n p = V RT
Background Multi-copy gene integration into microbial genomes is a conventional tool for obtaining improved gene expression. For Penicillium chrysogenum, the fungal producer of the beta-lactam antibiotic penicillin, many production strains carry multiple copies of the penicillin biosynthesis gene cluster. This discovery led to the generally accepted view that high penicillin titers are the ...
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is flowsheet
processes, we used a BioFlo 320 bioprocess control station. We investigated the k L a capabilities of each vessel using the static gassing-out method. For each vessel, we determined the k L a at tip speeds between 0.3 and 0.7 m/s and gas flow rates between 0.01 and 0.15 vessel volumes per minute (VVM). For the different experimental conditions,
The achieved root mean square errors of cross-validation for the PLS regressions were 0.22 g L −1 for Penicillin V and 0.32 g L −1 for phenoxyacetic acid and the root mean square errors of prediction for MCR-ALS were 0.23 g L −1 for Penicillin V and 0.15 g L −1 for phenoxyacetic acid.

Flow cytometry analyses (Fig. 5f and Additional file 1: Figure S2) revealed that, for all conditions, following 7 days of expansion in the VWBR, expression of pluripotency markers OCT4 and TRA-1-60 was always above 90% and expression of early differentiation surface marker SSEA-1 was maintained at less than 10%.
Penicillin V and phenoxyacetate (Pox) were quantified by HPLC. Chromatographic separation was achieved by a Zorbax Eclipse AAA column, 4.6 × 12.5 mm, 5 μm (Agilent Technologies, California, USA) with an eluent composed of 28% acetonitrile, 0.005 M potassium dihydrogen phosphate and 0.07% phosphoric acid and a flow rate of 1.0 ml min −1 .

The issue of a patent for penicillin was a controversial problem from the beginning. Chain believed that obtaining a patent was essential. Florey and others viewed patents as unethical for such a life-saving drug. Indeed, penicillin challenged the basic notion of a patent, considering it was a natural product produced by another living ...
