,Rechtliches Gebäudemanagement,uring of bacteria causes no methodological difficulties, provided that suitable culture vessels and a centrifuge of an adequate capacity are at hand. The growth, concentration and purification of phages, however, is more complex. Therefore in the following three experiments we want to demonstrate th

,Rechtliches Gebäudemanagement,Soft agar, immediately after autoclaving, is distributed in 3 ml portions into small test tubes and kept molten in a 47°C water bath. If a medium is to be supplemented with a material whose heat stability is doubtful (e.g., antibiotics), it is recommended that concentrated stock solutions of the mat

,Technisches Gebäudemanagement,All studies in quantitative biology are made with the goal of obtaining results which are fairly representative. However, in most experiments one studies only a small sample. In order to make this procedure valid, samples should be taken randomly.
