They used to store algae in either in liquid in culture vessels, or on agar plates in petri dishes. Either way, both the vessel openings and the edges of the petri dishes were taped up with Parafilm which is breathable enough to allow for gas exchange but
should keep unwanted spores out. I can’t see why the same technique shouldn’t work well for mould cultures so I would give it a go.

<p class="MsoNormal"><span style="color:#1F497D;mso-fareast-language:EN-US">Ironically, we had to check the cultures on a weekly basis for mould infection and, if necessary, pick out individual algal cells to start new, clean cultures.

<p class="MsoNormal" style="margin-left:36.0pt"><span lang="EN-US">Can anyone recommend a good method for sealing plastic petri dishes containing mold cultures for long term collections storage for our botany department’s herbarium? Ideally, the method we are
looking for would be secure but reversible, in case we need to directly access the samples in future. Some ideas we have considered include using strips of Parafilm or white plumbers’ “tape” around the edges of the petri dishes. <o:p></o:p></span></p>
