Growth of Fusarium solani and Cladosporium halotolerans on agar: modeling and inhibition by a nonthermal plasma.

Aim: The primary objective of the study was to assess the applicability of a growth model initially developed for Aspergillus brasiliensis on solid surfaces to other micromycetes, specifically Fusarium and Cladosporium. Additionally, the research identifies conditions for complete growth inhibition of these micromycetes using two distinct sources of a nonthermal plasma (NTP).

Methods And Results: The growth model incorporates two critical parameters: growth rate and growth delay, which effectively describe the growth dynamics and the impact of NTP treatments.

Predictive modeling of molds effective elimination by external inactivation sources.

Presented paper deals with a novel application of the (nonlinear) logistic equation to model an elimination of microscopic filaments types of fungi-molds from affected materials via different external inactivation techniques. It is shown that if the inactivation rate of the external source is greater than the maximum natural growth rate of mycelium, the mold colony becomes destroyed after a finite time. Otherwise, the mycelium may survive the external attack only at a sufficiently large initial concentration of the inoculum.

Modeling the growth of Aspergillus brasiliensis affected by a nonthermal plasma.

Aim: The main objective of the study was to develop and validate a model for the growth of Aspergillus brasiliensis on surfaces, specifically on agar culture medium. An additional aim was to determine conditions for complete growth inhibition of this micromycete using two different nonthermal plasma (NTP) sources.

Methods And Results: The developed model uses two key parameters, namely the growth rate and growth delay, which depend on the cultivation temperature and the amount of inoculum.
