Analysis of distribution of oxygen transfer rate in stirred bioreactors for fungus broths 1. Suspensions of P. Chrysogenum free mycelia
Environmental Engineering and Management Journal › Vol. 9 › Nr. 2 Abstract
Unlike the P. shermanii and S. cerevisiae cultures, the study on the distribution of oxygen transfer in stirred bioreactor for P. chrysogenum free mycelia broths indicated that this process is controlled mainly by the high apparent viscosity of broths, and less by the presence of fungus biomass. For this reason, the influence of fungus accumulation on the reduction of kla is attenuated compared with that obtained for bacterial or yeasts broths. The lower influence of fungus biomass i...

Validation of a knowledge-based risk model for biological foaming in anaerobic digestion simulation
Environmental Engineering and Management Journal › Vol. 9 › Nr. 2 Abstract
Anaerobic digestion (AD) is a complex biological system which can be affected by several operational problems. Among them, biological foaming is one of the most difficult to deal with. It has many effects, such as causing gas pipe clogging and probe failures, and it can affect mixing devices, etc. Since the mechanisms involved in biological foaming development are not fully understood, it is not included in standard anaerobic digestion models. For this reason, a knowledge-based risk ...
