Simple models for the continuous aerobic biodegradation of phenol in a packed bed reactor

Abstract

ABSTRACT

Ex situ bioremediation of Cr(VI) contaminated soil by Bacillus sp.: Batch and continuous studies

“…The model presented by Gerrard et al (2006) was used to model the bioconversion of Cr(VI) in a packed bed reactor [36]. The design equation for packed bed reactor with plug flow is given as:…”

Biodegradation of phenol by Pseudomonas putida immobilized in polyvinyl alcohol (PVA) gel

“…Under aerobic conditions, phenol may be converted by the bacterial biomass to carbon dioxide; other intermediates such as benzoate, catechol, cis-cismuconate, ␤-ketoadipate, succinate and acetate are known to be formed during the biodegradation process [12]. P. putida has been studied by many researchers in free and immobilized forms, using different types of bioreactors [2,[13][14][15][16][17][18][19][20][21][22][23].…”

A simplified model for A. Niger FS3 growth during phytase formation in solid State fermentation

“…The Monod model was also well fitted to the experimental data to determined choose of parameters (R²=0.995), and consequently, it is recommendable not to discard the hypothesis of growth limitation due to substrate limitation. Monod model was also gave the best fit to the experimental data in studies by Gerard et al (2006). It is important to detach that biologic processes are extremely complexes, and they have numberless variables interfering in the process.…”
