“…All the values predicted in the non-linear adjustments produced high linear correlation coefficients among experimental and expected data (r > 0.90). These findings were in agreement with previous outcomes and are considered a response to the stress of experimental conditions (Guerra et al, 2007), culture media formulated with fish peptones and the aerobic conditions combined with a low glucose concentration (Sedewitz et al, 1984).…”

“…Higher yields of metabolite production in relation to glucose consumption were obtained using batch cultivations. This response of decreasing yields of metabolite production by LAB to the stress conditions of pH re-neutralinisation has been reported previously (Guerra et al, 2005(Guerra et al, , 2007Vázquez et al, 2005). These authors have showed for different LAB and culture media that repeated re-neutralinisations led to lower yield in the production of metabolites as ethanol, lactic and acetic acids per glucose consumed.…”

a b s t r a c tThe goal of the present work was to study the efficacy of several lactic acid bacteria (LAB) as bio-silage inoculants of swordfish, ray and shark viscera by-products. A sterilised medium was initially used as a model system for assessing the potential of these microorganisms in batch and fed-batch cultures with re-neutralisation. In all cases, batch cultivations without re-neutralisation led to the highest production and yields of the main metabolites of LAB fermentation (lactic and acetic acids). The dynamics of these metabolites followed a conversion pattern from lactic to acetic acid with a final joint concentration over 16 g/L and final pH lower than 4.5. Both productions were modelled by means of logistic modified equations. In addition, the capability of LAB to ferment the fish visceral wastes was always high and easily reproducible. Finally, the results obtained for non-sterilised fermentations with Lactobacillus casei CECT 4043 were similar to those obtained for sterilised media, and a stable material was obtained after 72 h of culture.

“…9a and c, it is evident that production of lactic acid is both associated with growth and non-growth type because its concentration increases monotonically even after the cessation of exponential growth phase. Both the findings are comparable to the results of previous [12]. The rates of glucose and protein consumptions are 0.46/gL/h and 0.24/gL/h 1 , respectively.…”

Objectives: The aim of the study was to determine the growth kinetics of Pediococcus acidilactici using a mathematical model for large scale pediocin production.Methods: Growth kinetics of P. acidilactici has been studied for pediocin production in small scale batch fermenter (Erlenmeyer flask) using meat processing waste medium. The experiments have been conducted with varying the concentrations of glucose, protein, and lactic acid. A mathematical model has been developed to describe growth rate, products (pediocin and lactic acid) formation rate, and substrates (glucose and protein) utilization rate. Monod model for dual substrates (glucose and protein) has been used with considering lactic acid inhibition. Luedeking-Piret model has been introduced to describe the production of pediocin and lactic acid. Results:The values of kinetic parameters have been determined using experimental data and model equations. The model prediction has been compared satisfactorily with the experimental data for the validation of the model. Conclusions:The developed model was satisfactorily validated to scale up the production of pediocin.

“…However, the production cost of bacteriocin production is an important economic factor that determines the industrial application of these biomolecules. For this reason, the main factors that influence the synthesis of bacteriocins (e.g., culture conditions and media composition) must be studied in depth to generate the necessary knowledge to optimize the production of these antibacterial compounds [73,75,187,[191][192][193].…”

“…Other important aspect that must be considered for optimizing the production of highly concentrated probiotic cultures is the development of a suitable nutrient feeding strategy, in order to avoid both overfeeding and underfeeding of nutrients, which are detrimental to biomass and product synthesis [193]. For this purpose, development of the corresponding mass balance equations is necessary to calculate the adequate volumes of feeding substrates that must be added to the growing culture in order to avoid the manifestation of growth inhibition phenomena such as substrate inhibition [219] or nutrient depletion [220].…”

The main purpose of this work is to give an overview on the chemical engineering aspects related with the production of probiotic cultures and bacteriocins. Firstly, some evidence of the potential of different Lactococci and Lactobacilli strains for prevention or treatment of different human diseases, or as growth promoters in farm animals is given. In addition, examples of different commercial dietary supplements containing probiotic lactoccocci and lactobacilli in combination or not with other probiotic bacteria are presented. Secondly, the main factors (cultivation method, culture media, and media composition) affecting the production of bacteriocins by lactoccocci and lactobacilli strains are showed. Examples of modelling procedures developed to describe the production of higher concentrations of biomass and bacteriocins in fed-batch cultures subjected or not to successive alkalizations are summarized. Finally, the corresponding mass balance equations performed in the latter cultures are presented to calculate the volumes of feeding substrates and the concentrations of nutrients (lactose, glucose, proteins, nitrogen, and phosphorous) added to the fermentation medium, as well as the concentrations of biomass and products in the fermentor just after each feeding.
