Abstract
The goal of this study was to use a microencapsulation technology to prepare air-dried concentrated cultures of Lactobacillus rhamnosus R0011. The cultures were microencapsulated in alginate beads, which were added to a growth medium to allow cell multiplication inside the matrix; the beads were recovered, dipped in protective solutions, and air-dried. The effects of fermentation technology and of the composition of the protective solutions on subsequent survival during air-drying were examined. The cells prepared under a constant pH of 6.2 had only 2.5% survival to air-drying at 25 °C when the protective solution was composed of sucrose and phosphate. Allowing the pH to drop to 4.2 during the biomass production step and using a protective medium composed of glycerol, maltodextrin, yeast extract, and ascorbate increased survival to 20%. If the ingredients of the protective medium at the beginning of drying were concentrated at a water activity of 0.96 rather than 0.98, survival during air-drying increased further to 56%. This rate was similar to that of a traditional freeze-drying process. These data suggest that applying a combination of acid and osmotic stresses to L. rhamnosus R0011 cells improves their subsequent stability during the air-drying process. Dried microencapsulated cultures having 2.6 × 1011 CFU·g-1 were obtained.

Abstract
The objective of the study was to develop calcium alginate films, containing Lactobacillus plantarum ATCC 8040 with preserved and stable viability and antibacterial activity. L. plantarum-loaded films containing different calcium concentrations were physically characterized for mechanical and bioadhesive properties and lactobacilli release. The viability and antibacterial activity of L. plantarum was studied before and after processing, and during 6 months of storage. A multiresistant clinical isolate, VIM-2-metalo-β-lactamase producing Pseudomonas aeruginosa, was used as an indicator strain. Interference between L. plantarum and films enhanced films elasticity, water absorption ability, release of lactobacilli, and decreased films adherence. A decrease of L. plantarum viability in alginate films (≤1 log unit) was observed after freeze drying. L. plantarum, at cell concentrations of 108 cfu/ml, was inhibitory active. The viability and antibacterial activity of the immobilized lactobacilli remained stable during 6 months of storage. The study has proved the potential of alginate films to deliver L. plantarum in high numbers to individuals.

Abstract
The aim of this research was to produce concentrated biomasses of thermophilic lactic starters using immobilized cell technology (ICT). Fermentations were carried out in milk using pH control with cells microentrapped in alginate beads. In the ICT fermentations, beads represented 17% of the weight. Some assays were carried out with free cells without pH control, in order to compare the ICT populations with those of classical starters. With Streptococcus thermophilus, overall populations in the fermentor were similar, but maximum bead population for (8.2 x 10(9) cfu/g beads) was 13 times higher than that obtained in a traditional starter (4.9 x 10(8) cfu/ml). For both Lactobacillus helveticus strains studied, immobilized-cell populations were about 3 x 10(9) cfu/g beads. Production of immobilized Lb. bulgaricus 210R strain was not possible, since no increases in viable counts occurred in beads. Therefore, production of concentrated cell suspension in alginate beads was more effective for S. thermophilus. Photomicrographs of cells in alginate beads demonstrated that, while the morphology of S. thermophilus remained unchanged during the ICT fermentation, immobilized cells of Lb. helveticus appeared wider. In addition, cells of Lb. bulgaricus were curved and elongated. These morphological changes would also impair the growth of immobilized lactobacilli.

Abstract
The effects of chitosan and alginate coatings of alginate beads with entrapped Lactococcus lactis ssp. lactis were studied in batch and continuous fermentations. Chitosan coating reduced the final concentrations of free cells, the initial release of free cells and the rate of lactate production in milk fermented batch-wise to a final pH of 4.7 in five consecutive batch fermentations. An alternative experimental system based on continuous fermentation with controlled pH and a high dilution rate was developed to better study the phenomenon of cell release. To estimate the effects of different bead coatings on cell release, alginate beads were coated with chitosan or alginate, or sequentially with chitosan/alginate or chitosan/alginate/chitosan. Chitosan coating alone seemed to reduce the rate of cell release only in the early stages of the fermentation, while sequential coatings with chitosan and alginate showed significant reduction throughout the whole test period. To examine whether the observed effects of bead coating could be explained only by a decrease in cell activity, the ratios between the rate of cell release and the rate of lactate production were examined during the fermentations for the different beads. This ratio showed qualitatively the same behavior as direct results of volumetric cell release.

Abstract
Lactococcus lactis subsp. cremoris was microencapsulated within alginate/poly-L-lysine (alg/PLL), nylon or crosslinked polyethyleneimine (PEI) membranes. Toxic effects were observed with solvents and reagents used in nylon and PEI membrane formation. Alg/PLL encapsulation resulted in viable and active cell preparations which acidified milk at a rate proportional to the cell concentration, but at rates less than that of free cell preparations. At 4 x 10(8) colony-forming units (cfu/ml milk), encapsulated cells took 17 per cent longer than free lactococci to reduce the pH of milk to 5.5. Similar activities of free and micro-encapsulated cells may be attained at higher cell concentrations (10(9) cfu/ml milk). The rate of lactic acid production was approximately 2 mmol/h at an encapsulated cell concentration of 4 x 10(8) cfu/ml.

Abstract
The potential applications of immobilized cell technology (ICT) to the dairy industry are examined. Immobilization modifies the physiology of cells, and the consequences of ICT on lactose as well as citrate metabolism are reviewed. Immobilization also affects the sensitivity of lactic acid bacteria (LAB) to salt and penicillin. ICT can be used to produce starters for the dairy industry, and aspects of biomass production in beads, continuous cell release from beads, and continuous fermentations with filtration cell recycle are examined. Potential applications of ICT to the dairy industry include acidification of raw milk prior to ultrafiltration, inhibition of psychrotrophic bacteria in raw milk, yogurt production, cheese manufacture, and cream fermentations. Impacts of yeast, bacterial, or bacteriophage contaminations in ICT processes as well as their control are discussed.

Abstract
Methods to encapsulate biological materials are now widely used. Sometimes bioencapsulation is considered as a universal technique conducting to identical results independently on the biological material used. For instance, a similar behavior is frequently waited for different strains of immobilized microorganisms without taking into account substantial differences in its physiological and morphological characteristics. Often interactions with the matrix support are also neglected. Thus, some concepts developed throughout all these years working in bioencapsulation merits to be revisited.
