MARIN A, Zaira T; CORTES R, Misael and MONTOYA C, Olga I. EVALUATION OF THE VIABILITY OF GROWTH OF THE NATIVE STRAIN Lactobacillus plantarum LPBM10 AND COMMERCIAL STRAIN Lactobacillus casei ATCC393 IN CAPE GOOSEBERRY PULP AND GLUCOSE ISOTONIC SOLUTION. Vitae [online]. 2009, vol.16, n.2, pp. 210-217. ISSN 0121-4004.
The aim of this work is to evaluate the survival of the strains Lactobacillus plantarum LPBM10 and Lactobacillus casei ATCC 393 in substrates of cape gooseberry pulp and glucose isotonic solution (14% w/w). A concentration of 0.5 is inoculated (McFarland scale) and it is stored at 4°C during 15 days. The counts were made from the dilution 108 in MRS agar, incubated at 37°C for 72 hours in microaerobic conditions. After 15 days counts in pulp and glucose solution are obtained, with averages for L. plantarum 3.23 ± 3.35 x 109 and 1.64 ± 1.57 x 109 CFU/mL and L. casei of 5.40 ± 2.36 x 108 and 7.34 ± 7.88 x 108 CFU/mL, respectively. The results show a good performance of both strains in the substrates, with levels above 106, approach considered in lacteous to define a food with probiotics. The development of these foods or substrates, are alternatives for direct consumption or impregnation solutions. This way allows the development of new products.
