“…During storage under refrigeration, the increase of pH in meat samples of treatments was directly related to the multiplication of psychrotrophic and mesophilic microorganisms, and associated to autolytic reactions which result in basic compounds that increase the pH. Later on, the proteolytic action of spoilage bacteria also provokes the same effect (20). As to the total acidity of the samples during storage, only a slight variation was observed: it varied between 0.8 and 1.2, in samples submitted to the three treatments.…”

Sugar cane molasses is a cheap by-product of the sugar cane industry. This product was used for growth and production of bacteriocins by Lactobacillus plantarum BN and evaluated for its potential application in the extension of the shelf-life of raw meat. Bovine meat cubes were dipped in the filtered and neutralized supernatant of the fermented broth (Treatment A) and stored at 5ºC. Counts of psychrotrophic and mesophilic aerobic microorganisms, pH determination and total acidity were performed on meat cubes after 0, 3, 6, 9, 12 and 15 days. These determinations were also done in cubes dipped in a 6% lactic acid solution (treatment B) and distilled water (treatment C). After 3 days, the counts of psychrotrophic microorganisms in cubes submitted to treatment A, B and C increased 0.38, 1.42 and 2.04 log cycles, respectively. The same happened with mesophilic microorganisms (0.31, 0.33 and 1.04 log cycles increases, respectively). On the sixth day, the psychrotrophic population in samples submitted to treatments A and B were 2.07 and 0.64 log cycles, respectively, lower than in the control samples (treatment C). Mesophilic microorganisms in these samples were 1.58 and 1.12 log cycles, respectively, lower than the controls. On the sixth day, only samples submitted to treatment A presented lower counts than those recommended by ICMSF as quality standards for raw meat (<10 7 CFU/g). After nine days of storage under refrigeration, samples submitted to treatment A still maintained acceptable quality. From the twelfth day on, all samples exceeded the microbial quality limits. These results indicate that dipping of raw meat in filtered sugar cane molasses containing bacteriocins produced by L. plantarum BN may be an interesting technological option to extend the shelf life of refrigerated bovine meat.

“…Recently, sugar cane molasses, a cheap by-product of the sugar cane industry, was shown to be a good substrate for the growth of bacteria, such as Micrococcus varians (17), Pediococcus pentosaceus (25), Pediococcus acidilactici (20) and Lactobacillus plantarum BN (6).…”

“…P. acidilactici G24, when used as a silage inoculant, was found to grow on glucose and fructose with a short lag phase, a rapid acid production rate, and was able to grow within a broad range of pH and temperature (Fitzsimons et al, 1992). The ability of P. acidilactici IL01 to grow on MRS broth substituting glucose with sugar cane molasses (Sant'Anna and Torres, 1998) also suggests that the efficiency of sugar utilization is strain-specific for P. acidilactici.…”

Growth stimulating effects of LYCH leaf hydrolysates on Pediococcus acidilactici IMT101 cells were observed when MRS broth was supplemented with 20% (v/v) H1+H2, the mixture of hydrolysates prepared by a traditional tea-making process. Cells grown on MRS containing H1+H2 showed a shortened lag phase while yielding a cell concentration (X(s)) significantly higher than other conditions investigated entering stationary phase. The maximal specific growth rate (mu(max)) was also the highest among all. Microwave-assisted extraction (MAE) at 80 degrees C for 2h (M80(2h)) released more amino acids but less sugar (fructose, glucose, and sucrose) than in H1+H2. Both X(s) and mu(max) reached in M80(2h)-supplemented MRS broth were lower than those in MRS containing H1+H2. No correlations between amino acids and cell growth were found. P. acidilactici cells grown in MRS broth in general showed higher consumption of carbohydrate in comparison with those in M17 broth containing the same carbohydrate. In the absence of FOS, the increased glucose concentration in MRS when supplemented by H1+H2 hydrolysates appeared to be responsible for the stimulatory effects on P. acidilactici growth. The growth-enhancing effects of LYCH leaf hydrolysates indicate the potential of developing new applications for LYCH leaves in promoting the growth of other probiotic cells using a simple process.

The actinomycete strain Lg, which was isolated from groundwater contaminated with leachate flowing out of a former municipal landfill site (upstate Sa˜o Paulo, Brazil) and found to produce exopolysaccharides, was analysed by polyphasic taxonomy. The growth of this strain on sugarcane molasses, at various concentrations from 2% to 10%, and on the standard glucose-yeast-maltose (GYM) medium was observed by monitoring the optical density of the culture at 600 nm. Lg was found to be Gram-positive, catalase-positive, oxidase-negative, non-motile, non-sporing and did not reduce nitrate. Morphological, biochemical, chemotaxonomic and molecular tests indicated that Lg has properties typical of Gordonia polyisoprenivorans and this new strain was thus named G. polyisoprenivorans CCT 7137. Growth of the bacterium in the experimental media was notably affected by the molasses content, being fastest at 2% and 3%, the lowest contents, the maximum specific growth-rates being 0.157 h )1 and 0.168 h )1 , respectively. These rates were greater than those achieved at higher concentrations and of the same order as the rate in GYM medium, 0.175 h )1 . CCT 7137 is one of six strains of G. polyisoprenivorans so far isolated and recorded in the literature, and one of the two found in contaminated groundwater. This is the first known study of the growth of a strain of G. polyisoprenivorans in GYM medium and on sugarcane molasses as sole source of nutrients. The latter is proposed as a potential substrate for production of this strain.
