Abstract:
... The growth of a Pseudomonas sp., an Enterobacter sp., Kurthia zopfii, Microbacterium thermosphactum and a Lactobacillus sp. in pure culture on porcine muscle at 16 and 2° was examined in both open and gas-tight systems. The CO₂ in the headspace of the gas-tight containers was produced by the muscle and by the bacteria. The Gram negative bacteria produced much lower amounts of CO₂ than the Gram pos ...

Abstract:
... A plating procedure simulating conditions in ripening Cheddar cheese was used to isolate microorganisms in young cheese that grow at ordinary ripening temperatures. Forty-one commercial cheese samples, most 7 days old, were obtained from ten Iowa manufacturing plants. Samples were plated in special Trypticase-soy agar, covered with 50 ml of 1.5% (w/v) agar, and incubated at 7.2 C for 3 months. Fol ...

Abstract:
... An alpha-amylase (E.C. 3.2.1.1.) secreted by Lactobacillus amylovorus was partially purified and characterized. This high-molecular-weight enzyme [Imam SH, Burgess-Cassler A, Cote GL, Gordon SH, Baker FL (1991) Cuff Microbiol 22:365-370] was quantified with a clinical alpha-amylase assay adapted to a microplate format. It was isolated from concentrated cell-free culture medium by ammonium sulfate ...

Abstract:
... Curvacin A is a bacteriocin produced by Lactobacillus curvatus LTH1174 which is a potential starter organism for the production of fermented dry sausages. This peptide inhibits the growth of the opportunistic food pathogens Listeria monocytogenes and Enterococcus faecalis and thus, curvacin A may enable better performance of a starter and improvement of the hygienic status of meat products.

Abstract:
... The growth kinetics in batch culture of 6 strains, potentially useful as starter cultures for ewe's cheese-making, has been analysed. Under the experimental conditions used a high conversion of carbohydrates into lactic acid was achieved. The production of lactic acid can be used as an indirect biomass measurement. Two mathematical models (Logistic and Gompertz's) have been used to describe the gr ...

Abstract:
... The feasibility of conversion of soy molasses, a low value by-product of soy protein production, to lactic acid by fermentation with Lactobacillus salivarius was investigated. The basic environmental parameters affecting growth and lactic acid production were determined. Lactic acid production in soy molasses was optimal at pH 5.6 and 42 degrees C. Addition of 0.5% yeast extract to soy molasses re ...

Species of Lactobacillus were isolated and identified from commercial Washington state grapes and wines including L. brevis (4 strains), L. hilgardii (4), L. plantarum (3), and L. fructivorans (1). Unlike other strains, L. brevis and L. plantarum grew in media at relatively low pH (pH 3.16 and 3.34). Sulfur dioxide inhibited all strains as growth was delayed in 33 mg/L total SO2 (pH 3.5). None of ...

Abstract:
... The substrate specificity and catalytic activity of the dinucleotide-dependent L-2-hydroxyisocaproate dehydrogenase from Lactobacillus confusus (L-HicDH) have been altered by modifying an enzyme region which is assumed to be involved in substrate recognition. The design of the variant enzymes was based on an amino acid alignment of the modified region with the functionally related L-lactate dehydr ...
