Listeria Species

Silage samples representing approximately 10% of Vermont's dairy farms were tested for the presence of Listeria species. Listeria innocua was isolated from 15.3% of the silage samples, while Listeria monocytogenes was isolated from 2.9% of the examined samples. As silage pH increased, the incidence of Listeria increased concomitantly. Seventy-eight mesophilic lactic acid bacteria, indigenous to silage, were screened for specific and nonspecific antagonism against four L. monocytogenes indicator strains. Most of the silage isolates demonstrated nonspecific inhibition via lactic acid production against the L. monocytogenes indicator strains. None of the indigenous silage isolates tested in this survey demonstrated specific antagonism via production of bacteriocinogenic compounds.

Distiller's Grain

Lactic acid production using Lactobacillus casei and Streptococcus thermophilus individually or as mixed culture on distiller’s grain in open fermentation conditions was evaluated. Lactic acid production and residual sugar were the main features examined. Increased lactic acid production was observed, when mixed cultures were used in comparison to individual ones. This revealed possible synergistic effects between the two lactic acid bacteria.

Four lactic acid bacteria (LAB) strains named HN78, HN87, HN91 and HN113 were separated fromStylosanthes guianensis SW. of Hainan province, which were identified bacterially using the classical classification and the sequences of 16S rDNA. The results showed that four strains wereEnterococcus hirae,Enterococcus faecalis,Lactococcus lactisandLactobacillus plantarum. The capability of lactic acid production of HN113 and HN91 were better than HN78 and HN87.

The inhibition of lactic acid bacteria by quaternary ammonium compounds in milk has been shown to be an effect on acid production and not upon growth. Lactic acid production is affected by concentrations of 2.5 – 10 ppm, while growth is not affected unless the concentration is 25 – 50 ppm.

Bakteri asam laktat telah lama dikembangkan sebagai probiotik. Penentuan kondisi lingkungan yang optimum untuk pertumbuhan sel serta asam organik memberikan gambaran aktivitas optimum untuk kinerja probiotik baik dalam sistem fisiologi inang maupun dalam sistem bioproses untuk produksi sel dan metabolit. Penelitian ini bertujuan untuk mengetahui pengaruh faktor lingkungan (pH, suhu dan salinitas) terhadap pertumbuhan dan produksi total asam organik tiga isolat bakteri asam laktat yang telah diseleksi dari intestinum udang penaeid. Eksperimen menggunakan  medium deMan, Rogosa and Sharpe (MRS) cair. Perlakuan pH awal meliputi  nilai pH 4, 5 dan 6. Perlakuan suhu meliputi suhu 25, 30 dan 35OC serta perlakuan salinitas  meliputi salinitas 0,75 %, 1,5 % dan 3 %.  Setiap interval 6 jam dilakukan pengambilan sampel kultur bakteri dan penghitungan pertumbuhan berdasarkan perubahan optical density (pada panjang gelombang 600 nm) sedangkan produksi asam laktat dianalisis dengan metode titrimetrik menggunakan NaOH 1 N sebagai larutan titrasinya. Berdasarkan hasil penelitian disimpulkan bahwa suhu, pH awal dan salinitas berpengaruh terhadap pertumbuhan dan produksi asam organik. Nilai kondisi lingkungan terbaik untuk pertumbuhan dapat berbeda dengan nilai terbaik untuk produksi asam organic. Hal ini ditunjukan oleh nilai laju pertumbuhan dan produksi asam laktat tertinggi dari tiga isolat uji terjadi pada suhu, pH awal dan salinitas yang berbeda.  Isolat L12 tumbuh optimum pada suhu 30oC, pH awal 6 dan salinitas 0,75%. Isolat L14 tumbuh optimum pada suhu 30oC, pH awal 6 dan salinitas 1.5%. Isolat L 21 tumbuh optimum pada suhu 30 oC, pH awal 6 dan salinitas 1.5%. Kata kunci: bakteri asam laktat, suhu, pH, salinitas, asamorganik, pertumbuhan, Lactic acid bacteria are widely distributed in intestinal tracts of various animals where they live as normal flora.Strains of lactic acid bacteria are the most common microbes employed as probiotics, The optimum condition for growth are important to mass production and to determined parameters most suitable for growth. The effects of  temperature, pH and salinity on the growth and production of lactic acid from the three shrimp intestinal lactic acid bacteria isolates were conducted using bacth culture in a flask. These variables for growth were determined based on the growth curves and lactic acid production. Data from the flask batch experiment demonstrated that the best initial pH and temperature  for growth of isolat L12 ,L14 and L21 were found to be pH 6 and 30 OC.  Salinity (NaCl concentration) 0,75% were the best for growth of isolat L12. Salnity  1,5 % were best for growth of isolat L14 and L21. Key words : growth, temperature, pH, salinity, lactic aid bacteria
