Effects Of pH, Temperature And Salinity In Growth And Organic Acid Production Of Lactic Acid Bacteria Isolated From Penaeid Shrimp Intestine

Abstract: 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 inte… Show more

“…Carboxymethyl Cellulose (CMC) media is an anionic polymer that is commonly used in cellulase activity testing [16]. Cellulase-producing bacteria growth on BSM-CMC-CR media containing potassium phosphate which plays a role in increasing the growth and density of bacterial cells [17] while magnesium sulfate has a role as a nutrient for bacteria to grow and develop. CMC is the most appropriate substrate that able to induce bacteria to produce cellulase enzymes.…”

“…Adanya feses, sisa pakan, serta sisa metabolit cultivan dapat menjadi sumber makanan bagi bakteri [33]. Faktor lingkungan dapat mempengaruhi pertumbuhan bakteri diantaranya yaitu pH, suhu dan salinitas [34]. Faktor yang dapat memicu perkembangan total bakteri dalam media budidaya udang vaname yaitu manajemen pakan yang benar dan efektif serta pergantian air [35].…”

“…Hal ini karena adanya faktor PH, salinitas dan suhu. Menurut Subagiyo et al (2015) kondisi yang baik untuk pertumbuhan bakteri asam laktat dapat berbeda dengan kondisi baik untuk produksi bakteri asam laktat. Selain itu, usia ayam petelur yang digunakan dalam perlakuan dapat mempengaruhi jumlah BAL yang dihasilkan.…”
