DIVERSITAS MIKROORGANISME PADA GRAIN KEFIR
Abstract
Grain kefir yang digunakan pada pembuatan produk kefir memiliki mikroba yang komplek dan beragam. Tujuan dari artikel ini adalah untuk meninjau tentang diversitas mikroba pada grain kefir yang berkaitan dengan faktor-faktor yang mempengaruhi, komposisi dan metode dalam mengidentifikasi mikroba yang terdapat pada grain kefir. Metode yang digunakan dalam menyusun artikel ini adalah telaah sistematis (systematic review) terhadap hasil-hasil penelitian yang terkait dengan diversitas mikroorganisme pada grain kefir. Penelitian ini menunjukkan terdapat banyak factor yang dapat mempengaruhi diversitas microbiota grain kefir yaitu wilayah geografis, mikroba asal, pemeliharaan, kondisi penyimpanan, rasio grain dan susu, waktu dan suhu inkubasi, sanitasi, dan susu yang digunakan. Artikel ini juga menuliskan tentang metode molekuler seperti: amplifikasi berbasis Polymerase Chain Reaction (PCR), pengurutan gen 16S rRNA dan Denaturing Gradient Gel Electrophoresisi (DGGE) dalam mengidentifikasi mikroba dalam grain kefir.
