IMMOBILISASI BAKTERI PADA KITOSAN-ALGINAT DAN KITIN-ALGINAT

Eva Oktarina, Rizki Adrianto, Ira Setiawati

Sari


Imobilisasi bakteri merupakan pelapisan bakteri dengan senyawa organik atau anorganik yang bertujuan untuk penangkapan bakteri, sehingga bakteri dapat lebih bertahan pada kondisi lingkungan yang kurang adaptif. Tulisan ini bertujuan untuk membahas imobilisasi bakteri (Serratia sp., Pseudomonas sp., dan Enterobacter sp.) pada kitosan-alginat dan kitin-alginat serta penggunaannya pada penurunan kadar sianida pada limbah cair tapioka (skala laboratorium). Pengukuran sianida dilakukan dengan spektrofotometer. Pada skala laboratorium, hasil menunjukkan keenam bakteri terimobilisasi, yaitu : Serratia 1-kitosan-alginat, Serratia 1-kitin-alginat, Serratia 2-kitosan-alginat, Serratia 1-kitin-alginat, Pseudomonas-kitosan-alginat, Pseudomonas-kitin-alginat, Enterobacter-kitosan-alginat, dan Enterobacter-kitin-alginat dapat menurunkan kadar sianida pada limbah cair tapioka.

Kata Kunci
