Abstract
Enzim fibrinolitik merupakan kelompok protease serin memiliki
kemampuan untuk menghancurkan bekuan darah dalam berbagai jenis
penyakit thrombosis seperti infark miokard akut. Mekanisme kerja
enzim fibrinolitik dengan menghidrolisis fibrin yang menyebabkan
bekuan darah menjadi produk terlarut yang dapat dibuang dari
peredaran darah sehingga membebaskan pembuluh darah dari bekuan
darah lalu memulai proses penyembuhan dinding pembuluh darah.
Pemanfaatan bakteri sebagai penghasil enzim fibrinolitik dapat berasal
dari limbah. Limbah cair industri kecap memiliki kandungan protein
sehingga dapat digunakan sebagai sumber isolat bakteri fibrinolitik.
Tujuan penelitian ini untuk mengetahui aktivitas fibrinolitik isolat
bakteri limbah cair industri kecap.
Penelitian ini menggunakan isolat bakteri dari limbah cair
industri kecap. Metode diawali dengan pengambilan sampel, isolasi
bakteri,
identifikasi bakteri, pembuatan ekstrak kasar enzim,
pemurniaan ekstrak kasar enzim, pembuatan sampel uji dan penentuan
potensi fibrinolitik menggunakan metode clot lysis. Hasil persentase
(%) lisis bekuan darah.yang dihasilkan menunjukkan kemampuan
ekstrak enzim dalam mendegradasi fibrin. Analisis data menggunakan
cara pendekatan statistik two way ANOVA.
Hasil uji proteolitik bakteri yang diisolasi dari limbah cair
industri kecap menghasilkan 4 koloni yang memiliki aktivitas
proteolitik. Hasil identifikasi pewarnaan Gram menunjukan 3 bakteri
Gram positif dan 1 bakteri Gram negatif. Ekstrak kasar enzim
fibrinolitik yang berasal dari bakteri limbah cair industri kecap mampu
melisiskan gumpalan darah. Konsentrasi optimal ekstrak kasar enzim
fibrinolitik sebagai agen fibrinolitik secara in vitro pada setiap koloni
yaitu konsentrasi 80%.
Fibrinolytic enzymes are a group of serine proteases that have
the ability to destroy blood clots in various types of thrombosis diseases
such as acute myocardial infarction. The mechanism of action of
fibrinolytic enzymes is by hydrolyzing fibrin that causes blood clots
into soluble products that can be removed from the blood circulation,
thus freeing blood vessels from blood clots and then starting the healing
process of the blood vessel wall. The utilization of bacteria as
fibrinolytic enzyme producers can be derived from waste. Soy sauce
industry liquid waste has protein content so that it can be used as a
source of fibrinolytic bacterial isolates. The purpose of this study was
to determine the fibrinolytic activity of bacterial isolates of soy sauce
industry liquid waste.
This study used bacterial isolates from soy sauce industry liquid
waste. The method begins with sampling, isolation of bacteria,
identification of bacteria, preparation of enzyme crude extract,
purification of enzyme crude extract, preparation of test samples and
determination of fibrinolytic potential using the clot lysis method. The
results of the percentage (%) of blood clot lysis produced indicate the
ability of the enzyme extract to degrade fibrin. Data analysis using two
way ANOVA statistical approach.
The results of the proteolytic test of bacteria isolated from soy
sauce industry liquid waste produced 4 colonies that had proteolytic
activity. Gram stain identification results showed 3 Gram positive
bacteria and 1 Gram negative bacteria. Crude extract of fibrinolytic
enzyme derived from soy sauce industry liquid waste bacteria is able to
lyse blood clots. The optimal concentration of fibrinolytic enzyme
crude extract as a fibrinolytic agent in vitro on each colony is 80%
concentration.
