The Production of Tannin Acyl Hydrolase from Aspergillus niger

Abstract

The aim of this research was to produce tannin acylhydrolase (tannase) from Aspergillus niger isolated from cacao pod. The first step of the study included determination of optimal pH, temperature, and incubation period to produce tannase. Optimal conditions obtained for tannase production were pH 5.5, a temperature of 28 o C and an incubation period of 3 days. Optimization of production medium was conducted. The media tested were solid and liquid wheat flour media with a concentration of tannic acid as inducer at 0, 3, 5, and 7% (wt/vol). The best production medium was solid medium with tannic acid concentration of 5% (wt/vol).

STUDI KATALITIK HERBAL PEMANFAATAN TANAMAN BROTOWALI (Tinospora cordifolia) SEBAGAI OBAT PENURUN KADAR GLUKOSA DARAH (Diabetes Mellitus)

“…Pemanfaatan tanaman Brotowali sendiri banyak terdapat pada bagian daun [28] dan batangnya [29] karena pada bagian ini mengandung flavonoid [30], alkaloid [31], saponin [32] dan tannin [33]. Bagian batang Brotowali sendiri dimanfaatkan untuk penyakit rematik [34], demam [35], sakit kuning [36], batuk [37] dan cacingan [38].…”
