Gluconacetobacter xylinus Tarafından Üretilen Saf Bakteriyel Selülozun Kuru ve Yaş Formları ile Boya Uzaklaştırılması

Bakteriyel selüloz farklı alanlarda kullanılmaktadır. Bu alanlardan biri, bu malzemeyi farklı boyaların renklerinin giderimi için biyoadsorban olarak kullanmaktır. Çalışmada, bakteriyel selüloz (BS) elde etmek için Gluconacetobacter xylinus kullanılmıştır. BS'nin yaş ve kuru formları, Reaktif Mavi 171 (CI Chrocion Mavi HERD) (200 mg/L), Remazol Parlak Mavi R' nin (150 mg/L) (C. I Reaktif Mavi 19) ve Chrocion Yeşil H-E4BD (100 mg/L) boyalarının uzaklaştırılması için biyoadsorban olarak kullanıldı. En yüksek renk giderme oranları, ilk kullanımda yaş BC ile 30°C, 150 rpm'de 24 saat inkübasyondan sonra CBHERD, RBBR ve CH Yeşil boyaları için sırasıyla %51, %52 ve %54 olarak elde edilmiştir. Bu değerler ilk kullanım sonunda BC’nin kuru formları için %11, %21 ve %20 idi. Aynı zamanda bakteriyel selülozun yapısı ve morfolojisi SEM, XRD ve FTIR analizleri ile belirlendi.

Dye Removing with Dry and Wet Forms of Pure Bacterial Cellulose Produced by Gluconacetobacter xylinus

Bacterial cellulose is being used in the different areas. One of these areas is using this material as bioadsorbent for decolorization of the different dyes. In the study, Gluconacetobacter xylinus was used for obtaining bacterial cellulose (BC). The wet and dry forms of the BC were utilized as bioadsorbent for removal of the Reactive Blue 171 (C.I Chrocion Blue HERD) (200 mg/L), Remazol Brilliant Blue R (150 mg/L) (C. I Reactive Blue 19), and Chrocion Green H-E4BD (100 mg/L) dyes. The highest decolorization rates were obtained with wet BC at the first use as 51%, 52% and 54% for CBHERD, RBBR and CH GREEN dyes after 24 hours of incubation at 30°C, 150 rpm, respectively. These values were 11%, 21% and 20% for dry forms of BC at the end of the first use. At the same time, the structure and morphology of bacterial cellulose were determined by SEM, XRD and FTIR analysis.
