Abstract

Lindi hitam merupakan limbah industri pulp yang belum termanfaatkan dengan baik. Pemanfaatan lignin dari lindi hitam selama ini biasanya hanya digunakan sebagai perekat. Dalam bidang mikrobiologi lignin dari lindi hitam dapat dimanfaatkan sebagai media selektif untuk isolasi jamur pelapuk putih. Tujuan penelitian ini adalah untuk mengetahui manfaat lignin hasil isolasi proses biopulping sebagai media selektif untuk jamur pelapuk putih. Lignin dari lindi hitam hasil biopulping bambu, dengan proses pemasakan soda dan kraft, diisolasi dengan penambahan asam. Padatan lignin kemudian dimurnikan menggunakan larutan dioksan dan ditimbang berat serta dianalisa secara kualitatif menggunakan spektrofotometer. Lignin hasil isolasi ditambahkan pada media agar untuk uji selektifitas jamur pelapuk putih Phanerochaete crysosporium dan Trametes versicolor. Pretreatment bambu pada 30 hari inkubasi menghasilkan lignin yang lebih tinggi jika dibandingkan dengan inkubasi selama 45 hari. Padatan lignin yang diperoleh dari hasil biopulping proses kraft juga lebih tinggi jika dibandingkan pada proses soda. Pengujian selektifitas jamur pada media alkali lignin menunjukkan bahwa fungi T. versicolor mensekresi enzim lebih cepat daripada P. chrysosporium.

Abstract

Single and mix cultures of white-rot fungi Trametes versicolor and Pleurotus ostreatus has been applied onto sugarcane bagasse as a pretreatment process. The purpose of this research was to investigate the effect of single and mix cultures of white-rot fungi in lignin degradation while maintaining minimum loss of ?-cellulose of sugarcane bagasse. Single and mix cultures of white-rot fungi T. versicolor and P. ostreatus have been inoculated onto sugarcane bagasse which varied in 5%, 10%, and 15% (w/v) with inoculum comparison 1:1. After 4-week incubation, analysis was carried out on the content of extractives, lignin, ?-cellulose and hemicellulose. The result showed that 4-week incubation of single culture of P. ostreatus was more advantageous as a pretreatment method for sugarcane bagasse, with considerable number of lignin degradation (17,95%) and minimum loss of cellulose (11,00%) and hemicelluloses (5,75%). As with mix cultures, incubation period should have been reduced to prevent significant loss of cellulose and hemicellulose. Furthermore, with shorter incubation period, this biological pretreatment process will be more interesting and feasible for the industry.

Abstract

Water pollution by dyes represents from dyestuff industry becomes an environmental concern. Finding new isolates capable of decolorizing these dyes is important. The study aimed to assess the new isolates of white-rot fungi (WRF) as decolorizing agent of anthraquinone and azo dyes. Decolorization assay were conducted in Agar plates and liquid medium. During the decolorization, laccase activities produced by the fungal strains were analyzed. Identification of the fungal strains were investigated using molecular DNA analysis. The results showed that isolates M3, H18, and GP1 were able to decolorize anthraquinone and azo dyes in Agar and liquid medium. Based on DNA analysis, isolates M3, H18, and GP1 have the similarity to Trametes sanguinea, Trametes polyzona, and Neofomitella guangxiensis, respectively. Among the fungi, T. polyzona H18 exhibited high decolorization ability (70–90%) to the dyes (100 mg/L) after 96-hours incubation. Laccase activity was fluctuated during the reactions with tendency to increase at the beginning until its peak, then decreased at the end of incubation. This study demonstrated the potential of the new isolates from Indonesia to decolorize anthraquinone and azo dyes. The results of the study can provide an alteranative for bioremediation agents of contaminated water by synthetic dyes.

Abstract

The ability of the tropical white-rot fungi and their enzyme to decolorize synthetic dyes was investigated. Production of lignin-modifying enzymes (LMEs) from the three new isolated fungi, namely Trametes hirsuta D7, Ceriporia sp. BIOM 3, and Cymatoderma dendriticum WM01 were observed for 9 days incubation under static condition. The results showed that the LMEs production enhanced in the present of guaiacol. T. hirsuta D7 produced only laccase (Lac), with the highest activity was 22.6 U/L on the 5th-day of the cultivation. At the same time, Ceriporia sp. BIOM 3 and C. dendriticum WM01 secreted both laccases (Lac) with the activities 0.2 U/L and 1.0 U/L, respectively, and manganese peroxidase (MnP) with the activities 0.1 U/L and 1.0 U/L, respectively. Among the fungi, T. hirsuta D7 efficiently degraded 65% Remazol Brilliant Blue–R (RBBR) dye within 72 h using the only laccase. This study shows that laccase may have a major role in synthetic dyes' decolorization process, followed by MnP and LiP.

Abstract

The ability of ligninolytic enzymes from Trametes hirsuta D7 to decolorize several synthetic dyes was investigated. A crude enzyme powder was produced by fermenting oil palm empty fruit bunch fibers for one month. The dye decolorization by the enzymes occurred at an efficient 0.25 U/mL. The enzymes degraded 100, 200, 300, 400, and 500 ppm Remazol Brilliant Blue R (RBBR) within 7 h by 95.57 ± 0.32%, 93.46 ± 3.09%, 91.84 ± 0.65%, 86.44 ± 0.97%, and 82.14 ± 0.52%, respectively. The enzyme also decolorized anthraquinone (Acid Blue 129), monoazo (Acid Orange 7), diazo (Reactive Black 5), and trimethyl methane (Methyl Violet) dyes within 7 h by 94.59 ± 7.97%, 13.99 ± 0.30%, 7.61 ± 0.01%, and 7.59 ± 0.18%, respectively. Addition of MnSO4, H2O2, and violuric acid enhanced the dye decolorization rate by up to 10-fold. This study shows the potential for application of ligninolytic enzymes from T. hirsuta D7 in the treatment of wastewater effluent of textile industries.
