a b s t r a c tThis paper presents a novel approach toward the production of hybrid alginate-lignin aerogels. The key idea of the approach is to employ pressurized carbon dioxide for gelation. Exposure of alginate and lignin aqueous alkali solution containing calcium carbonate to CO 2 at 4.5 MPa resulted in a hydrogel formation. Various lignin and CaCO 3 concentrations were studied. Stable hydrogels could be formed up to 2:1 (w/w) alginate-to-lignin ratio (1.5 wt% overall biopolymer concentration). Upon substitution of water with ethanol, gels were dried in supercritical CO 2 to produce aerogels. Aerogels with bulk density in the range 0.03-0.07 g/cm 3 , surface area up to 564 m 2 /g and pore volume up to 7.2 cm 3 /g were obtained. To introduce macroporosity, the CO 2 induced gelation was supplemented with rapid depressurization (foaming process). Macroporosity up to 31.3 ± 1.9% with interconnectivity up to 33.2 ± 8.3% could be achieved at depressurization rate of 3 MPa/min as assessed by micro-CT. Young's modulus of alginate-lignin aerogels was measured in both dry and wet states. Cell studies revealed that alginate-lignin aerogels are non-cytotoxic and feature good cell adhesion making them attractive candidates for a wide range of applications including tissue engineering and regenerative medicine.

Currently, approximately 2% of the produced lignin is utilized in value-added and commercial products (paper industries, medical, agriculture, fuel, chemical, concrete and cement, carbon fibers/nanotubes, board binder, dust controller, battery, cosmetics, foams, plastics, and heat), while the rest is burned to generate energy and recover chemicals (Khitrin et al 2012). However, this trend is changing due to the increasing interest in developing lignin-based products.…”

The feasibility of incorporating purified kraft lignin, at different concentrations ranging from 5 to 29%, into fiberboards made from corn residues was studied. The lignin was obtained from black liquor, which is a residue of the paper industry. Corn stalk raw material and its thermomechanically produced fiber were characterized in terms of their chemical composition. The physical and mechanical properties of the resulting fiberboards were evaluated. The fiberboards produced following a wet process had good mechanical and water resistance properties that satisfied the requirements of the relevant standards. In addition, a Life Cycle Thinking (LCT) approach suggested that lignin-based fiberboards are environmentally preferable than those based on thermosetting resins.

“…Pada penelitian proses pengomposan biomassa tanaman, termasuk TKKS, yang selama ini menjadi perhatian adalah bagaimana memahami beberapa bagian proses degradasi oleh mikroba yaitu degradasi selulosa dan hemiselulosa menghasilkan gula fermentasi melalui proses hidrolisis. Bagian proses degradasi yang juga sangat penting untuk dipahami adalah dekomposisi lignin (Khitrin et al 2012). Kandungan lignin TKKS mencapai 27,7% (Rosli et al 2017) yang harus dihilangkan sebelum terjadi proses degradasi selulosa dan hemiselulosa.…”

OPEFB (oil palm empty fruit bunch) could potentially be utilized as organic fertilizer or animal feed through composting. Information on microorganisms that play important roles in the natural decomposition of OPEFB is to date not much known yet. This research was aimed to obtain and, subsequently, to molecularly identify lignin-degrading microbial isolates responsible for naturally decomposing OPEFB in the Oil Plant Plantation and Palm Oil Refinery Plant, PTPN VIII Cikasungka, Bogor. Screening for active lignin-degrading isolates was carried out on 17 naturally decomposing OPEFB samples. A total of 19 isolates of fungi and 80 isolates of bacteria were obtained. Ligninolytic activity was measured by Sundman and Nase testing methods. Ligninolytic activity was found on 13 fungal isolates and 15 bacterial isolates. The active isolates were subsequently identified molecularly based on ITS sequence in the ribosome DNA area for fungi and in 16S rRNA genes for bacteria. The results showed that the lignin-degrading microorganisms obtained consisted of 5 bacterial isolates from the genus Bacillus and 3 fungal isolates from the genus Rhizopus and Aspergillus.ABSTRAK TKKS (tandan kosong kelapa sawit) berpotensi dimanfaatkan sebagai pupuk organik atau pakan ternak dengan cara pengomposan.

Penelitian ini bertujuan mendapatkan isolat mikroba pendegradasi lignin dalam pengomposan alami TKKS asal Perkebunan dan Pabrik Pemerasan Kelapa Sawit, PTPN VIII Cikasungka, Bogor, serta mengidentifikasi mikroba tersebut secara molekuler. Skrining mikroba aktif pendegradasi lignin dilakukan terhadap 17 sampel TKKS yang sudah lapuk secara alami. Sebanyak 19 isolat jamur dan 80 isolat bakteri telah dihasilkan. Aktivitas ligninolitik diukur dengan metode pengujian Sundman dan Nase. Isolat jamur yang memiliki aktivitas ligninolitik sebanyak 13 isolat, sedangkan bakteri sebanyak 15 isolat. Isolat-isolat aktif tersebut selanjutnya diidentifikasi secara molekuler berdasarkan pada sekuen ITS di daerah DNA ribosom untuk jamur dan menggunakan gen 16S rRNA untuk bakteri. Hasil menunjukkan bahwa 5 isolat bakteri yang memiliki kemampuan mendegradasi lignin berasal dari genus Bacillus, sedangkan 3 isolat jamur pendegradasi lignin berasal dari genus Rhizopus dan Aspergillus
