“…[30] The measured lipid contents in the present study are in consistency with that reported in Caulerpa racemosa, and Padina gymnospora, 19.1 %, and 11.4%, respectively However, they are upper than those determined previously for Ulva lactuca, (7.87-1.64 % DW) and (0.3-1.64% dry weight). [22,23,31] Presence of highest fat content of 21.25 mg/g in the seaweed E. compressa and a minimum of 11.67 mg/g in C. aerea of the current study closely depicting with the previous work carried out in this line.…”

ABSTRACT. Proximate composition of the three green seaweeds viz., Chaetomorpha aerea, Enteromorpha intestinalis, Enteromorpha compressa one brown seaweed Dictyota dichotoma and one red seaweed Gracilaria corticata was investigated by determination of protein, carbohydrates, lipid, moisture and ash content. In the present study, the total protein was recarded upper most in E. intestinalis and bare minimum in E. compressa. The maximum carbohydrates recorded in C. aerea and minimum in G. corticata. The lipid content was acquired upper limit in E. compressa and least in C. aerea. The ash and moisture content in following of 5 different seaweeds are as follows: 7.45mg/g, 3.91mg/g were recorded in the C. aerea, 8.52mg/g, 3.42mg/g in the E. intestinalis, 8.58mg/g, 3.75mg/g in the E. compressa, 9.47mg/g, 4.23mg/g in the D. dichotoma and 6.95mg/g, 3.98mg/g in G. corticata. The proximate composition of 5 different seaweed species exhibited high nutritional value for human consumption.

This work proposes a novel strategy to improve the continuous processing of wood slurries in hydrothermal liquefaction systems by co-processing with algae. Of all algae tested, brown seaweeds and microalgae perform best in preventing slurries dewatering, the main reason for pumpability issues with wood slurries. Rheological tests (viscosity-shear rate profile) indicate that the addition of these two algae to the wood slurry causes the highest increase in viscosity, which coincides with improved wood slurries stability and pumpability. Hydrothermal liquefaction of wood-algae slurries at 400 °C and 15 minutes in 10 mL tubular batch reactors shows that macroalgae slightly decrease the biocrude yield from 28.5 wt% to 21.6-25.5 wt% while microalgae increase the biocrude yield with more than 40 % relative to pure wood liquefaction. Another benefit of microalgae addition is that the total biomass loading and the organic mass fraction of the slurry can be increased by 100 % and 90 % respectively. Therefore, when co-processed with wood, microalgae can improve the wood feedstock pumpability, biomass loading, organic matter and the biocrude yield.

ABSTRAKRumput laut jenis Ulva lactuca dan Eucheuma cottonii merupakan rumput laut yang dapat dijumpai di perairan Indonesia, akan tetapi pemanfaatannya sebagai produk nori belum dilakukan. Penelitian ini bertujuan untuk memproduksi nori dari rumput laut U. lactuca dan E. cottonii dan menguji karakteristik mutu fisik, kimia dan sensori. Dari hasil penelitian didapatkan bahwa campuran rumput laut U. lactuta dan E. cottonii dapat menghasilkan produk nori yang berkualitas. Hasil uj i organoleptik menunj ukkan produk nori yang dipanggang lebih dapat diterima dibandingkan nori tidak dipanggang. Karakteristik kimia dan fisik produk berbeda nyata pada taraf 5%. Hasil analisis karakteristik kimia menunjukkan bahwa produk nori rumput laut U. lactuca dan E. cottonii mempunyai kandungan protein yang lebih rendah (18.84%), kandungan karbohidrat yang lebih tinggi (62.31%), kandungan serat pangan yang lebih tinggi (36.76%) dan kapasitas antioksidan yang lebih rendah (43.01%) dibandingkan nori komersial (karbohidrat 41.8%, protein 40%, serat 21.3%, kapasitas antioksidan 51%). Rumput laut di Indonesia saat ini digunakan sebagai penghasil agar, karaginan, dan alginat yang merupakan bahan baku penting dalam industri pangan maupun non pangan. Rumput laut Eucheuma cottonii yang banyak dibudidayakan di Indonesia dimanfaatkan untuk industri penghasil karaginan dan untuk produk pangan lainnya seperti untuk campuran es, dodol dan lain-lain. Rumput laut Ulva lactuca merupakan rumput laut yang tumbuh secara alami di perairan Indonesia, di mana pemanfaatannya masih sangat terbatas.
