摘要

台灣屬於海島型國家，為達到水資源有效利用而興建水庫，成為台灣飲用水主要來源。但因集水區內農業發展及廢水排放，造成台灣半數以上湖泊、水庫面臨嚴重優養化問題。倘能將優養化水體中天然產生之藻類適當收集，進而製成生質能，不僅具提供替代能源之價值，更可達淨化水質之附加效益。

本研究收集現地優養化藻類，經由適當的前處理(乾燥、破碎、研磨、過篩)後分為三組實驗，探討藻類生物質之經濟效益，以不同的水解條件探討糖化效果，並進一步分析水解產物之組成、水解副產物之影響及生質能源之效益，並分選出幾組最佳之水解條件做為後續發酵試驗參考之依據。藻類生物質於最佳的水解條件下，總還原糖萃取量可由86 mg reducing sugar/g algae提升至162.7 mg reducing sugar/g algae，表示收集優養化藻體供製生質能是具可行性與經濟性的。

The issue of water resources in Taiwan is facing a rigorous problem regarding eutrophication of lakes and reservoirs. It would be beneficial, if we can effectively collect the algae from eutrophication water bodies, to purify water quality and produce bioenergy.

This study collect the algae in lakes. The pretreated samples of dried algae were further divided into three groups. To examine the algae biomass for economic benefit. Further analysis the composition of the hydrolyzate , effect of hydrolysis byproducts and benefits the biomass energy. And choose of the optimal conditions groups to provide reference to fermentation. Algae biomass in the optimal hydrolysis conditions. its quantity of reducing sugar increase from 86 mg reducing sugar/g algae to 162.7 mg reducing sugar/g algae. Indicating that it is economically and practically feasible to collect algae in eutrophication water body for producing bioenergy.
