海洋植物逆境分子生理生態 😍 一扇通往海藻的門
本研究室了解海洋植物(大型藻類與微藻)如何透過代謝調控提升其對環境壓力的耐受性，適應氣候變遷的挑戰，特別關注藻類在二氧化碳捕集與永續廢棄物處理的雙重功能，將富含營養的廢水轉化為具經濟價值的生物產品，發展藻類為核心的碳封存技術、資源循環策略與具永續性的循環生物經濟系統。
我們實驗室也致力於探討海岸生態系統如何透過「藍碳系統」實現長期碳儲存，這些系統包括紅樹林、鹽沼與海草床。雖然這些生態系已廣為人知能有效封存有機碳，但其中許多碳實際上可能來自其他外源來源。其中一個關鍵且經常被忽略的貢獻者是大型海藻及極端氣候降雨沖出之陸生植物。由於其具有高生長速率、易碎片化以及能在不同生態系間傳輸的能力，大型海藻有潛力成為藍碳匯的重要碳供體。為了進一步瞭解大型海藻組織的穩定性及其參與長期碳封存的潛力，我們運用環境DNA（eDNA）、碳氮穩定同位素分析，以及熱重分析（TGA），來評估各類海洋大型海藻與海岸植物的碳穩定性。

Marine Plant Stress Molecular Physiology and Ecology: 😍A Gateway to Marine Algae
Our laboratory explores how microalgae and macroalgae enhance stress resilience through metabolic regulation, enabling adaptation to climate-induced challenges. We focus on their dual role in CO₂ capture and sustainable waste treatment, transforming nutrient-rich effluents into valuable bioproducts. This research supports the use of algae-based solutions for carbon sequestration, resource recycling, and the development of a circular bioeconomy.
Our lab also explores how coastal ecosystems contribute to long-term carbon storage through what are known as “blue carbon” systems, including mangroves, salt marshes, and seagrasses. While these habitats are well-known for their ability to sequester organic carbon, much of that carbon may come from outside sources. One key, yet often overlooked, contributor is the blooming of macroalgae due to anthropogenic activities and runoff from terrestrial plant detritus caused by heavy precipitation resulting from climate change. With their high growth rates, tendency to fragment, and capacity for transport across ecosystems, macroalgae can play a significant role in supplying carbon to these blue carbon sinks. To better understand how stable macroalgal tissues are—and how likely they are to contribute to long-term carbon storage—we use eDNA, isotope C and N, and thermogravimetric analysis (TGA) to assess carbon stability across a range of marine macroalgae and coastal plant species.

AbstractAquaculture waste and carbon dioxide (CO2) are a global concern. Sarcodia suae cultivated in outdoor photobioreactors (PBRs) using shrimp aquaculture wastewater and CO2 from biogas demonstrates significant benefits. It boosted biomass by 18.72% with nearly 100% removal of COD, inorganic nitrogen (N), phosphorus (P), and 41-89% organic N and P removal from AWW. Sarcodia aqueous extracts were biostimulants for promoting mung bean and rice seedling growth, and Sarcodia remnants/shrimp pond bottom sludge generated a biogas yield of 457.07 L/kg-VS methane (CH4)/day. Biogas provides renewable energy for the system's needs. The solid residues after biogas fermentation serve as biofertilizers for enhancing rice yield by a 15% increase up to 5.53 tons/ha/year. A Zero-Waste approach is successfully established using S. suiae as a model for recirculating aquaculture wastes to sequester 239.04 tons CO2/ha/year, capture N and sulfur (S), and produce renewable energy. and create biostimulants and biofertilizers.
