Indonesia, especially in the Riau Islands has abundant marine biological natural resources. So that it can be used as basic ingredient of a search for medicinal or materials. One them is caulerpa racemosa sea grape type from green algae group which contains variety secondary metabolites with bioactive compounds are cytotoxic to kill cancer cells. This study aims determine activity ethanol extra...

nvestigations on indigenous and non-indigenous invasive flora fauna of a certain geographical area are always important to assess their impact native biodiversity control spread by making conservation strategies protect biodiversity. In this study, we have encountered overwhelming growth six seaweed species, Caulerpa racemosa, C. serrulata, sertularioides, taxifolia, peltata, Halimeda opuntia t...

BACKGROUND Three species of seaweeds (Padina tetrastromatica, Caulerpa racemosa and Turbinaria ornata) are widely consumed by Asians as nutraceutical food due to their antioxidant properties. Studies have shown that these seaweeds exhibit bioactivities which include antimicrobial, antiviral, anti-hypertensive and anticoagulant activities. However, investigations into the mechanisms of action pe...

Sea grape (Caulerpa racemosa) is an edible green alga which contains a high amount of protein with seafood flavor, can be released via hydrolysis. Our present work was designed to determine the optimal concentration palm sugar and carboxymethylcellulose (CMC) in sea hydrolysate sauce. The process optimization performed evaluate multiple parameters such as viscosity, color properties, hedonic sc...

Behavioural interactions between ecosystem engineers may strongly influence community structure. We tested whether an invasive ecosystem engineer, the alga Caulerpa taxifolia, indirectly facilitated community diversity by modifying the behaviour of a native ecosystem engineer, the clam Anadara trapezia, in southeastern Australia. In this study, clams in Caulerpa-invaded sediments partially unbu...
