%X the chemical composition and some biological properties of four algae (ulva rigida, codium bursa, cystoseira barbata, and ceramium diaphanum) collected from the gabes gulf area (tunisia) were examined. ash (11.35-29.08% weight/dry weight [w/dw]) and total sugar (13.20-18.70% w/dw) were the most abundant contents in these algae. protein contents were moderate (5.03-14.00% w/dw), with the red alga (c diaphanum) having the highest value. lipid contents were within the range mentioned for seaweeds (<3% w/dw). saturated fatty acids occurring at the highest proportions were c16:0 (24.53-41.37%) and c12:0 (10.37-24.44%). the most abundant monounsaturated fatty acid was c18:1n-9 (21.74-54.22%), whereas the most abundant polyunsaturated fatty acid was c18:2n-6 (9.57-11.71%). variations in chemical composition can be attributed to both environmental and genetic differences among species. all algal extracts displayed antibacterial activity against escherichia coli and staphylococcus simulans (inhibition diameter: 10-25 mm), antioxidant activity (radical scavenging activity: 0.8-23%), and anti-inflammatory activity (48-61% inhibition of the phospholipase a2 activity); therefore, the marine algae examined can be considered abundant resources of bioactive molecules.
