Email this article Laurencia dendroidea, Ocumare of the Coast, Aragua state Venezuela: Evaluation of its Antimicrobial Effect and Phytochelatin Synthase-heavy Metal Balance
Abstract
In this work, the ability of Laurencia dendroidea to affect the growth of two strains of global interest was evaluated and how the algae can be very useful in environmental terms due to the contamination of the coasts by heavy metals. Regarding the results, it could be observed that for the entire concentration range there was inhibition of proliferation in both strains (Staphylococcus aureus and Klebsiella pneumoniae), however in K pneumoniae the effect was less marked, possibly attributed to the lipopolysaccharides.The activity of phytochelatin synthase, it was found that the sample obtained from point four of the studied area presented the highest activity, which is related to the concentration of metals. For the other sampled points, the values of heavy metals were within the range established by the National Metrology Institute of Japan. This study then allows us to establish that the use of algae for other purposes requires an exhaustive evaluation.
