Abstract Ultrasonic-assisted extraction (UAE) is increasingly emerging as a highly effective technique. This technique affected by several experimental factors. The present work aimed to optimize the ultrasonic-assisted of antioxidants from Ulva lactuca (sea lettuce), widespread macroalgae growing along Mediterranean coast. In this respect, full-factorial design (2 3 ) was employed assess effec...

The green algal genus Ulva includes a speciose group of marine macroalgae inhabiting shallow seas worldwide. Although algal blooms in Asia highlight the opportunistic nature of several "nuisance" species, recent research clearly reveals important positive benefits of Ulva. Applied research requires accurate, reliable, and rapid identification, however, identification of Ulva spp. has met with c...

Nutrient input drive macroalgal blooms and increases in photosynthetic activity coastal ecosystems. An intense can increase the surrounding pH it could prevent acidification that often follows an eutrophication process. We tested this hypothesis with field sampling experiments a macrotidal (up to 9 m amplitude) system within semi-desert region contrasting eutrophic conditions Ulva lactuca north...

In recent years, plant growth promoting bacteria (PGPB) have been used as biofertilizers that increase agricultural productivity and resistance to changing environmental conditions such drought, salinity heat stress. One of the proposed new approaches productivity, especially under stress conditions, is using algae extracts, which usually consist naturally occurring bioactive compounds. Paeniba...

Specimens of Aplysia punctata inhabiting the Catalonian coast (NE Spain, Western Mediterranean Sea) display two different color patterns, which have been thought to represent distinct species. However, molecular analyses conducted by other authors and confirmed herein show that there are no genetic differences between individuals morphs. At same time, these morphs life history traits, including...
