“…or Nannochloropsis sp. with no recovery after few days [ 40 , 125 ] allows considering a bactericidal action of the extracellular substances produce by some microalgae [ 126 ]. Austin et al also observed a prompt inhibition of several Vibrio species by T. suecica in vitro and noticed a very rapid decrease in bacterial mobility with an elongation and vacuolisation of the cells in less than 20 min.…”

The search for novel compounds of marine origin has increased in the last decades for their application in various areas such as pharmaceutical, human or animal nutrition, cosmetics or bioenergy. In this context of blue technology development, microalgae are of particular interest due to their immense biodiversity and their relatively simple growth needs. In this review, we discuss about the promising use of microalgae and microalgal compounds as sources of natural antibiotics against human pathogens but also about their potential to limit microbial infections in aquaculture. An alternative to conventional antibiotics is needed as the microbial resistance to these drugs is increasing in humans and animals. Furthermore, using natural antibiotics for livestock could meet the consumer demand to avoid chemicals in food, would support a sustainable aquaculture and present the advantage of being environmentally friendly. Using natural and renewable microalgal compounds is still in its early days, but considering the important research development and rapid improvement in culture, extraction and purification processes, the valorization of microalgae will surely extend in the future.

“…We did not detect Vibrio in our fresh or refrigerated cultures, perhaps due to the high quality of the cultures and the antibacterial characteristics of S. elongatus and C. muelleri (Sánchez-Saavedra et al, 2010). Consequently, S. elongatus can provide additional benefits by reducing bacterial load (González-Davis et al, 2012;Molina-Cárdenas et al, 2014).…”

ABSTRACT. The aim of this study was to evaluate the performance of the cyanobacterium Synechococcus elongatus after refrigerated storage (4°C) and examine its potential as food for Artemia franciscana. Non-axenic semicontinuous cultures of S. elongatus were maintained at 4°C for 8 weeks. In our bioassay, we fed A. franciscana with refrigerated S. elongatus and fresh cultures of the diatom Chaetoceros muelleri as a control. The S. elongatus cultures could be refrigerated for up to 8 weeks without loss of its viability or alteration in its growth rate, cell size, and proximate composition. Fresh and eight week-refrigerated cultures of S. elongatus were similar with regard to fatty acid profiles. Significant differences in fatty acid profiles were found between refrigerated S. elongatus and fresh C. muelleri cultures. Vibrio bacteria were not detected in any of the S. elongatus cultures (fresh or refrigerated) or fresh cultures C. muelleri. This work demonstrated that refrigerated S. elongatus can be used to feed A. franciscana, maintaining similar growth rates and proximate composition compared with fresh C. muelleri cultures as feed. Thus, S. elongatus has potential aquaculture use as feed for A. franciscana.
