“…Of note is the ability of all isolates to utilize a broad range of carbon sources. This may contribute to their phenotypic plasticity, being one of the reasons (dela Cruz et al , 2006) why these species can be found on varied substrates in different marine habitats and climate zones.…”

Carbon utilization by the marine Dendryphiella species, D. arenaria and D. salina, was investigated to detect differences in utilization and traits associated with their adaptation to the marine habitat. Fifty-four strains were isolated world-wide and tested for the utilization of various carbon sources using BIOLOG phenotype MicroArray (PM) and for the production of extracellular enzymes on solid culture media and on API ZYM assay strips. PM analysis showed that the fastest growth occurred on several monosaccharides and amino acids, 2-keto-d-gluconic acid, succinamide and turanose. Some polyols were poor carbon sources. However, the two species differed in their utilization rates of carbon sources, forming three major clusters: two separate clusters for D. arenaria and D. salina and a third cluster in which strains of the two species formed separate subclades that correlated with geographic origin. Several carbon sources were also found useful in differentiating the two speices. Dendryphiella salina did not utilize xylitol and quinic acid, whereas D. arenaria grew well on these substrates. The latter failed to grow on sorbitol and grew slowly on mannitol, both were good substrates for the former. There were also no qualitative differences between the extracellular enzymes produced, although laccase and peroxidase activities were confined only to some strains. The physiological similarities exhibited by the two species support the close relationship between D. arenaria and D. salina.

“…These marine-derived fungi (MDF) grow and possibly sporulate in the marine ecosystem (Kohlmeyer and Kohlmeyer 1979). Interestingly, many of these marine-derived fungi produce structurally diverse and bioactive compounds (dela Cruz et al 2006a, Schulz et al 2008, Silber et al 2016, utilized varied substrata (dela Cruz et al 2006b), and may play an important ecological role in marine habitats (Solis et al 2010). In spite of their economic and ecological importance, some of the less explored MDF thrive inside healthy tissues of macroalgae, e.g.…”

The occurrence and bioactivities of marine-derived fungi are evaluated in this paper. A total of 16 morphospecies of marine-derived fungi (MDF) were isolated from four host macroalgae and two seagrasses and identified as belonging to the genera Aspergillus, Fusarium, Paecilomyces, Penicillium, Sclerotinia, Thamnidium and Trichoderma, including five mycelia sterilia. Among these host organisms, the rhodophyte Laurencia intermedia harboured the highest number of isolated MDF. Selected MDF were then assayed and showed to inhibit Pseudomonas aeruginosa (8-19 mm zone of inhibition) and Staphylococcus aureus (6-19 mm zone of inhibition), and were cytotoxic against the brine shrimp Artemia salina nauplii (LD50: 201.56-948.37 μg mL−1). The screening led to the selection of five of the most bioactive morphospecies, all belonging to the genus Aspergillus. These marine aspergilli were subjected to β-tubulin gene sequence analysis for species identification, and to mass production in different culture media with or without marine salts, and screening of the crude culture extracts for their cytotoxic and trypanocidal activities. Aspergillus tubingensis cultivated in potato dextrose broth with marine salt proved to be the most cytotoxic against P388 (IC50: 1028 ng mL−1) and HeLa (IC50: 1301 ng mL−1) cancer cells. On the other hand, A. fumigatus cultivated in malt extract broth without marine salt was shown to be the most potent against Trypanosoma congolense (IC50: 298.18 ng mL−1). Our study therefore showed that salinity may influence the bioactivities of some species of MDF.

“…It is extremely widespread and has then been found in many ecosystems from the tropics to mid latitudes. It occurs in salt marshes, in sediments, at the surface of living or dead algae thalli [ 4 ], sea grasses and woods and has been successfully, isolated from various plant and algal substrates at different geographical locations and climatic zones ([ 5 , 6 ] and references therein).…”

Laminariales Host Does Impact Lipid Temperature Trajectories of the Fungal Endophyte Paradendryphiella salina (Sutherland.)

Kelps are colonized by a wide range of microbial symbionts. Among them, endophytic fungi remain poorly studied, but recent studies evidenced yet their high diversity and their central role in algal defense against various pathogens. Thus, studying the metabolic expressions of kelp endophytes under different conditions is important to have a better understanding of their impacts on host performance. In this context, fatty acid composition is essential to a given algae fitness and of interest to food web studies either to measure its nutritional quality or to infer about its contribution to consumers diets. In the present study, Paradendryphiella salina, a fungal endophyte was isolated from Saccharina latissima (L.) and Laminaria digitata (Hudson.) and its fatty acid composition was assessed at increasing salinity and temperature conditions. Results showed that fungal composition in terms of fatty acids displayed algal-dependent trajectories in response to temperature increase. This highlights that C18 unsaturated fatty acids are key components in the host-dependant acclimation of P. salina to salinity and temperature changes.
