Marine fungal biodiversity as a new precursor of biotechnology products is poorly studied compared to its terrestrial counterpart which has been used as a rich source of bioactive compounds. Because of the importance of marine fungi, we present here the first marine cultivable fungal isolates from sea sediments of 43 to 311 m depth from the Southern California Gulf, Mexico. Seventeen selected halotolerant fungi were isolated and identified by sequencing their ITS 1 and 2 genes. They belong to the phylum Ascomycota and Basidiomycota (16 and 1 isolates). Cladosporium spp were represented by 29%, Aspergillus spp by 24%, Talaromyces spp by 12% and other species by 35%. Two fungi showed antibacterial activity against E. coli and S. aureus.

A low-level-intensity magnetic field detection system has been designed and developed based on the amplification-selection process of signals. This configuration is also very sensitive to magnetic field changes produced by harmonic-like electrical currents transported in finite-length wires. Experimental and theoretical results of magnetic fields detection as low as 10−9T at 120Hz are also presented with an accuracy of around 13%. The assembled equipment is designed to measure an electromotive force induced in a free-magnetic-core coil in order to recover signals which are previously selected, despite the fact that their intensities are much lower than the environment electromagnetic radiation. The prototype has a signal-to-noise ratio of 60dB. This system also presents the advantage for using it as a portable unit of measurement. The concept and prototype may be applied, for example, as a nondestructive method to analyze any corrosion formation in metallic oil pipelines which are subjected to cathodic protection.

The complete mitochondrial genome of the fine flounder Paralichthys adspersus , was determined for the first time through Next Generation Sequencing (NGS) approach. The mitogenome (GenBank accession no. MW288827) has 17,060 bp in length and consisted of the well-known 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and the control region. The overall nucleotide composition of the whole mitogenome was A: 27.5%, C: 29.5%, G: 17.1%, and T: 25.9%. Phylogenetic analyses based on 12 protein-coding genes clustered P. adspersus in the monophyletic Paralichthyidae clade, showing the closest phylogenetic relationship with its congeneric species P . olivaceus .
