Response of the obligate halophile fungus Aspergillus loretoensis to stress salinity

Fungi are recognized as indigenous microbes in natural hypersaline habitats. Aspergillus sp, among other fungi, is predominant those environments; however, their adaptative abilities recently studied. This study analyzes the transcriptomic response of an obligate halophile loretoensis under two salinity conditions (4% and 15% NaCl). fungus shows stress low NaCl concentration tested since it overexpresses genes like SOD2 (oxidative oxygen toxicity), ASG (resistance to salinity), transmembrane transport (ZRT2, OAC1, PMA1, ZRC1, SNQ2, MCH4, YO075, SIT1). Meanwhile, at NaCl, up-regulated were related osmolytes (STL1, HXT13, ZRT1), carbohydrate transport, metabolism (MAL11, PK1, ITR1), all suggesting adaptive conditions. expresses interesting metabolic enzymes with potential uses biotechnology invertases, isomerases, maltases, lipases. As well showed biosynthetic pathways oil degradation antibiotic production.
