“…These molecules have distinct features that meet the need of green industry applications [ 162 , 177 , 189 , 190 ]. In this view, psychrophilic and psychrotolerant fungi are specialized in producing extracellular and intracellular cold active-enzymes [ 20 , 189 , 191 ], which they use to live in harsh conditions to degrade molecules and for the uptake of nutrients [ 141 , 170 , 192 , 193 , 194 ]. Recently, these cold-adapted enzymes have attracted growing interest because of their potential benefits in several industrial fields [ 175 , 185 , 195 ].…”

The Antarctic Ocean is one of the most remote and inaccessible environments on our planet and hosts potentially high biodiversity, being largely unexplored and undescribed. Fungi have key functions and unique physiological and morphological adaptations even in extreme conditions, from shallow habitats to deep-sea sediments. Here, we summarized information on diversity, the ecological role, and biotechnological potential of marine fungi in the coldest biome on Earth. This review also discloses the importance of boosting research on Antarctic fungi as hidden treasures of biodiversity and bioactive molecules to better understand their role in marine ecosystem functioning and their applications in different biotechnological fields.

“…Enzymes such as lipase, esterase, glycosidase, protease and chitinase have huge potential to be used in a myriad of processes in the food, detergent, textiles and waste industries. Esterase enzymes play a major role in the degradation of natural materials and industrial pollutants, cereal wastes, plastics, and other toxic chemicals [89]. Hashim et al (2018) reported a new cold-active esterase-like protein with putative dienelactone hydrolase (GaDlh) function with an optimal temperature of 10 • C and an optimum pH of 8.0 using short-chain soluble esters as substrates.…”

“…Another subtilisin-like protease in G. antarctica (GaSUB) which is categorized under family S8 protease showed a low number of arginine residues, a high percentage of polar residues, less hydrophobic interactions and low glycine content [95]. Glucosidases also have a high potential to be used in food and beverage production, biological agent control, detergents, pharmaceuticals and paper manufacturing [89].…”

“…Given their proclivity for high activity at low temperatures and thermolability, cold-active enzymes/proteins are superior candidates for numerous industrial applications. Apart from its structural characteristics, cold-active enzymes/proteins trump their mesophilic counterparts as it minimizes energy usage and reduces the need for high temperature to activate the enzymes, thus leading to more economical and sustainable processes [ 89 ].…”

Psychrophilic organisms possess several adaptive strategies which allow them to sustain life at low temperatures between −20 to 20 °C. Studies on Antarctic psychrophiles are interesting due to the multiple stressors that exist on the permanently cold continent. These organisms produce, among other peculiarities, cold-active enzymes which not only have tremendous biotechnological potential but are valuable models for fundamental research into protein structure and function. Recent innovations in omics technologies such as genomics, transcriptomics, proteomics and metabolomics have contributed a remarkable perspective of the molecular basis underpinning the mechanisms of cold adaptation. This review critically discusses similar and different strategies of cold adaptation in the obligate psychrophilic yeast, Glaciozyma antarctica PI12 at the molecular (genome structure, proteins and enzymes, gene expression) and physiological (antifreeze proteins, membrane fluidity, stress-related proteins) levels. Our extensive studies on G. antarctica have revealed significant insights towards the innate capacity of- and the adaptation strategies employed by this psychrophilic yeast for life in the persistent cold. Furthermore, several cold-active enzymes and proteins with biotechnological potential are also discussed.

“…These properties make them a potentially valuable alternative to their mesophilic counterparts in cold environments. They may represent an interesting advantage in large scale processes, that generally occur at higher temperatures, for reducing the energy costs associated with heating steps [19][20][21]. While the thermosensitivity provides the possibility of rapidly inactivating them by mild heat treatments, preserving in this way the product quality [18].…”

Antarctica, one of the harshest environments in the world, has been successfully colonized by extremophilic, psychrophilic, and psychrotolerant microorganisms, facing a range of extreme conditions. Fungi are the most diverse taxon in the Antarctic ecosystems, including soils. Genetic adaptation to this environment results in the synthesis of a range of metabolites, with different functional roles in relation to the biotic and abiotic environmental factors, some of which with new biological properties of potential biotechnological interest. An overview on the production of cold-adapted enzymes and other bioactive secondary metabolites from filamentous fungi and yeasts isolated from Antarctic soils is here provided and considerations on their ecological significance are reported. A great number of researches have been carried out to date, based on cultural approaches. More recently, metagenomics approaches are expected to increase our knowledge on metabolic potential of these organisms, leading to the characterization of unculturable taxa. The search on fungi in Antarctica deserves to be improved, since it may represent a useful strategy for finding new metabolic pathways and, consequently, new bioactive compounds.
