Journal Article

Comparative molecular dynamics simulations provided insights into the mechanisms of cold-adaption of alginate lyases from the PL7 family

Bian, Fei; Liang, Xiao-Yue; Wang, Meng; Sun, Zhong-Zhi; Xie, Bin-Bin

2024 Extremophiles

doi:10.1007/s00792-024-01340-8 pmid:38598094

Alginate is an important polysaccharide that is abundant in the marine environments, including the Polar Regions, and bacterial alginate lyases play key roles in its degradation. Many reported alginate lyases show characteristics of cold-adapted enzymes, including relatively low temperature...

Antarctic marine sediment as a source of filamentous fungi-derived antimicrobial and antitumor compounds of pharmaceutical interest

Camacho, Karine Fernandes; de Melo Carlos, Layssa; Bernal, Suzan Prado Fernandes; de Oliveira, Valéria M.; Ruiz, Jorge Luiz Maria; Ottoni, Júlia Ronzella; Vieira, Rosemary; Neto, Arthur; Rosa, Luiz Henrique; Passarini, Michel Rodrigo Zambrano

doi:10.1007/s00792-024-01339-1 pmid:38532228

Antarctica harbors a microbial diversity still poorly explored and of inestimable biotechnological value. Cold-adapted microorganisms can produce a diverse range of metabolites stable at low temperatures, making these compounds industrially interesting for biotechnological use. The present work...

Fungal diversity present in snow sampled in summer in the north-west Antarctic Peninsula and the South Shetland Islands, Maritime Antarctica, assessed using metabarcoding

de Menezes, Graciéle Cunha Alves; Lopes, Fabyano A. C.; Santos, Karita C. R.; Silva, Micheline C.; Convey, Peter; Câmara, Paulo E. A. S.; Rosa, Luiz H.

2024 Extremophiles

doi:10.1007/s00792-024-01338-2 pmid:38575688

We assessed the fungal diversity present in snow sampled during summer in the north-west Antarctic Peninsula and the South Shetland Islands, maritime Antarctica using a metabarcoding approach. A total of 586,693 fungal DNA reads were obtained and assigned to 203 amplicon sequence variants (ASVs)....

Astrobiological implications of the organic and inorganic cyanide utilization by a novel Antarctic hyperthermophilic Pyrococcus strain

Uribe-Redlich, Patricio A.; Amenabar, Maximiliano J.; Dennett, Geraldine V.; Blamey, Jenny M.

2024 Extremophiles

doi:10.1007/s00792-024-01335-5 pmid:38427139

Organic and inorganic cyanides are widely distributed in nature, yet not much is known about the ability of microorganisms to use these compounds as a source of nitrogen and/or carbon at high temperatures (>80 °C). Here we studied the capacity of organic and inorganic cyanides to support growth...

Genome-based classification of the family Haloferacaceae and description of five novel species of Halobaculum

Tan, Shun; Zhu, Ling-Rui; Zhang, Qing-Ke; Dong, Xin-Yue; Hou, Jing; Cui, Heng-Lin

2024 Extremophiles

doi:10.1007/s00792-024-01337-3 pmid:38546878

The taxonomic status of some species of Halobellus, Haloferax, Halogranum, and Haloplanus within the family Haloferacaceae was elucidated by phylogenetic, phylogenomic, and comparative genomic analyses. The relative species of each genus should constitute a single species based on the overall...

Diversity and enzymatic, biosurfactant and phytotoxic activities of culturable Ascomycota fungi present in marine sediments obtained near the South Shetland Islands, maritime Antarctica

da Silva, Mayanne Karla; Barreto, Débora Luiza Costa; Vieira, Rosemary; Neto, Arthur Ayres; de Oliveira, Fábio Soares; Convey, Peter; Rosa, Carlos Augusto; Duarte, Alysson Wagner Fernandes; Rosa, Luiz Henrique

2024 Extremophiles

doi:10.1007/s00792-024-01336-4 pmid:38493412

We studied the culturable fungal community recovered from deep marine sediments in the maritime Antarctic, and assessed their capabilities to produce exoenzymes, emulsifiers and metabolites with phytotoxic activity. Sixty-eight Ascomycota fungal isolates were recovered and identified. The most...
