“…Table 3 and Figure 1 show that the high keratinase activity as a clear zone around the colony (54, 65, 50, 58 and 60 mm) ( 25,18,20,25,15,23 and 21 mm), respectively. While Alternaria alternate and Curvularia lunata had negative keratinase activity The results agree to some extend with previous findings (Anbu et al, 2008;Awasthi and Kushwaha, 2011;Ramakrishnaiah et al, 2013;Kumar and Kushwaha, 2014;Singh, 2014;Singh et al, 2016;Bohacz, 2017).…”

The objective of this study was to evaluate the occurrence of mycoflora in 30 samples of healthy goat's hair and sheep wool collected from different localities in Taif, Saudi Arabia, and the ability of some fungal isolates for keratinase activities. Sixty four species belonging to 28 genera were collected from the two substrates. The wool of sheep was polluted with fungi than goat hairs, and contained high total counts and number of fungal genera and species. Nine species of true dermatophytes isolated belonged to Microsporum (3 species) and Trichophyton (6 species). Several keratinophilic species were isolated of which, Chrysosporium indicum, Chrysosporium keratinophilum and Chrysosporium tropicum were the most prevalent. The commonest saprophytes in order of frequency were members of the genera, Aspergillus, Penicillium, Alternaria and Cochliobolus. In addition, the other genera found included Acremonium, Chaetomum, Cladosporium, Cochliobolus, Fusarium, Mucor, Paecilomyces, Phoma, Rhizopus, Scopulariopsis, Stachybotrys, Trichoderma and others. Five species from 20 tested isolates (Aspergillus niger, C. keratinophilum, C. tropicum, Microsporum gypseum and Trichoderma viride) had high keratinase activity. The results of this study indicate that both goat hair and sheep wool provide a suitable habitat for dermatophytes and other keratinophilic fungi. Most of these fungi play an important role in the degradation of keratin substrates, so that they can help preserve the environment and reduce pollution.

“…Second, the small size (~2-10 μm diameter) of conidia is not limiting for dispersal and consequently should be distributed widely (Finlay 2002). In addition, both physical, such as advection (Hovmøller et al 2008) and biological phenomena, such as the movement of fungal propagules by animals (Singh et al 2016) aid in the wide-distribution of both marine and terrestrial fungi throughout the marine realm. Moreover, the evolved fungal appendages that aid in flotation and adhesion to substrate (Hyde et al 1993, Jones 1994, coupled with the known association of fungi with marine driftwood (Rämä et al 2016), suggests another mechanism for long-distance dispersal in the marine realm that could help eliminate detectable biogeography.…”

Growing interest in understanding the relevance of marine fungi to food webs, biogeochemical cycling, and biological patterns necessitates establishing a context for interpreting future findings. To help establish this context, we summarize the diversity of cultured and observed marine planktonic fungi from across the world. While exploring this diversity, we discovered that only half of the known marine fungal species have a publicly available DNA locus, which we hypothesize will likely hinder accurate highthroughput sequencing classification in the future, as it does currently. Still, we reprocessed >600 high-throughput datasets and analyzed 4.9 × 10 9 sequences (4.8 × 10 9 shotgun metagenomic reads and 1.0 × 10 8 amplicon sequences) and found that every fungal phylum is represented in the global marine planktonic mycobiome; however, this mycobiome is generally predominated by three phyla: the Ascomycota, Basidiomycota, and Chytridiomycota. We hypothesize that these three clades are the most abundant due to a combination of evolutionary histories, as well as physical processes that aid in their dispersal. We found that environments with atypical salinity regimes (>5 standard deviations from the global mean: Red Sea, Baltic Sea, sea ice) hosted higher proportions of the Chytridiomycota, relative to open oceans that are dominated by Dikarya. The Baltic Sea and Mediterranean Sea had the highest fungal richness of all areas explored. An analysis of similarity identified significant differences between oceanographic regions. There were no latitudinal gradients of marine fungal richness and diversity observed. As more high-throughput sequencing data become available, expanding the collection of reference loci and genomes will be essential to understanding the ecology of marine fungi.

“…14.1). The detection of fungi on Arctic marine bird feathers (Singh et al 2016) and in association with driftwood (Rämä et al 2014) suggests additional ecological niches occupied by the fungi that currently remain unexplored. Arctic members of the Labyrinthulomycota can exceed 10 5 cells L −1 (Naganuma et al 2006) and are capable of degrading pine pollen (Hassett and Gradinger 2018), suggesting that these organisms might be seasonally important in degradative processes.…”

Sea ice seasonally covers 10% of the earth's oceans and shapes global ocean chemistry. The unique physical processes associated with sea ice growth and development shape the associated biological diversity and ecosystem function. Microbes make up the base of all marine food webs and the overwhelming majority of biomass in the sea ice ecosystem. Despite their biomass, microbial processes are not fully integrated into marine ecosystem models. Recent applications of novel molecular biology technologies to studies of marine ecology have elucidated numerous microbial-mediated processes interfaced by previously unknown organisms and processes. These discoveries are yielding more in-depth studies on the relevance of mixotrophy, the ecology of fungi, and the interplay between major microbial clades. In ecosystem studies, the basis of the food web is frequently neglected even though the accessibility of energy, recycling of nutrients, and parasitism are crucial factors shaping the environment for grazers and higher trophic levels. In this review, we focus on the species composition, abundance, and functions of microalgae, bacteria, archaea, fungi, and viruses in the sea ice-covered seas throughout the year. A strong emphasis will be put on advances in molecular methods that empower scientists to further investigate microorganisms in more detail. Since microbes make up the majority of all oceanic biomass, we believe that it is impossible to accurately forecast the biological fate of polar marine ecosystems without placing a proportional emphasis on microbes relative to their biomass.
