Abstract
In the development of medicinally important Orchidaceae, the extent of fungal endophytes specificity is not presently very clear. Limited study has been available on natural products formed and its role on plant growth, defence mechanism by endophytes, and to characterize the chief treasure of bioactive molecules. Therefore, this review article presents an evaluation of the endophytes associated with Orchidaceae for physiology, metabolism, and genomics which have prominently contributed to the resurgence of novel metabolite research increasing our considerate of multifaceted mechanisms regulatory appearance of biosynthetic gene groups encoding diverse metabolites. Additionally, we presented the comprehensive recent development of bio-strategies for the cultivation of endophytes from Orchidaceae and integration of bioengineered ‘Genomics with metabolism’ approaches with emphases collective omics as powerful approach to discover novel metabolite compounds. The Orchidaceae-fungal endophytes' biodynamics for sustainable development of bioproducts and its applications are supported in large-scale biosynthesis of industrially and pharmaceutical important biomolecules.

Abstract
Fungi from extreme environments, including acidophilic ones, belong to biotechnologically most attractive organisms. They can serve as a source of enzymes and metabolites with potentially uncommon properties and may actively participate within bioremediation processes. In respect of their biotechnological potential, extremophilic fungi are mostly studied as individual species. Nevertheless, microorganisms rarely live separately and they form biofilms instead. Living in biofilms is the most successful life strategy on the Earth and the biofilm is the most abundant form of life in extreme environments including highly acidic ones. Compared to bacterial fraction, fungal part of acidophilic biofilms represents a largely unexplored source of organisms with possible use in biotechnology and especially data on biofilms of highly acidic soils are missing. The functioning of the biofilm results from interactions between organisms whose metabolic capabilities are efficiently combined. When we look on acidophilic fungi and their biotechnological potential we should take this fact into account as well. The practical problem to be resolved in connection with extensive studies of exploitable properties and abilities of acidophilic fungi is the methodology of isolation of strains from the nature. In this respect, novel isolation techniques should be developed.

Abstract
Soda saline-alkaline lands are significantly harmful to agriculture; thus, effective strategies to remediate such soil are urgently needed. Multiple negative factors exist in the community structure of saline-alkaline fields, among which the lack of fungal species diversity remains the most prominent problem. The haloalkaliphilic fungi are a unique group of extremophiles that grow optimally under conditions of extreme salinity and alkalinity; these fungi, which buffer salinity and alkalinity by absorbing and/or constraining salt ions, produce organic acids and/or macromolecules, secrete macromolecules such as cellulose degradation enzymes, and provide biomass that is beneficial for soil health. Considering that haloalkaliphilic fungi are a valuable genetic resource of resistance and degradation genes, these fungi are expected to be applied in biotechnology. Aspergillus glaucus exhibits high resistance to a variety of stressors and the ability to degrade crop straw; and it is a practical genetic tool that can be used to identify and validate genes involved in abiotic stress resistance and cellulose decomposition genes. This review will focus on the following aspects: isolation of extreme haloalkaliphilic fungi, fungal genes involved in salt and alkalinity resistance, macromolecule degrading enzymes, applications for genetic improvement of haloalkaliphilic fungi, and application of haloalkaliphilic fungi in saline-alkali soil mycoremediation.

Abstract
Technosols or technogenic substrates contaminated by potentially toxic elements as a result of iron mining causes not only contamination of the surrounding ecosystem but may also lead to changes of the extent, abundance, structure and activity of soil microbial community. Microbial biomass were significantly inhibited mainly by exceeding limits of potentially toxic metals as arsenic (in the range of 343-511 mg/kg), copper (in the range of 7980-9227 mg/kg), manganese (in the range of 2417-2670 mg/kg), alkaline and strong alkaline pH conditions and minimal contents of organic nutrients. All of the 14 bacterial isolates, belonged to 4 bacterial phyla, Actinobacteria, Firmicutes; β- and γ-Proteobacteria. Thirteen genera and 20 species of microscopic filamentous fungi were recovered. The most frequently found species belonged to genera Aspergillus (A. clavatus, A. niger, A. flavus, A. versicolor, Aspergillus sp.) with the dominating A. niger in all samples, and Penicillium (P. canescens, P. chrysogenum, P. spinulosum, Penicillium sp.). Fungal plant pathogens occurred in all surface samples. These included Bjerkandera adustata, Bionectria ochloleuca with anamorph state Clonostachys pseudochloleuca, Lewia infectoria, Phoma macrostoma and Rhizoctonia sp.

Abstract
Intact, growing cells of strongly acidophilic fungi Acidea extrema and Acidothrix acidophila have been successfully transformed by introduction of heterologous DNA fragment (composed of the glyceraldehyde-phosphate-dehydrogenase gene promoter from Emericella nidulans, a metallothionein-coding gene AsMt1 from Amanita strobiliformis and glyceraldehyde-phosphate-dehydrogenase gene terminator from Colletotrichum gloeosporioides) with the length of 1690 bp. The transformation procedure was based on the DNA transfer mediated by Agrobacterium tumefaciens bearing disarmed helper plasmid pMP90 and binary vector pCambia1300 with inserted DNA fragment of interest. The transformants proved to be mitotically stable, and the introduced gene was expressed at least at the level of transcription. Our work confirms that metabolic adaptations of strongly acidophilic fungi do not represent an obstacle for genetic transformation using conventional methods and can be potentially used for production of heterologous proteins. A promising role of the fast growing A. acidophila as active biomass in biotechnological processes is suggested not only by the low susceptibility of the culture grown at low pH to contaminations but also by reduced risk of accidental leaks of genetically modified microorganisms into the environment because highly specialized extremophilic fungi can poorly compete with common microflora under moderate conditions.
