“…Owing to restricted access of ligninolytic enzymes to lignin granules which are deposited on the surface of lignocellulosic fibres, pressure refining was applied for separation of fibres of lignocellulosic materials. This strategy enhanced the accessibility of ligninolytic enzymes from white-rot fungus Ceriporiopsis subvermispora which showed higher delignification from pressure refined Miscanthus than milled Miscanthus [21]. Extracellular ligninolytic enzymes also have capacity for adsorption of dyes which has made white-rot fungi, a dominating force in the area of dye degradation or decolourization as demonstrated in case of decolorization of Direct Blue 14 by various species of Pleurotus [22] and Remazol Brilliant Blue-R by Agaricomycete, a white-rot fungus from Amazon forest [23].…”

Bioremediation refers to cost-effective and environment-friendly method for converting the toxic, recalcitrant pollutants into environmentally benign products through the action of various biological treatments. Fungi play a major role in bioremediation owing to their robust morphology and diverse metabolic capacity. The review focuses on different fungal groups from a variety of habitats with their role in bioremediation of different toxic and recalcitrant compounds; persistent organic pollutants, textile dyes, effluents from textile, bleached kraft pulp, leather tanning industries, petroleum, polyaromatic hydrocarbons, pharmaceuticals and personal care products, and pesticides. Bioremediation of toxic organics by fungi is the most sustainable and green route for cleanup of contaminated sites and we discuss the multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, laccases, peroxidases and cyrochrome P450 monooxygeneses. We have also discussed the recent advances in enzyme engineering and genomics and research being carried out to trace the less understood bioremediation pathways.

“…Это может быть связано с различиями в их фосфолипидном составе [51]. Более того, сферические ЛПВП эффективнее, чем дисковидные, что подчеркивает важность формы частиц в противовоспалитель-ной активности [51,52]. Следует отметить, что отдельные фрак-ции частиц, находящиеся среди маленьких плотных ЛПВП, об-ладают иммуномодулирующей способностью по отношению к нейтрофилам; в этих частицах количественно преобладает фак-тор H-родственных белков [53].…”

Г.В. Плеханова» Минобрнауки россии, Москва, россия Аннотация Увеличение концентрации липопротеидов высокой плотности (лПВП) в плазме крови человека может являться частью стратегии борьбы с сердечно-сосудистыми заболеваниями (ССз). частицы лПВП неоднородны по структуре, метаболизму и биологической активности. В обзоре описаны основные фракции (субпопуляции) лПВП и обсуждаются новые данные об антиатерогенных свойствах частиц лПВП. Весь спектр фракций лПВП, маленьких плотных богатых белком липопро-теидов, обладает атеропротективными свойствами, которые определяются наличием специализированных групп белков и липидов, однако такая активность может быть понижена в условиях атерогенного поражения. Всесторонний структурный и композиционный анализ лПВП позволяет обеспечить ключевую информацию для выявления фракций, обладающих характерными биологическими свойствами и теряющих функциональность при ССз. Эти фракции также могут являться биомаркерами риска развития ССз и как следствие фармакологическими мишенями. Increasing the human plasma concentration of high-density lipoproteins (hDL) may be part of strategy for control of cardiovascular diseases (cVD). hDL particles vary in their structure, metabolism, and biological activity. The review describes major hDL fractions (subpopulations) and discusses new findings on the antiatherogenic properties of hDL particles. The whole spectrum of hDL fractions, small, dense, protein-rich lipoproteins, has atheroprotective properties that are determined by the presence of specialized groups of proteins and lipids; however, this activity may be decreased in atherogenic lesion. comprehensive structural and compositional analysis of hDL may provide key information to identify the fractions that have characteristic biological properties and lose their functionality in cVD. These fractions may be also biomarkers for the risk of cVD and hence represent pharmacological targets.

“…In another study, fungi associated with M. x giganteus were isolated, and studies of its degradation showed that some Ascomycota were principally involved, although it was concluded that they were unlikely to be as effective as white rot fungi under suitable conditions (Shrestha et al 2011). A recent study using three white rot fungi revealed that growth occurred causing changes in the fibrous composition that varied depending on the fungus (Baker et al 2015).…”

a Miscanthus, which is comprised of several different genotypes, is an important high-biomass crop with applications in the biofuel industry and in the formation of biocomposite materials. The overall composition of Miscanthus can be altered via degradation with wood rot fungi. The starting composition revealed that the cellulose content of Miscanthus x giganteus was higher than that in Miscanthus sacchariflorus and that the lignin contents were similar in both genotypes. Of the wood rot fungi, only Lentinus edodes appeared to have completely colonized M. sacchariflorus and showed significant degradation. In contrast, all of the brown rot fungi showed partial colonization of both Miscanthus genotypes and had little effect on the fibrous composition. Cellulose degradation by some white rot fungi increased with cellulose content whereas cellulose degradation by other fungi was independent of cellulose content. All of the white rot fungi showed similar rates of lignin degradation, except for Pleurotus ostreatus, which was higher on M. sacchariflorus. The effect of the moisture contents of Miscanthus on cellulose and lignin decomposition by Phlebiopsis gigantea SPLog6 and Coniophora puteana 11E was also investigated. These results revealed subtle differences in the growth of white rot fungi on different Miscanthus genotypes.
