Tracking dynamics of plant biomass composting by changes in substrate structure, microbial community, and enzyme activity
BACKGROUND Understanding the dynamics of the microbial communities that, along with their secreted enzymes, are involved in the natural process of biomass composting may hold the key to breaking the major bottleneck in biomass-to-biofuels conversion technology, which is the still-costly deconstruction of polymeric biomass carbohydrates to fermentable sugars.However, the complexity of both the s...
متن کاملMicrobial community composition and in silico predicted metabolic potential reflect biogeochemical gradients between distinct peatland types.
It is not well understood how the ecological status and microbial community composition of spruce swamp forests (SSF) relate to those found in bogs and fens. To clarify this, we investigated biogeochemical parameters and microbial community composition in a bog, a fen and two SSF using high throughput barcoded sequencing of the small ribosomal subunit (SSU) variable region V4. The results demon...
متن کاملPlant functional types define magnitude of drought response in peatland CO2 exchange.
Peatlands are important sinks for atmospheric carbon (C), yet the role of plant functional types (PFTs) for C sequestration under climatic perturbations is still unclear. A plant-removal experiment was used to study the importance of vascular PFTs for the net ecosystem CO2 exchange (NEE) during (i.e., resistance) and after (i.e., recovery) an experimental drought. The removal of PFTs caused a d...
متن کاملبررسی تاثیر چرای دام بر گروه های عملکردی گیاهان در منطقه بهارکیش قوچان (plant functional types)
چرای دامهای اهلی و خشکسالی در ایران، به عنوان مهمترین عوامل در تغییر و شکلگیری پوشش گیاهی مطرح هستند. عوامل زیستی و غیر زیستی باعث تغییرات قابل پیشبینی در صفات گیاهی در پیش- (plant functional types (pfts)) امتداد گرادیان محیطی میشوند. گروههای عملکردی گیاهی بینی تغییرات در فرایندهای اکوسیستم را مستقیماً از طریق تغییرات منعکس شده در ترکیب گونههای گیاهی در پاسخ به تغییرات محیطی امکانپذیر میکند....
15 صفحه اولDominant Tree Species and Soil Type Affect the Fungal Community Structure in a Boreal Peatland Forest.
Boreal peatlands play a crucial role in global carbon cycling, acting as an important carbon reservoir. However, little information is available on how peatland microbial communities are influenced by natural variability or human-induced disturbances. In this study, we have investigated the fungal diversity and community structure of both the organic soil layer and buried wood in boreal forest ...
