Biomass holds the potential to replace fossil-derived products with biofuels and bio-based chemicals. Plant-derived lipids are promising sources of biofuels; however, the production of plant oil often leads to the release of massive amounts of carbon dioxide due to deforestation and land-use change. The production of biofuels via plant oils (such as soybean) also competes with food production and in turn, impacts biodiversity. To mitigate these issues, the production of lipids from oleaginous yeasts could be an excellent alternative by incorporating these microbes into biorefineries utilizing agricultural or forest residues. Eventually, these microbial lipids could be potential sources for producing lipid-derived biofuels. However, the current conventional methods for the production and recovery of lipids from oleaginous microbes suffer from economic and ecological challenges that affect its industrial-scale expansion.

To understand how maize production influences soil carbon (C) dynamics, and whether this is influenced by soil type, we measured net ecosystem exchange (NEE) using the eddy covariance technique over the 2021 growing season. We combined the NEE data with C imports and exports to calculate the net ecosystem productivity (NEP) of two maize crops grown for bioenergy in the United Kingdom, one site on mineral soil and the other on lowland agricultural peat. Maize was similarly productive at both sites—gross primary productivity was 1107 g C m⁻² at the site with mineral soil and 1407 g C m⁻² at the peat site. However, total ecosystem respiration was considerably higher from the peat site (1198 g C m⁻²) compared with the mineral soil site (678 g C m⁻²). After accounting for the removal of C in harvested biomass, both sites were net C sources, but C losses were over two times greater from the peat site (NEP = 290 g C m⁻²) than the mineral site (NEP = 136 g C m⁻²). While annual crops may be needed to produce bioenergy in the short term, growing maize for bioenergy in the United Kingdom does not appear to be a viable option for C sequestration over the long term, as it leads to high carbon losses from agroecosystems, especially those on organic soils. Instead, growing perennial bioenergy crops on mineral soils with a low organic C content is a more appropriate option.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"16 7","pages":""},"PeriodicalIF":5.6,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.13169","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141329376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In some plant species, however, high heterozygosity and complex genome structure mean that researchers must use care in handling GBS data to conduct QTL mapping most effectively. Such outbred crops include most of the perennial grass and tree species used for bioenergy. To identify strategies for increasing accuracy and precision of QTL mapping using GBS data in outbred crops, we conducted an empirical study of SNP-calling and genetic map-building pipeline parameters in a <i>Miscanthus sinensis</i> population, and a complementary simulation study to estimate the relationship between genome-wide error rate, read depth, and marker number. The bioenergy grass <i>Miscanthus</i> is an obligate outcrossing species with a recent (diploidized) whole-genome duplication. For the study of empirical <i>M. sinensis</i> data, we compared two SNP-calling methods (one non-reference-based and one reference-based), a series of depth filters (12×, 20×, 30×, and 40×) and two map-construction methods (i.e., marker ordering: linkage-only and order-corrected based on a reference genome). We found that correcting the order of markers on a linkage map by using a high-quality reference genome improved QTL precision (shorter confidence intervals). For typical GBS datasets of between 1000 and 5000 markers to build a genetic map for biparental populations, a depth filter set at 30× to 40× applied to outbred populations provided a genome-wide genotype-calling error rate of less than 1%, improved accuracy of QTL point estimates and minimized type I errors for identifying QTL.

To avoid the problem of competition with food production, the use of abandoned agricultural land (AAL) for production of the feedstock for biofuel has been proposed. AAL has generally low productivity but has also low opportunity costs, and production of perennial bioenergy crops on it can lead to carbon sequestration. A spatially explicit optimization model of biofuel production and transport fuel consumption, applied to Sweden, was used for an analysis of how AAL can alter costs for greenhouse gas emissions abatement. Results show that, compared to the case without AAL, AAL could decrease the costs of reducing greenhouse gas emissions by 29%, for emissions reductions equivalent to 50% of current emissions from gasoline in Sweden. The carbon sequestration from establishing perennial bioenergy crops on AAL is the main driver of the positive results. High carbon sequestration on AAL implies larger emissions reduction for a given volume of biofuel, and the results show that the total biofuel production can be both smaller and larger with AAL. The use of arable land for biofuel production is generally smaller with AAL, but larger at some of the highest analyzed target levels. The low AAL feedstock costs contribute to lower costs of the total biofuel production, which pushes for more total biofuel production and less fuel use reduction and therefore counteracts the reduced use of arable land.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"16 7","pages":""},"PeriodicalIF":5.6,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.13165","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141245609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing sugar conversion process of <i>S. japonica</i> has been investigated by focusing on enzymatic or acid-catalyzed hydrolysis, but not hot water extraction although mannitol can be easily recovered using water. The effect of temperature (60–120°C) on the mannitol yield from <i>S. japonica</i> was investigated, and a mannitol yield of 208 g/kg biomass was achieved at the optimal temperature of 100°C (about 78% of the theoretical maximum yield). This study emphasizes that this simple process has considerable potential for application as over 80% of the fermentable carbohydrates in <i>S. japonica</i> were mannitol.
