Multiomics dissection of Brassica napus L. lateral roots and endophytes interactions under phosphorus starvation.

Many plants associate with endophytic microbes that improve root phosphorus (P) uptake. Understanding the interactions between roots and endophytes can enable efforts to improve P utilization. Here, we characterize the interactions between lateral roots of endophytes in a core collection of 50 rapeseed (Brassica napus L.

Majorbio Cloud: A one-stop, comprehensive bioinformatic platform for multiomics analyses.

The platform consists of three modules, which are pre-configured bioinformatic pipelines, cloud toolsets, and online omics' courses. The pre-configured bioinformatic pipelines not only combine analytic tools for metagenomics, genomes, transcriptome, proteomics and metabolomics, but also provide users with powerful and convenient interactive analysis reports, which allow them to analyze and mine data independently. As a useful supplement to the bioinformatics pipelines, a wide range of cloud toolsets can further meet the needs of users for daily biological data processing, statistics, and visualization.

Deletion of gene contributes to reduce programmed cell death induced by acetic acid stress in .

Background: Programmed cell death (PCD) induced by acetic acid, the main by-product released during cellulosic hydrolysis, cast a cloud over lignocellulosic biofuel fermented by and became a burning problem. Atg22p, an ignored integral membrane protein located in vacuole belongs to autophagy-related genes family; prior study recently reported that it is required for autophagic degradation and efflux of amino acids from vacuole to cytoplasm. It may alleviate the intracellular starvation of nutrition caused by Ac and increase cell tolerance.

RNA-Seq-based transcriptomic and metabolomic analysis reveal stress responses and programmed cell death induced by acetic acid in Saccharomyces cerevisiae.

As a typical harmful inhibitor in cellulosic hydrolyzates, acetic acid not only hinders bioethanol production, but also induces cell death in Saccharomyces cerevisiae. Herein, we conducted both transcriptomic and metabolomic analyses to investigate the global responses under acetic acid stress at different stages. There were 295 up-regulated and 427 down-regulated genes identified at more than two time points during acetic acid treatment (150 mM, pH 3.

Bacterial Diversity Analysis during the Fermentation Processing of Traditional Chinese Yellow Rice Wine Revealed by 16S rDNA 454 Pyrosequencing.

Rice wine is a traditional Chinese fermented alcohol drink. Spontaneous fermentation with the use of the Chinese starter and wheat Qu lead to the growth of various microorganisms during the complete brewing process. It's of great importance to fully understand the composition of bacteria diversity in rice wine in order to improve the quality and solve safety problems.

Optimization of culture medium compositions for gellan gum production by a halobacterium Sphingomonas paucimobilis.

The effect of culture medium compositions on gellan gum production produced by fermentation with a halobacterium Sphingomonas paucimobilis QHZJUJW CGMCC2428 was studied. In this work, a fractional factorial design was applied to investigate the main factors that affected gellan gum production by S. paucimobilis QHZJUJW CGMCC2428.

Ethyl Carbamate in Fermented Beverages: Presence, Analytical Chemistry, Formation Mechanism, and Mitigation Proposals.

Ethyl carbamate (EC) commonly found in fermented beverages has been verified to be a multisite carcinogen in experimental animals. EC was upgraded to Group 2A by the Intl. Agency for Research on Cancer (IARC) in 2007, which indicates that EC is a probable carcinogen to humans.

Production and identification of mannosylerythritol lipid-A homologs from the ustilaginomycetous yeast Pseudozyma aphidis ZJUDM34.

Mannosylerythritol lipids (MELs) are mainly produced by strains of the genus Pseudozyma and by Ustilago maydis. These glycolipid biosurfactants exhibit not only excellent surface-active properties but also versatile bioactivities. Mannosylerythritol lipid-A (MEL-A) is worth investigating due to its self-assembling property.

[Advance in glycolipid biosurfactants--mannosylerythritol lipids].

Mannosylerythritol lipids (MELs), mainly produced by Ustilago and Pseudozyma, are surface active compounds that belong to the glycolipid class of biosurfactants. MELs have potential application in food, pharmaceutical and cosmetics industries due to their excellent surface activities and other peculiar bioactivities. In recent years, the research field of MELs has regained much attention abroad.

Biodegradation of chestnut shell and lignin-modifying enzymes production by the white-rot fungi Dichomitus squalens, Phlebia radiata.

As a discarded lignocellulosic biomass, chestnut shell is of great potential economic value, thus a sustainable strategy is needed and valuable for utilization of this resource. Herein, the feasibility of biological processes of chestnut shell with Dichomitus squalens, Phlebia radiata and their co-cultivation for lignin-modifying enzymes (LMEs) production and biodegradation of this lignocellulosic biomass was investigated under submerged cultivation. The treatment with D.

Gastrodin production from p-2-hydroxybenzyl alcohol through biotransformation by cultured cells of Aspergillus foetidus and Penicillium cyclopium.

The objective of this work was to take advantage of the resting cells of suitable fungus as an in vitro model to prepare gastrodin from p-2-hydroxybenzyl alcohol (HBA), which mainly exists in the metabolites of the plant Gastrodia elata Blume. The one-step biotransformation of HBA into gastrodin was examined with the filamentous fungi cells of Aspergillus foetidus and Penicillium cyclopium AS 3.4513 in this study.

The synergistic effect on production of lignin-modifying enzymes through submerged co-cultivation of Phlebia radiata, Dichomitus squalens and Ceriporiopsis subvermispora using agricultural residues.

The lignin-modifying enzymes (LMEs) play an important role in decomposition of agricultural residues, which contain a certain amount of lignin. In this study, the production of LMEs by three co-cultivated combinations of Phlebia radiata, Dichomitus squalens and Ceriporiopsis subvermispora and the respective monocultures was comparatively investigated. Laccase and manganese peroxidases (MnP) were significantly promoted in the co-culture of P.

Production of 8-prenylnaringenin from isoxanthohumol through biotransformation by fungi cells.

8-Prenylnaringenin (8PN), which presents in hop, enjoys fame as the most potential phytoestrogen. Although a number of health effects are attributed to 8PN, few reports are available about the production of it. In this work, screening of fungi to efficiently transform isoxanthohumol (IXN) into 8PN was designed.
