BACKGROUND Single cell oil (SCO) production from lignocelluloses by oleaginous microorganisms is still high in production cost, making the subsequent production of biofuels inviable economically in such an era of low oil prices. Therefore, how to upgrade the final products of lignocellulose-based bioprocess to more valuable ones is becoming a more and more important issue. RESULTS Differently...

The fit of the Eyring-Stover statistical survival theory was found to be precise when applied to diverse soil-related functions.

Aim: The study aimed at isolation and preliminary characterization of anaerobic bacteria from a special crossbreed of Muturu and N’Dama cattle found in parts of Nigeria. Study Design: The work investigated the suitability of the isolates in in vitro fermentation of biomass and evaluated the relationship between the bacterial flora and their ability to hydrolyse lignocellulosic materials from co...

Understanding the genetic factors that govern microbe-sediment interactions in aquatic environments is important for water quality management and reduction of waterborne disease outbreaks. Although chemical properties of bacteria have been identified that contribute to initiation of attachment, the outer membrane proteins that contribute to these chemical properties still remain unclear. In thi...

Recent studies of SOC storage and turnover have employed 13C natural abundance ( 13C) as an in situ Soil organic carbon (SOC) is sensitive to management of tillage, marker of relic and recent SOC pools. Mass concentraresidue (stover) harvest, and N fertilization in corn (Zea mays L.), tions of SOC and the 13C signature are sufficient to but little is known about associated root biomass includin...

BACKGROUND Considerable works have been reported concerning the obstruction of enzymatic hydrolysis efficiency by lignin. However, there is a lack of information about the influence of lignin on the adsorption of cellulases on cellulose, along with the hydrolytic activity of the cellulases adsorbed on lignin. In addition, limited discovery has been reported about the influence of additives on c...

Nitrogen (N) and potassium (K) fertility management of maize (Zea mays L.) in the humid subtropical Mississippi Delta may differ from a temperate climate because of its use in rotation with cotton (Gossypium hirsutum L.), soil temperatures rarely falling to 08C, and heavy winter rains that facilitate nutrient losses. An experiment to determine the [N] (concentration 1⁄4 [ ]), phosphorus [P], [K...

The purpose of this paper is to develop analogs of the E2 model structures of Dwyer, Kan and Stover for categories related to pointed bisimplicial presheaves and simplicial presheaves of spectra. The development is by analogy with and builds on the work of Dwyer, Kan and Stover [1], [2], along with later work of Goerss and Hopkins [3]. The technical challenge met in the present paper is that no...

BACKGROUND Although α-linked xylose is a major constituent of the hemicelluloses of land plants, few secreted α-xylosidases have been described from fungi or bacteria. AxlA of Aspergillus niger is a secreted α-xylosidase that was earlier shown to promote the release of free glucose (Glc) and xylose (Xyl) from substrates containing α-linked xylose, including isoprimeverose (IP), the heptasacchar...

BACKGROUND Microbial consortia represent promising candidates for aiding in the development of plant biomass conversion strategies for biofuel production. However, the interaction between different community members and the dynamics of enzyme complements during the lignocellulose deconstruction process remain poorly understood. We present here a comprehensive study on the community structure an...
