Production of succinic acid through the fermentation of Actinobacillus succinogenes on the hydrolysate of Napier grass Tập 15 Số 1 - 2022
Jhih-Sing Lee, Cheng-Jia Lin, Wen‐Chien Lee, Hsin-Yi Teng, Meng-Hsin Chuang
Abstract Background Napier grass biomass can be hydrolyzed mainly containing
glucose and xylose after alkaline pretreatment and enzymatic hydrolysis. This
biomass can be fermented using Actinobacillus succinogenes to produce succinic
acid. The yield of succinic acid was 0.58 g/g. Because metabolizing xylose could
produce more acetic acid, this yield of succinic acid was lower than that
achieved us... hiện toàn bộ
Physiological and comparative transcriptome analyses reveal the mechanisms underlying waterlogging tolerance in a rapeseed anthocyanin-more mutant Tập 15 Số 1
Lei Ding, Rui Li, Li Teng, Ming Li, Xiaoyan Liu, Weijie Wang, Yu Yao, Jun Cao, Xiao‐Li Tan
Abstract Background Rapeseed (Brassica napus) is the second largest oil crop
worldwide. It is widely used in food, energy production and the chemical
industry, as well as being an ornamental. Consequently, it has a large economic
value and developmental potential. Waterlogging is an important abiotic stress
that restricts plant growth and development. However, little is known about the
molecular m... hiện toàn bộ
Current challenges of high-solid anaerobic digestion and possible measures for its effective applications: a review Tập 15 Số 1
Julius Akinbomi, Regina J. Patinvoh, Mohammad J. Taherzadeh
AbstractThe attention that high solids anaerobic digestion process (HS-AD) has
received over the years, as a waste management and energy recovery process when
compared to low solids anaerobic digestion process, can be attributed to its
associated benefits including water conservation and smaller digester foot
print. However, high solid content of the feedstock involved in the digestion
process pos... hiện toàn bộ
Critical metabolic pathways and genes cooperate for epoxy fatty acid-enriched oil production in developing seeds of Vernonia galamensis, an industrial oleaginous plant
Yan Sun, Baoling Liu, Jinai Xue, Xiaodan Wang, Hongli Cui, Runzhi Li, Xiaoyun Jia
Abstract Background Vernonia galamensis native to Africa is an annual oleaginous
plant of Asteraceae family. As a newly established industrial oil crop, this
plant produces high level (> 70%) of vernolic acid
(cis-12-epoxyoctadeca-cis-9-enoic acid), which is an unusual epoxy fatty acid
(EFA) with multiple industrial applications. Here, transcriptome analysis and
fatty acid profiling from developin... hiện toàn bộ
Secretion of collagenases by Saccharomyces cerevisiae for collagen degradation
Han Xiao, Xiufang Liu, Yunzi Feng, Lin Zheng, Ming Zhao, Mingtao Huang
Abstract Background The production and processing of animal-based products
generates many collagen-rich by-products, which have received attention both for
exploitation to increase their added value and to reduce their negative
environmental impact. The collagen-rich by-products can be hydrolyzed by
collagenases for further utilization. Therefore, collagenases are of benefit for
efficient collagen... hiện toàn bộ
Microalgal photoautotrophic growth induces pH decrease in the aquatic environment by acidic metabolites secretion Tập 15 Số 1
Mingcan Wu, Guimei Wu, Feimiao Lu, Hongxia Wang, Anping Lei, Jiangxin Wang
Abstract Background Microalgae can absorb CO2 during photosynthesis, which
causes the aquatic environmental pH to rise. However, the pH is reduced when
microalga Euglena gracilis (EG) is cultivated under photoautotrophic conditions.
The mechanism behind this unique phenomenon is not yet elucidated. Results The
present study evaluated the growth of EG, compared to Chlorella vulgaris (CV),
as the co... hiện toàn bộ
Energy-efficient recovery of fermented butyric acid using octyl acetate extraction - 2022
Hyeon Woo Oh, Seong Chan Lee, Hee Chul Woo, Young Han Kim
Abstract Background A butyric acid recovery process using octyl acetate is
proposed, and the design details of the extraction and subsequent distillation
processes were investigated. Ternary equilibrium data for the extractor design
were derived from molecular simulations and experimental measurements. Results A
new procedure for estimating the thermodynamic parameters was introduced to

Thermotolerance improvement of engineered Saccharomyces cerevisiae ERG5 Delta ERG4 Delta ERG3 Delta, molecular mechanism, and its application in corn ethanol production Tập 16 Số 1
Peizhou Yang, Wenjing Wu, Jianchao Chen, Suwei Jiang, Zhi Zheng, Yanhong Deng, Jiuling Lu, Hu Wang, Yong Zhou, Yuyou Geng, Kanglin Wang
Abstract Background The thermotolerant yeast is beneficial in terms of
efficiency improvement of processes and reduction of costs, while Saccharomyces
cerevisiae does not efficiently grow and ferment at high-temperature conditions.
The sterol composition alteration from ergosterol to fecosterol in the cell
membrane of S. cerevisiae affects the thermotolerant capability. Results In this
study, S. c... hiện toàn bộ
Biotechnologies for bulk production of microalgal biomass: from mass cultivation to dried biomass acquisition

AbstractMicroalgal biomass represents a sustainable bioresource for various
applications, such as food, nutraceuticals, pharmaceuticals, feed, and other
bio-based products. For decades, its mass production has attracted widespread
attention and interest. The process of microalgal biomass production involves
several techniques, mainly cultivation, harvesting, drying, and pollution
control. These te... hiện toàn bộ
The α-mating factor secretion signals and endogenous signal peptides for recombinant protein secretion in Komagataella phaffii
Chenwei Zou, Lingfang Lu, Shengyan Wang, Chenshan Zhang, Xuequn Chen, Yao Lin, Yide Huang
Abstract Background The budding yeast Komagataella phaffii (Pichia pastoris) is
widely employed to secrete proteins of academic and industrial interest. For
secretory proteins, signal peptides are the sorting signal to direct proteins
from cytosol to extracellular matrix, and their secretion efficiency directly
impacts the yields of the targeted proteins in fermentation broth. Although the
α-matin... hiện toàn bộ
