作者: Zhang, Zenghu; Wu, Yanhong; Zhang, Xiaohua
摘要: The deep-sea environment has rich microbial resources, and these resources have been an important subject in
the efforts to culture microflora. Special devices that maintain in situ pressures have been developed and applied
in culturing piezophilic and hyperpiezophilic microbes. However, culturable microorganisms comprise the
minority of deep-sea microbes (archaea and bacteria), which reflects the disadvantages of traditional cultivation
methods, the ignorance of microbial habitats, and the fastidiousness of microbial growth requirements. This
mini-review introduces the diversity of microbes in the deep sea and discusses the deep-sea species that have
been identified in the past two years. In addition, this review summarizes almost all of the recognized piezophilic
microbes and describes the isolation methods that have been employed. Additionally, we recommend that some
of the methods that have been developed to obtain microbes from surface water, freshwater, sediments, soils and
organisms should be modified to enable the isolation of the deep-sea microbes. It is anticipated that this minireview will provide novel insights into exploration of “uncultured” deep-sea microbial resources.2018-01-04T20:07:40ZModulation of the Acetone/Butanol Ratio during Fermentation of Corn Stover-derived Hydrolysate by Clostridium beijerinckii NCIMB 8052Zi-Yong LiuXiu-Qing YaoQuan ZhangZhen LiuZe-Jie WangYong-Yu ZhangFu-Li Lihttp://ir.qibebt.ac.cn:80/handle/337004/98382018-08-27T23:02:04Z2018-01-04T20:07:39Z题名: Modulation of the Acetone/Butanol Ratio during Fermentation of Corn Stover-derived Hydrolysate by Clostridium beijerinckii NCIMB 8052

摘要: Producing biobutanol from lignocellulosic biomass has shown promise
to ultimately reduce greenhouse gases and alleviate the global energy crisis. However, because of the recalcitrance of a lignocellulosic biomass, a pretreatment of the
substrate is needed which in many cases releases soluble lignin compounds (SLCs),
which inhibit growth of butanol-producing clostridia. In this study, we found that
SLCs changed the acetone/butanol ratio (A/B ratio) during butanol fermentation. The
typical A/B molar ratio during Clostridium beijerinckii NCIMB 8052 batch fermentation
with glucose as the carbon source is about 0.5. In the present study, the A/B molar
ratio during batch fermentation with a lignocellulosic hydrolysate as the carbon
source was 0.95 at the end of fermentation. Structural and redox potential changes of
the SLCs were characterized before and after fermentation by using gas chromatography/mass spectrometry and electrochemical analyses, which indicated that some exogenous SLCs were involved in distributing electron flow to C. beijerinckii, leading to modulation of the redox balance. This was further demonstrated by the NADH/NAD ratio
and trxB gene expression profile assays at the onset of solventogenic growth. As a result, the A/B ratio of end products changed significantly during C. beijerinckii fermentation using corn stover-derived hydrolysate as the carbon source compared to glucose as
the carbon source. These results revealed that SLCs not only inhibited cell growth but
also modulated the A/B ratio during C. beijerinckii butanol fermentation.2018-01-04T20:07:39ZCarbon sequestration processes and mechanisms in coastal mariculture environments in ChinaZhang, YongyuZhang, JihongLiang, YantaoLi, HongmeiLi, GangChen, XiaoZhao, PengJiang, ZengjieZou, DinghuiLiu, XiaoyongLiu, Jihuahttp://ir.qibebt.ac.cn:80/handle/337004/98372018-08-27T23:02:04Z2018-01-04T20:07:38Z题名: Carbon sequestration processes and mechanisms in coastal mariculture environments in China

摘要: China is the global leader in mariculture production. Increasing sequestered marine carbon (also known as blue
carbon) via mariculture activities is a promising approach for mitigating climate change and promoting the development of a
low-carboneconomy. Mariculture blue carbon is also considered an important component of China’s“sea granary”. In addition to shellfsh and macroalgae yields, which represent carbon removed from mariculture environment, blue carbon also includes
other important components, which have been largely neglected in the past, such as the carbon transformed by microbes,
dissolved organic carbon (mainly referred to as recalcitrant dissolved organic carbon), and sedimentary particulate carbon. Hence,
from different aspects, a comprehensive study on the formation processes and mechanisms of carbon sequestration is of great
signifcance for comprehensively unveiling the carbon sequestration capability in coastal mariculture environment, which will
contribute to the sustainable development of the fshery economy and construction of an ecological civilization. Moreover,it may
add signifcant economic benefts to the futur ecarbon-trading market.2018-01-04T20:07:38ZEstimating primary production of picophytoplankton using the carbon-based ocean productivity model: a preliminary studyLiang, YantaoZhang, YongyuWang, NannanLuo, TingweiZhang, YaoRivkin, Richard Bhttp://ir.qibebt.ac.cn:80/handle/337004/98362018-08-27T23:02:05Z2018-01-04T20:07:37Z题名: Estimating primary production of picophytoplankton using the carbon-based ocean productivity model: a preliminary study

摘要: Picophytoplankton are acknowledged to contribute significantly to primary production
(PP) in the ocean while now the method to measure PP of picophytoplankton (PPPico)
at large scales is not yet well established. Although the traditional 14C method and
new technologies based on the use of stable isotopes (e.g., 13C) can be employed to
accurately measure in situ PPPico, the time-consuming and labor-intensive shortage of
these methods constrain their application in a survey on large spatiotemporal scales.
To overcome this shortage, a modified carbon-based ocean productivity model (CbPM)
is proposed for estimating the PPPico whose principle is based on the group-specific
abundance, cellular carbon conversion factor (CCF), and temperature-derived growth
rate of picophytoplankton. Comparative analysis showed that the estimated PPPico
using CbPM method is significantly and positively related (r2 D 0.53, P < 0.001, n D 171)
to the measured 14C uptake. This significant relationship suggests that CbPM has the
potential to estimate the PPPico over large spatial and temporal scales. Currently this
model application may be limited by the use of invariant cellular CCF and the relatively
small data sets to validate the model which may introduce some uncertainties and
biases. Model performance will be improved by the use of variable conversion factors
and the larger data sets representing diverse growth conditions. Finally, we apply the
CbPM-based model on the collected data during four cruises in the Bohai Sea in 2005.
Model-estimated PPPico ranged from 0.1 to 11.9, 29.9 to 432.8, 5.5 to 214.9, and 2.4
to 65.8 mg C m−2 d−1 during March, June, September, and December, respectively.
This study shed light on the estimation of global PPPico using carbon-based production
model.2018-01-04T20:07:37Z
