Isolation and application of predatory

Ran Yu, Shiwen Zhang, Zhoukai Chen, Chuanyang Li

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 1, doi: 10.1007/s11783-017-0900-3

Abstract: Indigenous predatory BALO strains were successfully isolated from activated sludge. Sludge SRF and CST were significantly reduced by BALOs induced biolysis process. The increase of BALO input dosage promoted the sludge biolysis efficiency. Sludge biolysis disintegrated flocs and lysed cells for internal water release. The optimal sludge biolysis time was 24 h and no pH adjustment was needed. -and-like organisms (BALOs) are a group of ubiquitous and obligate predatory bacteria and commonly used as biocontrol agents. In this study, an efficient, environmental-friendly, and convenient BALOs encouraged municipal waste sludge biolysis pretreatment technique was developed and investigated for dewaterability enhancement of excess waste sludge. The indigenous predatory BALOs were successfully isolated from the sludge for biolysis treatment. Without any chemical addition or pH adjustment, the sludge specific resistance (SRF) and capillary suction time (CST) were significantly reduced by as high as 53.4% and 23.8%, respectively within 24 h’s treatment, which would further be lowered with the increase of BALOs input dosage. However, the continuous extension of reaction time would worsen the sludge dewaterability. The decreases of SRF and CST accompanied with the increases of sludge disintegration degree and soluble chemical oxygen demand, nitrogen, and phosphorus concentrations all emphasized the contributions of BALOs’ predation activities to sludge disturbance, cell lysis, and consequently the release of sludge intracellular water to finally effectively improve the sludge dewaterability and disposal efficiency.

Frontiers of Agricultural Science and Engineering 2015, Volume 2, Issue 1,   Pages 60-65 doi: 10.15302/J-FASE-2015048

Abstract: Novel simple sequence repeat (SSR) markers were developed to evaluate their utility for genetic diversity and breeding studies of and related species. A total of 108 primer pairs were characterized by PCR amplification experiments. Among these, 61 were polymorphic and transferable to other citrus species. The number of alleles per locus ranged from 2 to 6, with an average of 2.37 alleles per locus. The expected heterozygosity and observed heterozygosity ranged from 0 to 0.83 and 0 to 1.00, respectively. These novel polymorphic SSR markers will be useful for citrus cultivar identification and evaluation as well as breeding studies.

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 3,   Pages 330-339 doi: 10.1007/s11705-014-1419-9

Abstract: The putrefaction of alkaline silica sol was investigated in this paper. The total colony numbers in three alkaline silica sol samples were 1.47×10 , 1.25×10 , and 9.45×10 cfu·mL , respectively. The salt- and alkali-tolerant strains were isolated and selected using nutrient agar medium at 2.5% salinity and pH 9.5. Basic morphological, physiological and biochemical tests were conducted to confirm the preliminary characterizations of the strains. Based on API 50 CH test and 16S rDNA gene sequence analysis, the isolated strains were finally identified as sp., sp., and . The survivability of the strains under different conditions such as salinities, acidities and temperatures was also studied. Some suitable methods for degerming, such as product pipe steam sterilization and regular canister cleaning, were proposed. To explore the possibility of isolates in industrial application, their alkaline protease and amylase production abilities were preliminarily studied. Five strains produced alkaline protease, whereas two strains produced alkaline amylase. Thus, understanding of the putrefaction on alkaline silica sol would be beneficial for improving industrial production.

Zhou Fulin,Tan Ping,Liu Dewen

Strategic Study of CAE 2013, Volume 15, Issue 4,   Pages 36-40

Abstract:

Nuclear energy is a carbon-free,  clean and efficient energy. It is very important in the progress of human civilization and modern development of the world. However,  there are still some problems such as nuclear leak and nuclear waste. In this paper,  the world's nuclear energy utilization and nuclear power plant constructions are reviewed and plans are forecasted. The basic reason of previous nuclear power plant accidents in history is summarized. Taking 2011 Tohuku earthquake -fukushima nuclear power station accident as an example, threats to the nuclear power plant by earthquake are investigated and impacts on social,  economic and ecological environment caused by nuclear power station accident are analyzed. This paper drew lessons from previous accidents and put forward a variety of countermeasures which are from both the technical and management aspects. This paper also put forward some suggestions. Security measures of the existing nuclear power plants should be assessed carefully. The long-term construction plan of the nuclear power plant should be improved. In addition,  emergency management mechanism of the nuclear power plant can be enhanced in the future. The earthquake monitoring and earthquake early-warning system is critical and promoted to be established widely. The nuclear probability safety analysis (PSA) could be investigated in depth. The security education of the public should be continuously popularized and disaster drills be carried out regularly. International cooperation and communication are also advocated to be strengthened. All these measures can be significant in human process to explore nuclear energy correctly. We also appeal people all over the world to respect the nature,  enjoy the nature,  and to create and enjoy the new civilization of human beings.

Isolation of highly purity cellulose from wheat straw using a modified aqueous biphasic system

Lifeng YAN, Yi ZHAO, Qing GU, Wan LI

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 3,   Pages 282-291 doi: 10.1007/s11705-012-0901-5

Abstract: Cellulose samples with molecular weights ranging from 8.39 × 10 to 11.00 × 10 g/mol were obtained from wheat straw. The dewaxed wheat straw was pretreated with aqueous hydrochloric acid followed by delignification using an environmentally benign poly(ethyleneglycol)/salt aqueous biphasic system. The yield of cellulose was in the range of 48.9%–55.5% and the cellulose contained 1.2%–3.2% hemicelluloses, and 0.97%–3.47% lignin. All the isolated cellulose samples could be directly dissolved in a 6 wt-% NaOH/4 wt-% urea aqueous solution through a precooling-thawing process to form a homogenous solution. The separation process was investigated and the obtained cellulose and its solution were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and energy dispersive X-ray apparatus, and X-ray diffraction. The results revealed that aqueous soluble cellulose can be directly prepared from wheat straw by this method and this study opens a novel pathway to prepare cellulosic materials from agricultural waste.

Self-deployed execution environment for high performance computing Research Articles

Mingtian SHAO, Kai LU, Wenzhe ZHANG

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6,   Pages 845-857 doi: 10.1631/FITEE.2100016

Abstract:

Traditional (HPC) systems provide a standard preset environment to support scientific computation. However, HPC development needs to provide support for more and more diverse applications, such as artificial intelligence and big data. The standard preset environment can no longer meet these diverse requirements. If users still run these emerging applications on HPC systems, they need to manually maintain the specific dependencies (libraries, environment variables, and so on) of their applications. This increases the development and deployment burden for users. Moreover, the multi-user mode brings about privacy problems among users. Containers like Docker and Singularity can encapsulate the job's , but in a highly customized HPC system, cross-environment application deployment of Docker and Singularity is limited. The introduction of container images also imposes a maintenance burden on system administrators. Facing the above-mentioned problems, in this paper we propose a self-deployed (SDEE) for HPC. SDEE combines the advantages of traditional virtualization and modern containers. SDEE provides an isolated and customizable environment (similar to a virtual machine) to the user. The user is the root user in this environment. The user develops and debugs the application and deploys its special dependencies in this environment. Then the user can load the job to compute nodes directly through the traditional HPC job management system. The job and its dependencies are analyzed, packaged, deployed, and executed automatically. This process enables transparent and rapid job deployment, which not only reduces the burden on users, but also protects user privacy. Experiments show that the overhead introduced by SDEE is negligible and lower than those of both Docker and Singularity.
