Xingling Tao, Yabin Zhan, Tao Jiang, Chuanjiong Hu
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105335
Abstract:
The aim of this study is to construct petroleum degrading agent (PDA) which can effectively degrade oil. By enrichment, domestication, and separation of culture from the soil sample of Qianjiang Guanghua Oilfield, the pure culture of three petroleum degrading bacteria G-40, G-53, and G-94 was identified from the medium supplemented with oil, which served as the sole source of carbon. The species of G-40 and G-53 were preliminarily identified and classified by morphological observation, physiological and biochemical determination, and sequence analyses of 16S rDNA. The species of G-94 was preliminarily identified and classified by morphological observation, physiological and biochemical determination, and sequence analyses of ITS rDNA. The optimal inoculation proportion of these three bacteria strains and bran proportion in composition of PDA were determined through orthogonal test. G-40, G-53, and G-94 were isolated and identified as Brevibacillus laterosporus, Tsukamurella inchonensis, and Candida tropicalis, respectively. To construct petroleum degrading agent, the optimum inoculation proportion of the three bacteria strains was A1B3C3 (G-40:G-53:G-94 = 1:4:4); and the optimum proportion of bran was D1E1F2 (soybean meal:corn flour:bran = 1:1:2). The oil removal rate of the constructed petroleum degrading agent reached to 42.32% on day 10 under the optimal proportion of bacteria inoculation and bran composition. Petroleum degrading bacteria can effectively degrade petroleum for its own growth. This study identified three petroleum degrading bacteria strains and proposed a petroleum degrading agent by studying the optimal inoculation proportion of the three bacterial strains and the accompanying bran. Our research could provide potential microbial resources for bioremediation of petroleum-contaminated soil.

Abstract: Four strains with typical morphology of actinomycete genus ofFrankia were isolated from root nodules ofCoriatia nepalensis. They were shown to nodulate the seedlings of host plant and hybridize withFrankia 16S rRNA targeted olionucleotide probes, indicating that they did belong to the genusFrankia. Furthermore, by nifHDK probe hybridizations, the homologous fragments of nifHDK genes were detected among the bacteria, and they were located in various sizes of restriction fragments of total DNA, showing diverse patterns of restriction fragment length polyrnorphisms of nifHDK gene (nifHDK-RFLPs). The PCR-based amplification and cloning of nifH gene throw light on the molecular phylogeny ofCoriaria -infectiveFrankia.

Abstract: A rapid ingel lysis method was used to detect the plasmids among twenty one Frankia strains from Coriaria nepalensis and four confirmed Frankia strains from other host plants belonging to four genera of actinorhizal trees. Five isolates were detected harbouring plasmids which ranged from 13 to 20 kb in size. Both the Frankia strain Hr18 and the isolate Cs466 showed two plasmids, They appered to share the same plasbod pattern according to the size. Based on the number and size of the plasmids detected, twenty one Coriaria isolates were divided into four plasmid groups. The effect of bacterial growth and cell lysis conditions on plasmid detection was also explored.

Abstract: A Frankia-like strain, Cs146, was isolated from nodules of Coriaria nepalensis in southwest China. The isolate is an actinomycete with vesicles and sporangia borne on the hyphae, and shown to have an ability to nodulate the host plant. No aerial hyphae is formed, but the substrate hyphae are usually orange and produce soluble yellow pigment. Cs146 could grow quite slow at 28-30 degrees C on both liquid and solid media. However, the isolate is greatly different from other frankiae in physiology (intermediate physiologocal group between A and B trains), cell wall composition of characteristical amino acids (meso-DAP plus glycine) and whole cell sugar patterns (xylose plus little amount of galactose and arabinose). Cs146 thus appears to be a member of a distinct Frankia lineage.

Abstract: 对从湖北、四川、云南等地采集的尼泊尔马桑(Coriaria nepalensis Wall.)根瘤中分离的20株内生菌纯培养物所进行的研究表明,其形态均具有弗兰克氏菌属的特征。在粗细不一的分枝菌丝体上有泡囊和孢囊,有的还有串珠状结构的菌丝体。不同菌株在液体培养基上生长速度很不一致;菌丝体多呈絮状或颗粒状沉淀,个别还呈薄膜状沉淀;绝大多数菌株的菌丝体具有不同色调的色素;在S培养基中大多数都能产生可溶性色素。上述这些培养特征常因培养基成分和培养方式的不同而有差异。大多数菌株的胞壁组分属Ⅱ型,少数菌株为Ⅲ型;全细胞糖型变化很大,20个菌株可划分为6个糖型,而且绝大多数糖型与已知弗兰克氏菌有所不同。此外,有65%的菌株还具有明显的抗菌活性。

Abstract: 对已知细胞壁为Ⅰ、Ⅱ、Ⅲ和Ⅳ型的21株(10属)放线菌进行了胞壁氨基酸组分的分析。结果表明,所有被检测菌株的细胞壁在氨基酸分析仪上均显示有谷氨酸、甘氨酸、丙氨酸和二氨基庚二酸(DAP)。而同一种胞壁类型的菌株,尽管是不同的种或属,氨基酸的总量也各不相同,但这4种氨基酸的分子比却有一个共同而稳定的相似比值,不同的胞壁类型则有不同的比值。从而使每种胞壁类型具有各自的特征,可以作为鉴别的一种有效指标。实验还发现,4株胞壁为111型的弗兰克氏菌以及Ⅳ型的1株诺卡氏菌和1株地中海拟无技酸菌,在薄层层析中除显示有me

Abstract: Based on the clinical effect of the treatment on 546 Pediatric Shi Ji fever cases, the thesis tries to explore the effectiveness of Traditional Chinese Medicine(TCM) treatment on Pediatric Shi Ji and the relationship between Pediatric Shi Ji and fever. The methodology applied is a retrospective analysis on the clinical curative effect of TCM treatment on Shi Ji fever cases in our hospital from January 2008 to December 2012. And the results show that a total effective rate of 96.3% could be guaranteed through either oral Chinese Medicinal Herbs, Chinese Medicine Enema, Massage Therapy, or navel administration with TCM. The thesis holds that Pediatric Shi Ji may cause fever, which could be cured simply by applying TCM treatment (promoting digestion to eliminate stagnation) with less or no use of antibiotics.
A Variational Model for Removing Multiple Multiplicative Noises  [PDF]
Xuegang Hu, Yan Hu
Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.512075
Abstract: The problem of multiplicative noise removal has been widely studied in recent years. Many methods have been used to remove it, but the final results are not very excellent. The total variation regularization method to solve the problem of the noise removal can preserve edge well, but sometimes produces undesirable staircasing effect. In this paper, we propose a variational model to remove multiplicative noise. An alternative algorithm is employed to solve variational model minimization problem. Experimental results show that the proposed model can not only effectively remove Gamma noise, but also Rayleigh noise, as well as the staircasing effect is significantly reduced.
Training a Quantum Neural Network to Solve the Contextual Multi-Armed Bandit Problem  [PDF]

Abstract: Artificial intelligence has permeated all aspects of our lives today. However, to make AI behave like real AI, the critical bottleneck lies in the speed of computing. Quantum computers employ the peculiar and unique properties of quantum states such as superposition, entanglement, and interference to process information in ways that classical computers cannot. As a new paradigm of computation, quantum computers are capable of performing tasks intractable for classical processors, thus providing a quantum leap in AI research and making the development of real AI a possibility. In this regard, quantum machine learning not only enhances the classical machine learning approach but more importantly it provides an avenue to explore new machine learning models that have no classical counterparts. The qubit-based quantum computers cannot naturally represent the continuous variables commonly used in machine learning, since the measurement outputs of qubit-based circuits are generally discrete. Therefore, a continuous-variable (CV) quantum architecture based on a photonic quantum computing model is selected for our study. In this work, we employ machine learning and optimization to create photonic quantum circuits that can solve the contextual multi-armed bandit problem, a problem in the domain of reinforcement learning, which demonstrates that quantum reinforcement learning algorithms can be learned by a quantum device.
