Diagnosing bioremediation of crude oil-contaminated soil and related geochemical processes at the field scale through microbial community and functional genes Ann. Microbiol. (IF 1.528) Pub Date : 2020-06-15 Pingping Cai, Zhuo Ning, Yaci Liu, Ze He, Jiansheng Shi, Manlan Niu
Bioremediation is widely considered the most desirable procedure for remediation of oil-contaminated soil. Few studies have focused on the relationships among microbial community, functional genes of biodegradation, and geochemical processes during field bioremediation, which provide crucial information for bioremediation. In the current study, the microbial community and functional genes related to

First report of Wolbachia in Damaeus onustus (Acari: Oribatida) Ann. Microbiol. (IF 1.528) Pub Date : 2020-06-15 Edyta Konecka, Ziemowit Olszanowski, Aleksandra Jagiełło
Little is known about the distribution and phylogeny of bacterial endosymbionts in oribatid mites (Acari: Oribatida). Thus, we undertook the issue of occurrence of these microbial symbionts in this arthropod group. We used PCR technique for detection of Wolbachia in Damaeus onustus. Phylogenetic analysis of the bacterium was conducted based on the 16S rDNA sequence. To the best of our knowledge, we

Bacterial community characterization of the rhizobiome of plants belonging to Solanaceae family cultivated in desert soils Ann. Microbiol. (IF 1.528) Pub Date : 2020-05-29 Aarón Barraza, María Goretty Caamal-Chan, Thelma Castellanos, Abraham Loera-Muro
The plant Solanaceae family is one of the most important for global agriculture and nutrition. Within this plant family, two plant species stand out for their economic importance and for human consumption, which are tomato (Solanum lycopersicum) and chili pepper (Capsicum annuum). Moreover, those plants support diverse and characteristic microbial communities that are uniquely suited to the plant habitat

Diversity of hydrolase-producing halophilic bacteria and evaluation of their enzymatic activities in submerged cultures Ann. Microbiol. (IF 1.528) Pub Date : 2020-05-27 Leila Batsoule Drissi Kaitouni, Jaouad Anissi, Khalid Sendide, Mohammed El Hassouni
In this work, we assessed the diversity of culturable halophilic bacteria that produce hydrolytic enzymes from both natural and artificial hypersaline regions in the pre-Rif region of Morocco. Bacteria were isolated from three hypersaline sites, in solid medium supplemented with various salt concentrations ranging from 0 to 330 g/L. Physical and chemical characteristics of samples from the isolation

Expression of a highly active β-glucosidase from Aspergillus niger AS3.4523 in Escherichia coli and its application in gardenia blue preparation Ann. Microbiol. (IF 1.528) Pub Date : 2020-05-19 Shuai Hao, Yuanpu Liu, Yu Qin, Lei Zhao, Jiawen Zhang, Tingting Wu, Baoguo Sun, Chengtao Wang
Gardenia blue is one of the natural food additives used in East Asia for many years. Its biosynthesis relies on a key rate-limiting cellulase: β-glucosidase (BGL), which mainly exists in Aspergillus niger (A. niger) cells. The purpose of this study was to obtain active β-glucosidase by cell engineering method and applied to gardenia blue synthesis, which would help to promote the application and reduce

Regulation and analysis of the diversity of intestinal microbiota in SD rats by Danggui Buxue Tang (DBT) fermented with Bacillus subtilis Ann. Microbiol. (IF 1.528) Pub Date : 2020-05-15 Keyuan Chen, Yan Gao, Xinjian Wang, Feng Cheng, Shahbaz Ul Haq, Yun Liang, Zhiwei Yang, Bo Li, Yuan Liu, Yonggang Wang, Jianping Liang, Baocheng Hao
To investigate the effect of Danggui Buxue Tang (DBT) on intestinal microbiota diversity after fermentation by Bacillus subtilis. B. subtilis was used to ferment DBT. Sprague Dawley (SD) rats were randomly divided into the following four groups with six rats in each group: the control group, DBT nonfermentation group, B. subtilis group, and DBT fermentation group. Rats were fed continuously for 14

Endophytic fungal community in grape is correlated to foliar age and domestication Ann. Microbiol. (IF 1.528) Pub Date : 2020-05-15 Yanchun Fan, Linlin Gao, Pingping Chang, Zhi Li
The composition of endophytic communities has been shown to depend on grape genotypes and viticultural managements in leaves, stems, and berries of grape, but there have been relatively few reports exploring fungal endophytes associated with wild grape and foliar age. The regions of internally transcribed spacer (ITS) were sequenced using the Illumina HiSeq to determine the diversity of fungal endophytes

The complete genome sequence of the archaeal isolate Halomicrobium sp. ZPS1 reveals the nitrogen metabolism characteristics under hypersaline conditions Ann. Microbiol. (IF 1.528) Pub Date : 2020-05-15 Xinyu Hu, Chunlin Zeng, Zhaozhi Hou, Yuan Wang, Qin Xu, Kazuo Isobe, Keishi Senoo, Lin Zhu
As a potential tool for the biodegradation of nitrogen contaminants, including nitrate, nitrite, and ammonium, in pickled foods with high salinity, the halophilic and denitrifying archaeal strain Halomicrobium sp. ZPS1 was isolated from edible salt particles. Under anaerobic and static culture conditions, Halomicrobium sp. ZPS1 could simultaneously degrade nitrate, nitrite, and ammonium in liquid medium

Production, purification, and characterization of cellulase from Acinetobacter junii GAC 16.2, a novel cellulolytic gut isolate of Gryllotalpa africana, and its effects on cotton fiber and sawdust Ann. Microbiol. (IF 1.528) Pub Date : 2020-05-14 Sandipan Banerjee, Tushar Kanti Maiti, Raj Narayan Roy
The study aims to search for potent cellulase producer from the gut of Gryllotalpa africana as well as to characterize and determine the effect of the purified enzyme on the cellulosic waste materials. The potent cellulolytic strain was identified through morphological, biochemical, physiological, and molecular characterization like 16S rRNA and fatty acid methyl ester profile. After the optimization
