Characteristics and Complete Genome Analysis of Bacillus asahii OM18, a Bacterium in Relation to Soil Fertility in Alkaline Soils Under Long-Term Organic Manure Amendment. Curr Microbiol 2019; 76:1512-1519. [PMID: 31511964 DOI: 10.1007/s00284-019-01766-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 08/28/2019] [Accepted: 09/04/2019] [Indexed: 10/26/2022]
Abstract
Bacillus asahii strain OM18, a bacterium in relation to soil fertility, was isolated from alkaline soils under long-term organic manure application in the North China Plain. B. asahii species play a pivotal role in the promotion of both crop yield and soil fertility via accelerating carbon and phosphorus cycling. However, little is known about the characteristics of B. asahii and its underlying molecular mechanism involved in soil nutrient cycling as well as its potential in promoting crop growth. To this end, we report the characteristics and complete genome analysis of strain OM18, which is relevant to promoting plant growth in phosphorus-deficient alkaline soils. Our results provide a glimpse into the metabolic function of B. asahii OM18.

Abstract
A physico-chemical characterization of seawater taken from the fishing harbour of Sfax, Tunisia, revealed a contamination by organic and inorganic micropollutants. An aerobic marine halotolerant Bacillus stratosphericus strain FLU5 was isolated after enrichment on fluoranthene, a persistent and toxic polycyclic aromatic hydrocarbon (PAH). GC-MS analyses showed that strain FLU5 was capable of degrading almost 45 % of fluoranthene (100 mg l(-1)), without yeast extract added, after 30 days of incubation at 30 g l(-1) NaCl and 37 °C. In addition, the isolate FLU5 showed a remarkable capacity to grow on a wide range of aliphatic, aromatic and complex hydrocarbons. This strain could also synthesize a biosurfactant which was capable of reducing the surface tension of the cell-free medium, during the growth on fluoranthene. The biodegradative abilities of PAHs are promising and can be used to perform the bioremediation strategies of seawaters and marine sediments contaminated by hydrocarbons.

Annual ryegrass-associated bacteria with potential for plant growth promotion. Microbiol Res 2014; 169:768-79.

Abstract
Annual ryegrass is a fast-growing cool-season grass broadly present in the Portuguese "montado", a typically Mediterranean agro-forestry-pastoral ecosystem. A culture-dependent approach was used to investigate natural associations of this crop with potentially beneficial bacteria, aiming to identify strains suitable for biofertilization purposes. Annual ryegrass seedlings were used to trap bacteria from three different soils in laboratory conditions. Using a nitrogen-free microaerophilic medium, 147 isolates were recovered from the rhizosphere, rhizoplane, and surface-sterilized plant tissues, which were assigned to 12 genera in classes Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Bacilli and Actinobacteria. All isolates were able to grow in the absence of nitrogen and several of them were able to perform in vitro activities related to plant growth promotion. Isolates of the genera Sphingomonas and Achromobacter were found to be the most effective stimulators of annual ryegrass growth under nitrogen limitation (47-92% biomass increases). Major enhancements were obtained with isolates G3Dc4 (Achromobacter sp.) and G2Ac10 (Sphingomonas sp.). The latest isolate was also able to increment plant growth in nitrogen-supplemented medium, as well as the phosphate solubilizer and siderophore producer, G1Dc10 (Pseudomonas sp.), and the cellulose/pectin hydrolyser, G3Ac9 (Paenibacillus sp.). This study represents the first survey of annual ryegrass-associated bacteria in the "montado" ecosystem and unveiled a set of strains with potential for use as inoculants.

Abstract
Bacillus stratosphericus LAMA 585 was isolated from the Mid-Atlantic-Ridge seafloor (5,500-m depth). This bacterium presents the capacity for cellulase, xylanase, and lipase production when growing aerobically in marine-broth media. Genes involved in the tolerance of oligotrophic and extreme conditions and prospection of biotechnological products were annotated in the draft genome (3.7 Mb).

Abstract
In the present investigation, the abundance and molecular phylogeny of part of the culturable bacterial population involved in the dissolution of “miliolite”, a bioclastic limestone, from Gopnath, India, was studied. Carbonate-dissolving bacteria were isolated, enumerated and screened for their ability to dissolve miliolite. Amplified ribosomal DNA restriction analysis (ARDRA) indicated 14 operational taxonomic units (OTUs) to be distributed in 5 different clades at a similarity coefficient of 0.85. Then, 16S rRNA sequence analysis helped to decipher that the majority of carbonate-dissolving bacteria were affiliated to phyla Firmicutes (Families Bacillaceae and Staphylococcaceae) and Actinobacteria (Family Promicromonosporaceae) indicating their role in miliolite weathering.
