Arbuscular mycorrhizal associations and the major regulators

Li XUE, Ertao WANG

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3,   Pages 296-306 doi: 10.15302/J-FASE-2020347

Abstract:

Plants growing in natural soils encounter diverse biotic and abiotic stresses and have adapted with sophisticated strategies to deal with complex environments such as changing root system structure, evoking biochemical responses and recruiting microbial partners. Under selection pressure, plants and their associated microorganisms assemble into a functional entity known as a holobiont. The commonest cooperative interaction is between plant roots and arbuscular mycorrhizal (AM) fungi. About 80% of terrestrial plants can form AM symbiosis with the ancient phylum Glomeromycota. A very large network of extraradical and intraradical mycelium of AM fungi connects the underground biota and the nearby carbon and nutrient fluxes. Here, we discuss recent progress on the regulators of AM associations with plants, AM fungi and their surrounding environments, and explore further mechanistic insights.

Value Management Practices on Major Construction Projects and Green Building

Ru-jiang Zhao,Wung Hee Moh

Frontiers of Engineering Management 2016, Volume 3, Issue 2,   Pages 147-157 doi: 10.15302/J-FEM-2016018

Abstract: The paper starts with background information on value management (VM) in the construction industry and current development situation of the green building industry, and costs and profitability of green buildings. The paper continues with detailed analyses of the findings, covering new developments and perceptions of VM, and applications of VM in the industry. The paper also reports case studies on the practices adopted in the planning and design management phase of SIPO Guangdong Patent Examination Cooperation Center and in the construction management phase of Guangzhou International Bio-Island Standard Property Unit II project. As revealed by the practices, the value-adds and savings in construction costs through the application of VM are important for the developers, and the contributions of VM application in green building projects are significant to achieving the expected targets and to resolving the design and construction challenges encountered in the development of green building industry. And the paper presents, findings on how VM can improve construction management and coordination of several ongoing construction projects and on how VM can be systematically implemented by phases, and discussions on other potential benefits of using VM systems.

Environmental and human health impact assessment of major interior wall decorative materials

Bingqing ZHANG, Ruochen ZENG, Xiaodong LI

Frontiers of Engineering Management 2019, Volume 6, Issue 3,   Pages 406-415 doi: 10.1007/s42524-019-0025-4

Abstract: Despite the growing interest in green products in the interior wall decorative material market, knowledge gaps exist because determining which product is more environmental and user friendly than the others is difficult. This work assesses the environmental and human health profiles of interior latex and wallpaper. Two interior latex products of different raw material ratios and one non-woven wallpaper product are considered. The environmental impact assessment follows life cycle assessment (LCA) methodology and applies Building Environmental Performance Analysis System (BEPAS). The human health impact is based on impact-pathway chain and is performed using Building Health Impact Analysis System (BHIAS). The assessment scope, associated emissions, and territorial scope of various emissions are defined to facilitate comparison study of interior wall decorative products. The impacts are classified into 15 categories belonging to three safeguard areas: ecological environment, natural resources, and human health. The impacts of categories are calculated and monetized using willingness to pay (WTP) and disability-adjusted life year (DALY) and summarized as an integrated external cost of environmental and human health impacts. Assessment results reveal that the integrated impact of interior latex is lower than that of non-woven wallpaper, and the interior latex of low quality causes low life cycle integrated impact. The most impacted categories are global warming, respiratory effects, and water consumption. Hotspots of product manufacturing are recognized to promote green product design.

Screening of potential aquatic probiotics from the major microflora of guppies (

Aparna BALAKRISHNA, T. R. KEERTHI

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2,   Pages 163-173 doi: 10.1007/s11705-012-1283-4

Abstract: The fish ( ) was used as the source for probiotics. 46 bacterial isolates were obtained from the skin, gills, guts and intestines of the guppy, (collected from a government model fish farm in Kottayam, India). Of the above isolated strains, four isolates were selected based on their inhibitory spectrum against five indicator strains, 1739, 3906, 2495, 1271 and 1424 (standard cultures collected from Microbial Type Culture Collection (MTCC) Chandigarh, India). Among the resulting isolates, two were gram-positive cocci, namely MBTU-PB2 and MBTU-PB3 and belong to the genus . The other two were gram-negative rods, namely MBTU-PB1 and MBTU-PB4, of the genera and , respectively. The basic probiotic characteristics of these isolates such as the production of bacteriocin like inhibitory substances (BLIS), antibiotic sensitivities and growth profiles were also determined. The above four isolated strains exhibited different antagonisms than the five indicator strains. During incubation, the antibacterial activity gradually increased in the inhibition zone and was influenced by the lag period ( ) and doubling time. The lag periods for most of the four selected strains were shorter than those of the indicator strains and the isolates had different growth rates ( ) than the indicator strains. All four isolates produced BLIS, however, the strains had different BLIS activities against the indicator strains. Treatment of the neutralized cell free supernatants of the selected isolates with proteases eliminated or reduced the BLIS activity, suggesting a proteinaceous nature of the inhibitory compounds. Further, the optimum BLIS activity was observed at neutral pH after 18 h of incubation. The antibiotic sensitivity assay revealed that the isolates were susceptible to routinely used antibiotics, whereas the plasmid profiles showed that the plasmids had no role in the antagonistic properties of the four isolated strains. The results showed that the isolates could be a promising source for biocontrol agents in aquacultures.
