“…These areas were probably also a source of microbes and organic matter essential to the survival of heterotrophic microbes. According to numerous sources [11,[57][58][59], microbial communities have a major influence on a forming ecosystem. From year to year, deposited ash was colonized by microbes-first the base, partially already built of colonized material, then the middle and finally the top of the landfill, the last and furthest situated from the natural source of microbes.…”

Coal bottom and fly ash waste continue to be generated as a result of energy production from coal in the amount of about 750 million tonnes a year globally. Coal is the main source of energy in Poland, and about 338 million tonnes of combustion waste has already been landfilled. The aim of the research was to identify factors determining the Cd, Pb, Zn and Cu phytostabilisation by vegetation growing on a coal combustion waste landfill. Soil and shoots of the following plants were analysed: wood small-reed, European goldenrod, common reed; silver birch, black locust, European aspen and common oak. The influence of the location where the plants grew and the influence of the interaction between the two factors (species and location) were significant. The tree species were more effective at accumulating heavy metals than the herbaceous plants. European aspen had the highest Bioaccumulation Factor (BCF) for cadmium and zinc. A high capacity to accumulate these elements was also demonstrated by silver birch, and in the case of cadmium, by common oak. Accumulation of both lead and copper was low in all plants. The Translocation Factors (TF) indicated that the heavy metals were accumulated mainly in the roots. European aspen, silver birch and European goldenrod were shown to be most suitable for stabilization of the metals analysed in the research.

“…Bioventing may be combined with vacuum‐enhanced pumping for treating the contaminants in saturated and unsaturated zones (bioslurping). We may also either introduce specific bacteria to enrich the target bacteria (bioaugmentation) or add specific nutrients to stimulate the activity of targeted bacteria (biostimulation; Malhotra, Mishra, Karmakar, & Sharma, ).…”

Theories in soil biology, such as plant–microbe interactions and microbial cooperation and antagonism, have guided the practice of ecological restoration (ecorestoration). Below‐ground biodiversity (bacteria, fungi, invertebrates, etc.) influences the development of above‐ground biodiversity (vegetation structure). The role of rhizosphere bacteria in plant growth has been largely investigated but the role of phages (bacterial viruses) has received a little attention. Below the ground, phages govern the ecology and evolution of microbial communities by affecting genetic diversity, host fitness, population dynamics, community composition, and nutrient cycling. However, few restoration efforts take into account the interactions between bacteria and phages. Unlike other phages, filamentous phages are highly specific, nonlethal, and influence host fitness in several ways, which make them useful as target bacterial inocula. Also, the ease with which filamentous phages can be genetically manipulated to express a desired peptide to track and control pathogens and contaminants makes them useful in biosensing. Based on ecology and biology of filamentous phages, we developed a hypothesis on the application of phages in environment to derive benefits at different levels of biological organization ranging from individual bacteria to ecosystem for ecorestoration. We examined the potential applications of filamentous phages in improving bacterial inocula to restore vegetation and to monitor changes in habitat during ecorestoration and, based on our results, recommend a reorientation of the existing framework of using microbial inocula for such restoration and monitoring. Because bacterial inocula and biomonitoring tools based on filamentous phages are likely to prove useful in developing cost‐effective methods of restoring vegetation, we propose that filamentous phages be incorporated into nature‐based restoration efforts and that the tripartite relationship between phages, bacteria, and plants be explored further. Possible impacts of filamentous phages on native microflora are discussed and future areas of research are suggested to preclude any potential risks associated with such an approach.

“…In silico analysis using antiSMASH ( 12 ) and RAST revealed the presence of a siderophore gene cluster and genes involved with the production of indole acetic acid (IAA), a plant hormone associated with plant growth ( 13 ). Furthermore, the genome sequence indicates the presence of pyrroloquinoline quinone synthase and glucose dehydrogenase (implicated in the production of gluconic acid) and 2-ketogluconic acid production (involved in mineral phosphate solubilization) ( 14 ).…”
