Background. Rapid industrialization and anthropogenic activities such as the unmanaged use of agro-chemicals, fossil fuel burning and dumping of sewage sludge have caused soils and waterways to be severely contaminated with heavy metals. Heavy metals are non-biodegradable and persist in the environment. Hence, remediation is required to avoid heavy metal leaching or mobilization into environmental segments and to facilitate their extraction.Objectives. The present work briefly outlines the environmental occurrence of heavy metals and strategies for using microorganisms for bioremediation processes as reported in the scientific literature.Methods. Databases were searched from different libraries, including Google Scholar, Medline and Scopus. Observations across studies were then compared with the standards for discharge of environmental pollutants.Discussion. Bioremediation employs microorganisms for removing heavy metals. Microorganisms have adopted different mechanisms for bioremediation. These mechanisms are unique in their specific requirements, advantages, and disadvantages, the success of which depends chiefly upon the kind of organisms and the contaminants involved in the process.Conclusions. Heavy metal pollution creates environmental stress for human beings, plants, animals and other organisms. A complete understanding of the process and various alternatives for remediation at different steps is needed to ensure effective and economic processes.Competing interests.

Abstract The study outlines an economical biorefinery concept to evaluate the potential of three aquatic weeds Eichhornia crassipes, Lemna minor and Azolla microphylla for co-production of ethanol and methane. Four different scenarios were investigated viz., scenario A-hydrothermal treatment followed by anaerobic digestion and ethanol fermentation respectively (HT → AD → EF), scenario B- thermochemical treatment followed by anaerobic digestion and ethanol fermentation respectively (TC → AD → EF), scenario C- hydrothermal treatment followed by ethanol fermentation and anaerobic digestion respectively (HT → EF → AD) and scenario D- thermochemical treatment followed by ethanol fermentation and anaerobic digestion respectively (TC → EF → AD). Sequential hydrothermal treatment and anaerobic digestion (HT → AD) in scenario A enhanced the hemicellulose removal by 68.5–73.5% and simultaneously enriched the cellulose content by 41.2–54.5%. This contributed to highest ethanol yield (0.167–0.231 g/g biomass) in scenario A, which was found comparable to that obtained in scenario D, wherein harsh and expensive thermochemical pretreatment was employed. Besides that, relatively higher methane yield of 209–257 dm3/kg TOCR (Total organic carbon removal) obtained in scenario A as compared to other scenarios (67.5–238 dm3/kg TOCR) improved the overall energy efficiency of the studied concept. The energetic assessment showed lowest total energy output (859.6–1322.7 kwh) in scenario B and C as compared to other scenarios (1041.8–1583.9 kwh), thereby confirming their incompetence in coupled bioenergy production. This study, therefore presents an economically and energetically sustainable approach for pretreatment and bioenergy production that could help in overcoming the constraints hindering the commercialization of cellulosic ethanol. The study also opens up possibility for development of coupled aquatic weeds-based wastewater treatment and bioenergy production system for an efficient exploitation of the phytoremediation property of aquatic weeds.

Mycoremediation is one of the biotechniques that recruits fungi to remove toxic pollutants from environment in an efficient and economical manner. Mushrooms, macro-fungi, are among the nature’s most important mycoremediators. Pleurotus species (also called oyster mushrooms) are considered to be the most popular and widely cultivated varieties worldwide and this might be attributed to their low production cost and higher yields. Apart from their nutritive and therapeutic properties, Pleurotus species have high biosorption potential due to their extensive biomass, i.e. mycelial production. The genus has been reported to accumulate high levels of heavy metals. The current state-of-the art review mainly summarises previous investigations carried out by researchers on different roles and mechanisms played by Pleurotus species on heavy metals mycoremediation.

Sustainable agricultural practices are the answer to multifaceted problems that have resulted due to prolonged and indiscriminate use of chemical based agronomic tools to improve crop productions for the last many decades. The hunt for suitable ecofriendly options to replace the chemical fertilizers and pesticides has thus been aggravated. Owing to their versatile and unmatchable capacities microbial agents offer an attractive and feasible option to develop the biological tools to replace/supplement the chemicals. Exploring the microorganisms that reside in close proximity to the plant is thus a justified move in the direction to achieve this target. One of the most lucrative options is to look into the rhizosphere. Rhizosphere may be defined as the narrow zone of soil that surrounds and get influenced by the roots of the plants. It is rich in nutrients compared to the bulk soil and hence exhibit intense biological and chemical activities. A wide range of macro and microorganisms including bacteria, fungi, virus, protozoa, algae, nematodes and microarthropods co-exist in rhizosphere and show a variety of interactions between themselves as well as with the plant. Plant friendly bacteria residing in rhizosphere which exert beneficial affect on it are called as plant growth promoting rhizobacteria (PGPR). Here we review the structure and bacterial diversity of the rhizosphere. The major points discussed here are: (1) structure and composition of the rhizosphere (2) range of bacteria found in rhizosphere and their interactions with the plant with a particular emphasis on PGPR (3) mechanisms of plant growth promotion by the PGPR (4) rhizosphere competence.
