Carbon adsorbents derived from biomass (agricultural and household residues) have been widely used in the sequestration of hazardous substances from the environment due to their distinctive qualities of large internal surface area, mechanical integrity, and regeneration. The need for carbon adsorbents for sequestration of dyes, heavy metals, and crude oil components has increased because of environmental concerns. This has led to studies of carbon adsorbents derived from agricultural and household biomass residues. These adsorbents have been used to remove pollutants. Although numerous reviews have been published before, analogy of results obtained using different adsorbents is hard due to dissimilarities in research data. Against this backdrop, the purpose of the research survey was to review the contemporary publications regarding the production of activated carbon from biomass sources highlighting specifically its utilization in removing toxic wastes from water solution such as oil spill, dyes, and sundry hazardous substances. Also the work focuses on the methods for the restoration of the spent adsorbents and their end use.

“…Compared with chemical surfactants, biosurfactants have good environmental compatibility, high surface activity and easy biodegradability. 10,11 The emulsifying activity of biosurfactant and the formation of micelles can disperse and solubilize petroleum hydrocarbons. 12 In oily sludge washing treatment, biosurfactants with high emulsication activity play a stronger role in solubilization of crude oil.…”

The use of efficient green cleaning agents, such as biosurfactants, is important in oil sludge treatment.Enhanced oil recovery from oily sludge by different rhamnolipids was comparatively evaluated. Using crude glycerol, the wild-type strain Pseudomonas aeruginosa SG and the recombinant strains P.aeruginosa PrhlAB and P. stutzeri Rhl produced 1.98 g L À1 , 2.87 g L À1 and 0.87 g L À1 of rhamnolipids, respectively. The three bacterial strains produced different rhamnolipid mixtures under the same conditions. The proportions of mono-rhamnolipids in the three rhamnolipid products were 55.92%, 94.92% and 100%, respectively. These rhamnolipid products also possessed different bioactivities.Emulsifying activity became higher as the proportion of mono-rhamnolipids increased. The three rhamnolipid products were stable at temperatures lower than 121 C, pH values from 5-11 and NaCl concentrations from 0-15%. All three rhamnolipid products could recover oil from oily sludge, but oil recovery efficiency was positively related to the proportion of mono-rhamnolipids. Mono-rhamnolipids produced by the recombinant strain Rhl exhibited the best oil recovery efficiency (53.81%). The results reveal that mono-rhamnolipids are the most promising for oil recovery from oily sludge.

“…The production and overuse of synthetic dyes, pesticides and pharmaceuticals have led to environmental pollution (Doshi et al, 2018;Hu et al, 2018;Allam et al, 2019;. Contaminated sewage and soil usually contain large amounts of heavy metals and metalloids (Choi et al, 2018).…”

In recent decades, the attention of scientists has been drawn towards nanoparticles (NPs) of metals and metalloids. Traditional methods for the manufacturing of NPs are now being extensively studied. However, disadvantages such as the use of toxic agents and high energy consumption associated with chemical and physical processes impede their continued use in various fields. In this article, we analyse the relevance of the use of living systems and their components for the development of "green" synthesis of nano-objects with exceptional properties and a wide range of applications. The use of nano-biotechnological methods for the synthesis of nanoparticles has the potential of large-scale application and high commercial potential. Bacteria are an extremely convenient target for green nanoparticle synthesis due to their variety and ability to adapt to different environmental conditions. Synthesis of nanoparticles by microorganisms can occur both intracellularly and extracellularly. It is known that individual bacteria are able to bind and concentrate dissolved metal ions and metalloids, thereby detoxifying their environment. There are various bacteria cellular components such as enzymes, proteins, peptides, pigments, which are involved in the formation of nanoparticles. Bio-intensive manufacturing of NPs is environmentally friendly and inexpensive and requires low energy consumption. Some biosynthetic NPs are used as heterogeneous catalysts for environmental restoration, exhibiting higher catalytic efficiency due to their stability and increased biocompatibility. Bacteria used as nanofactories can provide a new approach to the removal of metal or metalloid ions and the production of materials with unique properties. Although a wide range of NPs have been biosynthetic and their synthetic mechanisms have been proposed, some of these mechanisms are not known in detail. This review focuses on the synthesis and catalytic applications of NPs obtained using bacteria. Known mechanisms of bioreduction and prospects for the development of NPs for catalytic applications are discussed.
