The invention provides an assay for identifying a bacterium capable of binding elemental heavy metal, comprising the following steps: cultivating a test bacterium in a suitable first culture medium; immersing at least a surface portion of a test tool into the first culture medium for a second predetermined period of time, said surface portion being coated by elemental heavy metal, respectively; removing said test tool from said first culture medium and optionally rinsing the test tool; contacting a second culture medium with the surface portion coated by elemental heavy metal of said test tool removed in the previous step; and identifying the test bacterium as being capable of binding elemental heavy metal from growth of the test bacterium in said second culture medium.

Biological ore processing for the isolation of heavy metals

The invention relates to a dispersion containing at least one rhamnolipid derivative and also to the use of the rhamnolipid derivatives as emulsifier or dispersing aid.

Rhamnolipid derivatives as emulsifiers and dispersing aids

The invention provides derivatives of rhamnolipids, formulations comprising these, and the use thereof.

Rhamnolipid amides for hair scent retention

The invention provides a process of isolating or enriching a heavy metal present in a liquid medium. The process comprising the following steps: (a) incubating a suspension containing (i) particulate scrap metal, household waste and/or industrial waste containing a heavy metal in elemental form and (ii) biomass comprising a bacterium, or a combination of two or more bacteria, capable of binding the heavy metal; (b) separating the biomass having bound heavy metal from the suspension of step (a); and (c) isolating the heavy metal from the biomass separated in step (b).

Biological processing of scrap metal, household waste and/or industrial waste for the isolation of heavy metals

The invention provides ester derivatives of rhamnolipids, formulations comprising these, and the use thereof.

Rhamnolipid esters as nonionic surfactants for cosmetic use

The invention provides a process of isolating or enriching a heavy metal present in a suspension containing a particulate mineral ore containing a heavy metal, comprising the following steps: incubating a suspension containing (i) a particulate mineral ore containing a heavy metal and (ii) biomass comprising a bacterium capable of binding the heavy metal; separating the biomass having bound heavy metal from the suspension of the previous step; and isolating the heavy metal from the biomass separated in the previous step.
