“…The presence of a small amount of acetic acid (3) is due to the natural biological oxidation of ethanol and the action of yeast is also produces with a wellmanaged fermentation. Further, alcohols such as propanol (4) and butanol (5) were recorded as well as glycerol (8), which is also a by-product of the fermentation of starch into ethanol, as well as acrylic acid (6). Residues of saczyme enzyme of glucopyranose (9) and glucopiranoside (10) are found here in small amounts.…”

“…According to the results of this time-dependent study, much lower amounts of coco peat may be enough to satisfy long-term remediation goals. Leita et al (2011) reported that glucose increased the rate of Cr(VI) reduction by promoting the growth of indigenous microbial biomass. The reducing efficiency was more than 90% within 3 days.…”

“…This discrepancy may be due to the much higher concentration of Cr(VI) in our present study. Leita et al (2011) spiked the soil under study with as low as 3 and 10 mg Cr(VI) kg −1 . Suksabye et al (2009) using electron spin resonance (ESR) technique confirmed the reduction of Cr(VI) to Cr(III) by coco peat.…”

“…It is known that Sr can be incorporated in clay minerals (Chen et al, 1998), adsorbed by Fe oxides (Parkman et al, 1998) and complexed by organic matter by forming chelates of varying stability (Leita et al, 2009;2011). To date, the criteria used to predict the eco-availability of metals has been related to the capacity of extractant solutions [ethylenediaminetetraacetic acid (EDTA), diethylene triamine pentaacetic acid (DTPA), weak acids] to remove metals from the surfaces of soil colloids (see also ISO 17402).…”

The main aim of our work was to assess whether strontium (Sr) affects soil microbial biomass size and activity, and the involvement of said biomass in the availability process of the metal. In addition, information concerning the distribution and mobility of the stable element within ecosystems may allow the prediction of the behaviour of its radioisotope counterpart, 90 Sr. Samples were collected in the surroundings of a strontium mine and characterised for total and diethylene triamine pentaacetic acid (DTPA)-extractable Sr, total organic C (TOC), microbial biomass C (MBC), MBC/TOC ratio and metabolic quotient (qCO 2 ). Moreover, MBC and DTPA-extractable Sr were measured during a 45-day incubation experiment of samples soils amended with maize. Overall, increased levels of total Sr had a negative effect on both TOC and MBC. DTPA-extractable Sr was significantly correlated to MBC/TOC suggesting a possible role of soil microbial biomass in the mobilisation of the element. The synthesis of new microbial biomass after soil amendment was negatively affected by the initial content of DTPA-extractable Sr. Conversely, there was a linear positive relationship between newly formed MBC and DTPA-extractable Sr during the incubation, indicating that soil microbial biomass may promote the mobilisation of Sr. These findings indicate that soil amendment with easily degradable organic substrate significantly increases Sr mobility and availability.
