“…The results are displayed in Figure 2. Cyanide concentration above 2.6 mg/L induced a longer lag phase, a result which Kao et al (2003) has also reported. T-test were done using the values obtained at t=30th h. It was determined that there was no significant difference between growth at concentration above 13 mg/L cyanide.…”

“…Different organisms utilize different enzymatic pathways to degrade cyanide into less toxic compounds such as ammonia, carbon dioxide, formic acid or formamide (Gupta et al 2010). Several microorganisms have been found useful for degrading cyanide: Burkholderia cepacia strain C-3 utilized cyanide as the nitrogen source for growth (Adjei & Ohta 2000) and produced ammonia (NH 3 ) and carbon dioxide (CO 2 ) meanwhile Klebsiella oxytoca is capable of biodegrading cyanide into ammonia and methane (Kao et al 2003).…”

“…91 % of 1 mM KCN in 20 h (4) and anaerobically degraded tetracyanonickelate in 60 h (8). In accordance with this study, incubation temperature of 25-30 °C (2-6,8,29), pH= 6.5-7.5 (3)(4)(5)8,(29)(30)(31) and rotation speed of 100-200 rpm (8,29,31,32) were determined as optimal conditions for biodegradation of diff erent cyanide and cyanogen com pounds in diff erent research papers.…”

“…Since cyanide is highly reactive and forms diff erent complexes with transitional metals, it is a dangerous toxic compound for living organisms (4)(5)(6). Additionally, cyanide is also the inhibitor of cytochrome oxidases in electron transport chain, which is a crucial pathway in the respiratory system of bacteria and other organisms (1,3,5,7,8).…”

SummaryIn this study, optimization conditions for cyanide biodegradation by Klebsiella pneumoniae strain were determined to be 25 °C, pH=7 and 150 rpm at the concentration of 0.5 mM potassium cyanide in the medium. Additionally, it was found that K. pneumoniae strain is not only able to degrade potassium cyanide, but also to degrade potassium hexa cyanoferrate(II) trihydrate and sodium ferrocyanide decahydrate with the effi ciencies of 85 and 87.5 %, respectively. Furthermore, this strain degraded potassium cyanide in the presence of diff erent ions such as magnesium, nickel, cobalt, iron, chromium, arsenic and zinc, in variable concentrations (0.1, 0.25 and 0.5 mM) and as a result the amount of the bacteria in the biodegradation media decreased with the increase of ion concentration. Lastly, it was also observed that sterile crude extract of K. pneumoniae strain degraded potassium cyanide on the fi ft h day of incubation. Based on these results, it is concluded that both culture and sterile crude extract of K. pnemoniae will be used in cyanide removal from diff erent wastes.

“…(Pereira et al 1996;Barclay et al 2002;Santos et al 2013), with several studies establishing sustainable biological processes using bacterial strains including Klebsiella sp., Pseudomonas sp., and Bacillus sp. (Kao et al 2003;Luque-Almagro et al 2005;Chen et al 2008;Mekuto et al 2013). Although these biological processes have been found to be inexpensive and environmentally friendly (Potivichayanon and Kitleartpornpairoat 2014), their use on a large scale is hampered by nutrient requirements needed to sustain the performance of such processes.…”

The kinetics of free cyanide biodegradation were investigated under simulated winter (5 °C) and optimum conditions (22 °C and pH of 11) using a Fusarium oxysporum isolate grown on Beta vulgaris waste as a sole carbon source in the presence of heavy metals, i.e. As, Fe, Cu, Pb, and Zn. The highest free cyanide degradation efficiency was 77% and 51% at 22 °C and 5 °C respectively, in cultures containing free cyanide concentration of 100 mg F-CN/L. When compared with the simulated winter conditions (5 °C), the specific population growth rate increased 4-fold, 5-fold, and 6-fold in 100, 200 and 300 mg F-CN/L, respectively, for cultures incubated at 22 °C in comparison to cultures at 5 °C; an indication that the Fusarium oxysporum cyanide degrading isolate prefers a higher temperature for growth and cyanide biodegradation purposes. The estimated energy of activation for cellular respiration during cyanide degradation was 44.9, 54, and 63.5 kJ/mol for 100, 200, and 300 mg F-CN/L cultures, respectively, for the change in temperature from 5 to 22 °C.
