Upgrading of distillery effluent by Nitrosococcus oceanus for its use as a low-cost fertilizer

Wastewater treatment in molasses-based alcohol distilleries for COD and color removal: A review

“…Nearly 76% decolorization, which is possibly due to a sugar oxidase, has been observed. The nitrifying bacteria Nitrosococcus oceanus is capable of detoxifying the spentwash accompanied by a reduction in the chloride content (Arora et al, 1992). However, no explanation was provided for this observation.…”

A review of microalgae and other treatment methods of distillery wastewater

“…Bacillus megaterium and Bacillus cereus were also used to remove both COD and colour by 81 and 75%, respectively, from predigested distillery effluent (Jain et al , 2002). Acetogenic bacteria have oxidation capability to oxidize and decompose melanoidins in DW while nitrifying bacteria Nitrosococcus oceanus detoxify and reduce chloride concentration of spent wash (Arora et al , 1992). Application of bacteria (microbial) biotechnology in wastewater treatment provides economic and ecological benefits.…”

Plant-available inorganic nutrient levels are increased in rice-derived distillery effluents inoculated with microbes

“…Previous studies revealed that the application of untreated distillery effluents to mung beans ( Vigna radiata ) and rice ( Oryza sativa L.) suppressed seed germination and seedling growth, suggesting that pretreatment of the effluent to degrade organic matter before application to crops might yield better results (Arora et al . ; Kannan and Upreti ).…”

“…Although some studies have assessed the effect of biodegraded distillery effluent on crop growth, the effect of inoculation of various microbial strains on the production of inorganic plant nutrients in effluents has not been investigated (Arora et al . ; Ramana et al . ).…”
