Anaerobic treatment of agricultural residue based pulp and paper mill effluents for AOX and COD reduction
Ali, Muna; Sreekrishnan, T R (2000)Black liquor and bleach effluent from an agroresidue based pulp and paper mill were treated anaerobically to reduce their high chemical oxygen demand (COD) and adsorbable organic halide (AOX) contents. Addition of 1% w:v ... -
Aquatic toxicity from pulp and paper mill effluents:a review
Ali, Muna; Sreekrishnan, T R (2001)Effluents from pulp and paper mills are highly toxic and are a major source of aquatic pollution. More than 250 chemicals have been identified in effluents which are produced at different stages of papermaking. Their toxic ... -
Effect of cysteine on methionine production by a regulatory mutant of corynebacterium lilium
Dharmendra Kumar; Subramanian, Kartik; Bisaria, Virendra S; Sreekrishnan, T R; Gomes, James (2005)The production of methionine by submerged fermentation using a mutant strain of Corynebacterium lilium was studied to determine suitable conditions for obtaining high productivity. The mutant strain resistant to the ... -
Effect of seed culture on solid-state bioconversion of wheat straw by phanerochaete chrysosporium for animal feed production
Basu, Shubhayu; Gaur, Rajneesh; Gomes, James; Sreekrishnan, T R; Bisaria, Virendra S (2002)The solid-state bioconversion of wheat straw by Phanerochaete chtysosporium for the produc-of animal feed was studied. This study was performed based on central composite experimental design.The conditions of the seed ... -
Effect of sulfur concentration on sludge acidification during the ssdml process
Sreekrishnan, T R; Tyagi, R D; Blais, J F; Meunier, N; Campbell, P G C (1996)Heavy metals present in sewage sludges can be leached out, among other processes, by a process using a consortium of sulfur oxidizing bacteria. The metal leaching could be combined with aerobic sludge digestion to result ... -
Production of methionine by a multi-analogue resistant mutant of corynebacterium lilium
D Kumar; Garg, S; Bisaria, V S; Sreekrishnan, T R; Gomes, J (2003)Multi-analogue resistant mutants of Corynebacterium lilium were developed using UV and N-methyl-N,-nitro-nitrosoguanidine (NTG) mutagenesis in order to overproduce methionine. Although the methionine yield at each stage ...
