Description |
A study was carried out to customize enzymes specific to whole cotton seed and tapioca flour while simultaneously exploring the possibility of producing these customized enzymes at farm gate level using Trichoderma viridae on paddy husk by solid state fermentation. Whole cotton seed was rich in crude protein (19.31± 0.17%) and ether extracts (14.73 ± 0.97%) while tapioca flour was rich in crude fibre (15.45±7.22%) and soluble carbohydrate (78.27±7.01%) content. Hemicellulose was higher in tapioca flour than that of whole cotton seed. The per cent glucan, xylan and arabinan in tapioca flour and whole cotton seed were 27.67 ±1.62, 29.40 ±0 .45 and 24.19 ± 1.78 % and 17.49 ± 0.72, 17.45 ± 1.39 and 18.71 ± 1.29 % respectively. The respective levels of individual enzyme viz. cellulase, xylanase, glucanase, pectinase and amylase identified for whole cotton seed and tapioca flour were 46.0, 28.0, 1.5, 2.0 and 9500 (U/g) and, 21.0, 18.0, 0.6, 16.0 and 12000 (U/g). The additive effect of these enzyme when combined as mixture was studied by including five treatments each with six replications in completely randomised design to arrive at the “customized enzyme mixture” for tapioca flour as 20.63 U of cellulase, 19.25 U of xylanase, 20.63 U of glucanase and 20.0 U of pectinase and 10800 U of amylase and was referred as “Customised enzyme mixture for tapioca flour”, while there was no additive effect for whole cotton seed and the “Customised enzyme mixture for whole cotton seed” was determined to be 46 U of cellulase, 49.6 U of xylanase, 46 U of glucanase and 42.2 U of pectinase and 9500 U of amylase. The second experiment for enzyme production by solid state fermentation on unground / ground paddy husk with / without culture media supplementation was designed with four treatments of six replicates in each and lead to inconclusive results. However, it was noticed that even when Trichoderma viridae was inoculated on unground paddy husk, the enzyme production was reasonably good and therefore further investigation on Trichoderma viridae inoculated unground paddy husk with or without media supplementation was carried out since it is easier to adopt at farm gate. An in vitro degradability trial using crude enzyme extract from unground paddy husk supplemented with or without media revealed a significant (p |
