NITROGEN SOURCES ON TPOMW VALORIZATION THROUGH SOLID STATE FERMENTATION PERFORMED BY Yarrowia lipolytica

The strains capable of degrading cellulose have attracted much interest because of their applications in straw resource utilization in solid-state fermentation (SSF). However, achieving high spore production in SSF is rarely reported. The production of spores from Streptomyces griseorubens JSD-1 was investigated in shaker-flask cultivation in this study. The optimal carbon, organic nitrogen and inorganic nitrogen sources were sucrose, yeast extract and urea, respectively. Plackett–Burman design (PBD) was adopted to determine the key medium components, and the concentration levels of three components (urea, NaCl, MgSO4·7H2O) were optimized with the steepest ascent path and central composite design (CCD), achieving 1.72 × 109 CFU/g of spore production. Under the optimal conditions (urea 2.718% w/v, NaCl 0.0697% w/v, MgSO4·7H2O 0.06956% w/v), the practical value of spore production was 1.69 × 109 CFU/g. The determination coefficient (R2) was 0.9498, which ensures an adequate credibility of the model.

Sugarcane Plant

Gibberellic acid production using Fusarium moniliforme, isolated from wilted sugarcane plant has been investigated by solid state fermentation (SSF). The gibberellic acid production of 154mgm/gm was obtained on commercial wheat bran (CWB) mineral salt acid bed in 500 ml flasks after 168 h incubation. The gibberellic acid production rate was about 0.6 to 0.9 mgm/gm/hr during 96 to 168 h. Different carbon sources namely sucrose, lactose, maltose, soluble starch, glycerol, wheat flour and maize flour were tested as an additional substrate along with CWB at the concentration of 25% w/w or v/w base to observe its effects on gibberellic acid production. Soluble starch has been proved the best additional carbon source for gibberellic acid production, which yielded 1160mgm/gm of gibberellic acid after 168 h. Similarly, various nitrogen sources namely NH4Cl, NH4NO3, (NH4)2SO4, (NH4)MoO4 and urea were tested as an additional substrate at the concentration of 0.07% w/w of CWB. Urea was proved as the best nitrogen source which yielded 532 mgm/gm of gibberellic acid after 168 h incubation. We have observed about 7.5-fold and 3.5-fold increase in gibberellic acid production upon addition of soluble starch and urea respectively, in CWB using Fusarium moniliforme.Int J Appl Sci Biotechnol, Vol 4(3): 402-407

Operational Variables

The production of laccase by solid-state fermentation (SSF) usingArmillariella tabescenswas studied. Wheat bran was selected to be the most suitable solid substrate. Several operational variables including nitrogen source, moisture content, copper and aromatic inducers were investigated. The results showed that the complex nitrogen sources, NH4NO3coupled with peptone was shown to be the best nitrogen source. 75% of initial moisture content was proved to be appropriate. Copper significantly influenced the laccase production and the yield of laccase was improved by addition of 1.5 mM copper sulphate in the medium. Guaiacol efficiently induced the laccase production and the enzyme yield (24500U/g) was enhanced by 32% compared with he control without any aromatic inducers. Efficient production of laccase fromA. tabescenscan be achieved by solid-state fermentation.

Cunninghamella Blakesleeana

Abstract Our earlier paper had established the fact that new soil fungi known as Cunninghamella blakesleeana is potent enough to produce lovastatin significantly. At present, there are no reports on the media optimization for the lovastatin production. Hence, the objective is to optimize the fermentation conditions for lovastatin production by Cunninghamella blakesleeana under Solid State fermentation (SSF) condition through screening the critical factors by one factor at a time and then, optimize the factors selected from screening using statistical approaches. SSF was carried using the pure culture of Cunninghamella blakesleeana KP780148.1 with wheat bran as substrate. Initial screening was performed for physical parameters, carbon sources and nitrogen sources and then optimized the selected parameters through PBD and BBD. Screening result indicated the optimum values of the analysed parameter for the maximal production of lovastatin by Cunninghamella blakesleeana were selected. Out of the nine factors MgSO4, (NH4)2SO4, pH and Incubation period were found to influence the lovastatin production significantly after PBD. The optimal levels of these variables and the effect of their mutual interactions on lovastatin production were determined using BBD surface design. The optimum medium composition was found to be MgSO4(0.2 g/L), (NH4)2 SO4 (12.5 g/L), pH (6) and Incubation period (7 days). Experimental studies showed a yield of 7.39 mg/g at the above optimized conditions which were observed to be very nearby to the predicted value and hence the model was successfully validated. Hence, this is the first report on the optimization of critical parameters for lovastatin production by Cunninghamella blakesleeana.
