Extracellular phytase production by Bacillus subtilis isolated from the gut of a minor carp, Labeo bata, has been investigated under solid-state fermentation using leaves from four low cost aquatic weeds (Ipomea aquatica, Pistia stratiotes, Lemna major, and Eichhornia crassipes) as substrates. Water spinach, I. aquatica, leaf meal supported maximum phytase activity (15.31 ± 0.38 U/g) and phytate degradation (66.79%). Incubation for 8 days at pH 7 and 35°C temperature revealed optimum phytase production. Maximum phytase production complied with 3.0-mL inoculum size (12.38 ± 0.05 U/g) and 60% initial moisture content (13.46 ± 0.08 U/g). Glucose (10 g/L) and ammonium sulfate (20.0 g/L) supplementation as additional carbon and nitrogen sources yielded maximum phytase production (12.24 ± 0.09 and 17.35 ± 0.06 U/g, respectively). Analysis of fermented leaf meal revealed that there was marginal increase (t-value significant at p < 0.05) in the contents of crude protein, lipid, minerals (Na, K, Ca, Mg, Zn, Fe, Cu, P), free amino acids, and fatty acids; along with reduction in the contents of the antinutritional factors—e.g., crude fiber, tannins, phytic acid, and trypsin inhibitor. The results indicate that there is ample scope for further research to appraise potential application of gut bacteria for sustainable utilization of aquatic weeds as aquafeed ingredients.
