Abstract
Indiscriminate disposal of the solid waste generated from various agricultural practices and agro based industries causes detrimental effects in the environment. Utilisation of the waste biomass for the production of value added products through biotechnological intervention not only helps to combat environmental pollution but also adds to the economy. Hence, the present work focuses on integrated production of bioethanol and biomanure from pineapple leaf waste for its complete utilisation leading to zero waste generation. Bioethanol production from pineapple leaf waste was carried out through simultaneous saccharification and fermentation (SSF) by employing cellulolytic enzyme from Trichoderma reesei Rut-C30 and Saccharomyces cerevisiae. The SSF of pineapple leaf waste resulted in bioethanol production of 7.01% (v/v). The residue obtained after bioethanol production was inoculated with five different strains of blue-green algae and their concoction for nitrogen (N), phosphorous (P) and potassium (K) enrichment. Among them, Fischerella muscicola was found to enrich N, P and K content of the residue by nearly 6.84, 8.78 and 14.17 fold than that of the initial content, ultimately leading to improved NPK ratio of approximately 3.5:1:2. The efficient conversion of pineapple leaf waste to bioethanol and enrichment of residue obtained after SSF for its application as biomanure envisages environmental sustainability.
