There are several ways to curtail the cost of wastewater treatment. This desire was fuelled in the current study of different composites prepared with modified chitosan by immobilization onto bentonite and silica gel and their characterization by using different sensitive techniques such as FTIR, SEMEDS and TGA. The assessment of synthesized composites was done for its suitability as bioadsorbent characteristics. Silica gel chitosan composite showed peaks at 1082 cm-1, 1316 cm-1 3420 cm-1 and at 3614 cm-1. While, bentonite chitosan composite reveals major peak 1572 cm-1, 3648 cm-1, 3462 cm-1, 1650 cm-1 and 1001cm-1. SEM-EDS study showed their morphology, element composition that correlates the adsorption efficiency. However, TGA study showed their detailed study on thermal stability as more thermally stable compound which is the characteristic feature for adsorption and desorption phenomenon.Keywords

In this study, potential of 30 fungal strains isolated from pulp and paper mill sludge were assessed as biolignolytic microorganisms and their ability to produce ligninolytic enzymes viz., laccase (Lcc), lignin peroxidase (LiP), manganese peroxidase (MnP), xylanase and cellulase using different chromogenic substrates. A total of eight fungi exhibited conspicuous halos with their respective substrate. The fungal isolates were found to be significantly different in qualitative enzyme production. Maximum enzyme activity for Lcc, MnP and LiP were 26.24, 8.5 and 12.99 U/mL exhibited by fungal isolates Trametes sp. (LDFD5), Nigrospora sp. (LDF00204) and Alternaria sp (LDFD4) on 10th and 13th day, respectively, by solid state fermentation (SSF). Conspicuous reduction in colour unit upto 75.29 % and 76.37 % were observed by fungal strain LDF00204 at 30°C temperature and pH 5 respectively. Results depicted that fungal isolate Nigrospora sp. LDF00204 (Accession No. KP732542) exhibited a relatively noble characteristic of having ligninolytic enzymes, is able to degrade lignin and its cocompounds efficiently, and thus it could be utilized for decolorization of pulp and paper mill effluent and also for bioremediation of alike pollutants.Keywords
