ABSTRACT
This study was aimed to evaluate the production of Cellulase by Aspergillus niger and Trichoderma viridae were isolated and
identified from soil and used for the study. Aspergillus niger and Trichoderma viridae were screened for their cellulase production
ability. Cellulase production was analysed in Agro-industrial waste such as Pineapple peel, Orange peel and Banana peel. From this
study, Aspergillus niger and Trichoderma viridae have high enzyme activity in Pineapple peel. The optimization study was performed
on pineapple peel the optimum parameters for the isolated organism for cellulase production were studied on varying condition
such as P
H
, temperature and substrates concentration (Carbon and Nitrogen). The maximum production of cellulase was noticed at
temperature 25°C, and PH 6, in pineapple peel for Aspergillus niger than Trichoderma viridae Finally concluded that the Aspergillus
niger showed highest level of cellulase production which was recommended for industrial level cellulase production.
Keywords: Cellulase, Agro-industrial waste, Submerged fermentation, Aspergillus niger , Trichoderma viridae.
INTRODUCTION
nzymes are proteins that exhibit catalytic activity.
The enzyme complex molecular structure consists
of one part of protein, but it can be connected to
other molecules such as carbohydrates and lipids.
Enzymes are present in all living cells, which exercise the
function of catalyst of the reactions that compose the
anabolic and catabolic pathway of cellular metabolism.
Cellulase is an important extracellular microbial enzyme,
which hydrolyzes cellulose.
It is also one of the most expensive sources of biomass
utilized for the production of pressing in the fruit juice
industry and other factories via enzyme bioconversion,
which proves to have a high industrial value.
A great number of microorganisms, mostly fungi are able
to degrade cellulose for their growth and produced a
complete set of cellulase for the hydrolysis of cellulose to
soluble sugar.
The agro waste such as pineapple peel, rice straw, orange
peel, Banana peel etc can be used as the best substrate
for bioconversion. Cellulose is commonly degraded by an
enzyme called Cellulase.
This enzyme is produced by several microorganisms,
commonly by bacteria and fungi.
Fungal genera like Trichoderma sp and Aspergillus sp and
are taught to the cellulase producers and crude enzymes
produced by these microorganisms are commercially
available for agricultural use.
Cellulases are enzymes that are capable of breaking
cellulose glucosidic bonds, resulting in the release of
oligosaccharides, cellobiose and glucose.
These hydrolytic enzymes are used in the food,
pharmaceuticals, cosmetics, detergents and textile
industries.
Their main applications include the bleaching of pulp in
the paper industry, the production of dissolved pulp
waste water treatment and recycling of paper residues.
Enzym e technology is currently one of the most
promising new technologies for the synthesis of valuable
compounds.
Industrial processes that employ enzymes in
biotransformation processes have a lower environmental
impact and concomitantly lower consumption of energy,
since they are biodegradable and highly specific which
induce undesirable effects.
Cellulase production depends on the type of substrate,
pretreatment and strain microorganisms used. Cellulase,
it is a multi enzyme complex capable of decomposing
plant substrate.
One component of the cellulase enzymes system is β-
Glucosidase and it work together with endoglucanase and
to break down cellulose in the plant cell walls.
The objective of the present study was to collect the soil
sample for isolation and identification of fungi using
appropriate method, to screen the cellulase producing
fungal strain, to estimate the cellulase productivity using
DNS method and to optimize the media formulation for
the production.
