Evaluation of anti-bacterial potential of protein isolated from the muscle
of Channa striatus
Keywords:
Channa striatus, Anti-bacterial activity, MIC and MBC.
ABSTRACT:
Protein was extracted from muscles of Channa striatus and attempts were
made to evaluate in vitro antibacterial activity against clinical bacterial isolates. The
higher concentration of protein (100µg/ml) extracts exhibited a pronounced activity
against Pseudomonas aeruginosa (21 mm), Proteus vulgaris (19 mm), Citrobacter sp
(19 mm), Klebsiella pneumoniae (18 mm), Micrococcus sp (17 mm), Bacillus subtilis (16
mm), Staphylococcus aureus (15 mm), E. coli (14 mm) and Serratia marcescens (5
mm). The minimum inhibitory concentration and minimum bactericidal concentration
were found to be 20-40 µg/ml and 80-100 µg/ml respectively for the extracts of
Channa striatus protein against test organisms. This study confirms that C. striatus fish
protein extracts possess antibacterial activity against a wide range of microbes and
justified that it could be used in the traditional medicine as a remedy for the
treatment of bacterial diseases.

INTRODUCTION
Fish being the most antiquated type of aquatic
life as a food have been accounted to have a twofold
nutritional benefit of having the capacity to give high
extents of their quality because of the occurrence of
essential amino acids. Furthermore being easily
digestible not like those of meat and other domesticated
animals as a result of low collagen contamination of
natural habitat from modern, household and rural waste
has uncovered these vital aquatic life forms to
contaminants which endanger their lives as well as in the
end enter the evolved way of life prompting serious
health hazards (Ilavazhahan et al., 2010).
Bacterial diseases of extraordinary artifact, has
caused more suffering and death than most pathogens. It
remains a noteworthy medical issue of worldwide
concern (Grange, 1998). The current evaluations propose
that around two billion individuals are infected with
bacterial pathogens, of which 8-10 million create
dynamic diseases with two million deaths every year
(Frieden et al., 2003). Barbosa and Levy (2000) revealed
the extensive use and abuse of anti-biotic are without a
doubt the real foroces related with the high quantities of
resistant pathogenic and commensal microbes around the
world. For diagnostic purposes pure protein derivate is
used to distinguish immune response to the bacterial
antigens (Sujatha et al., 2010). The advancement of
antimicrobial medication protection is a noteworthy
hindrance to infectious disease control. Strategies for
disease prevention, for example, enhanced cleanliness,
anti-microbials and vaccine developments have
demonstrated to be fruitful in controlling numerous
illnesses, however the adequacy of immunizations relies
upon the standing and developing viability of serotypes
in a given populace of bacterial pathogens. Future
disease control depends on the vaccine development
which is often constrained by failure to initiate sufficient
resistant reactions to the full scope of disease causing
serotypes of a specific pathogenic species seen in an
environment (Tekle et al., 2012). Subsequently, there is a
need to distinguish and assess bacterial antigens for the
diagnosis of bacterial disease and to create powerful and
more secure vaccines for replacing allopathic
medications. There are numerous diseases known today
for which no strong vacccines exist, and the utilization of
low efficacy immunizations may really diminish
profitability (Thorarinsson and Powell, 2006).
Therefore, the present study was designed to
study the medicinal use of proteins isolated from Channa
striatus to explain the rationale of its use in traditional
medicine by in vitro assessment. The antibacterial
activities of protein extracts against clinical bacterial
isolates of human pathogenic microorganisms were
studied.
MATERIALS AND METHODS:
One gram of muscle sample was taken from
Channa striatus (Murrel fish) collected from Poondi dam
reservoir, Thiruvallur district, Tamilnadu, India. It was
homogenized with distilled water using mortar and pestle
for the preparation of crude sample. From the crude
protein sample, proteins were isolated by ion exchange
chromatography method (Zhang et al., 2006). Before
starting the separation, an equilibration buffer was
pumped through the column to equilibrate the oppositely
charged ions. Upon injection of the crude protein sample,
solute particles were exchanged with the buffer ions as
every ion would compete for the binary sites on the resin.
The most weekly charged compounds were eluted in the
first place, trailed by those with progressively stronger
charges utilizing elution buffer. Purity of the eluted
protein sample was affirmed by Western blot techniques
(Paulsi and Dhasarathan, 2011).
Anti bacterial testing
Microorganisms employed determining the anti-
bacterial activity of the extract are Escherichia coli,
Pseudomonas aeurogenosa, Bacillus subtilis,
Proteus vulgaris, Klebsiella pneumoniae, Micrococcus

sp, Staphylococcus aureus, Citrobacter sp and Seratia
marcescens which were isolated from the different
patients diagnosed with various wound infections at the
laboratory of Joys Clinical Lab, Manvalanagar,
Thiruvallur, Tamilnadu. The antibacterial activities of
C. striatus fish protein extracts were evaluated in vitro
by disc diffusion method using Muller Hinton medium.
Disc diffusion method
Filter paper disc diffusion method (Garg and
Jain, 1998) was used for analyzing antimicrobial activity.
Whatman No.1 filter paper discs of 6mm diameter were,
set in dry petri plates, and autoclaved. Sterile filter paper
No.1 discs were loaded with the test protein extracts
following Irobi et al. (1996) method. Discs were loaded
with standard antibiotic streptomycin (w/v) in two
various concentrations (20µg/ml and 40µg/ml). The
pathogenic strains were suspended in Muller Hinton
broth (Hi Media) by transferring a loop full of bacteria
grown for 24 h on agar slants. The suspensions were
vortexed and 0.1ml aliquots were spread over respective
agar medium plates. The protein extracts and
streptomycin loaded discs were then kept over the plates
seeded with particular microorganisms. The plates were
incubated at 37ºC for 24 h. The antibacterial action was
determined by measuring the inhibition zone around the
discs.
MIC and MBC test
Minimum Inhibition Concentration (MIC) of the
extracts was resolved from the culture plate that had the
most lowest concentration inhibiting the development of
bacterial strains. Minimum Bacterial Concentration
(MBC) was determined by utilizing the strategy for
Samy and Ignacimuthu (2001). The test containing 3ml
of Muller Hinton broth and 0.1ml of bacterial suspension
and 0.1ml protein extract were incubated at 37ºC for 24
h. Bacterial turbidity was measured at 650 nm to decide
the rate of inhibition of bacterial growth. Streptomycin at
20 and 40µg/ml was utilized as reference for detecting
MBC. The tubes containing just the growth medium and
each of the bacteria were utilized as control. The MBC
indicated decrease the bacterial growth as measured from
the turbidity of the culture examined by optical density
value.
RESULT AND DISCUSSION
The proteins was characterized by Western blot
method. Bands in test lane was compared with standard
protein marker, which shows 136 kDa molecular weight.
The protein extract of C. striatus collected from the
Poondi dam reservoir was found to be effective against
all tested organisms with inhibition zone ranging from 5
to 21 mm in the concentration of 100µg/ml. When,
comparing the result with standard anti-biotic
streptomycin a direct proficiency was recorded (Table 1).
The protein extract of C. striatus collected from the
Poondi dam reservoir showed highest inhibition activity

Channa striatus samples collected from Poondi
dam reservoir had broad spectrum of antibacterial
potential. The minimum inhibitory concentrations of fish
protein, C. striatus was given in Table 2. The results
showed that the minimum inhibitory concentration of
fish protein of C. striatus showed the inhibitory effect
against all test pathogens at the concentration of 20-40
µg/ml onwards.
The minimal bactericidal concentrations of the
protein of C. striatus samples showed the notable effect
on all test pathogens. The minimum bacterial
concentration (80-100µg/ml) of the C. striatus fish
proteins showed effect of pathogenic inhibition in
comparison to those of streptomycin. In vitro
antibacterial test was added to evaluate the viability of
protein extract by inhibiting the growth of pathogenic
organisms with wide range of antibacterial potential.
Gram positive microorganisms and gram negative
microbes like Escherichia coli, Pseudomonas
aeruginosa, Bacillus subtilis, Proteus vulgaris,
Klebsiella pneumoniae, Micrococcus Sp,
Staphylococcus aureus, Citrobacter Sp and Serratia
marcescens demonstrated a decrease in their
development on treatment with the protein extract. The
level of inhibition as measured by the disc diffusion
method, announced that the gram negative bacteria were
more hindered than the gram positive microbes. Similar
findings were also reported by Lighty et al. (2010) in the
extract of red velvet mites.
CONCLUSION
The present study suggested that using protein
extracts of C. striatus fish is cheap and cost effective
drugs can be prepared for bacterial infections. The broad
spectrum of antibacterial activity of C. striatus fish
protein is highly promising for further analysis. The
active fraction obtained from this fish protein is an
attractive material for further studies leading to possible
drug development. This fraction can be used as such for
ethno medicine development with further, studies to
establish safety and efficacy. Improvement of ethno
medicines is generally cheap and less tedious; it is more
