Abstract

The present work was designed to investigate the fungal
endophytes of some Egyptian plants irrigated with industrial
waste water as a new biosorbent of cadmium, copper and lead.
The study included the following items:
1- Collecting samples of industrial waste water effluents from a
certain factories.
2- Analysis of these industrial waste water samples to determine
the type of metal ions.
3- selecting of some plants grow in contaminated area, which
irrigated by industrial waste water.
4- Isolation of some fungal endophytes of these plants.
5- Determination of cadmium, copper and lead tolerance of
endophytic fungi.
6- Screening the uptake capacities of various selected metal ions
by these endophytic fungi from industrial waste water.
7- Determination the biosorption of the selected metal ions after
the treatment.
8- Identification of the selected fungal endophytes.
9- IR measurements.

Summary
The obtained results could be summarized as follows:
1- Different industrial waste water samples were collected from
different companies of different industries in Egypt such as
food (Green Land Co., Halwany Co. and Bisco Misr Co.),
painting(Sipes Co.), pharmaceuticals (Gedco Co.) , service
(Cairo International Air Port Co., central and middle
workshop) and water valves industries (Jacop Delafon Co.)
which are drained on sewage waste water as well as
packing materials (Misr pack Co.), (Infit, International Co
for casting & fitting Co.) and cartoons and inks industries
(El-Baddar Co.) that drained on underground water were
contain different harmful concentrations of copper,
cadmium and lead. These water samples proved to be the
best source for cadmium, copper and lead ions.
2- All selected biosorbent plants were collected from garden of
fruits in industrial region located at Gisr El Suez area
irrigated by the industrial wastewater of (El-Baddar Co.)
factory. The highest number of endophytic fungal isolates
were recorded from Rhamnus sp. (Monacrosporium
elegans, Penicillium duclauxi and Curvularia lunata). And
from Saccharum sp. (Rhizopus oryzea, Aspergillus
luchuensis and Aspergillus tubingensis) followed by Morus
alba (Drechslera hawaiiensis and Verticillium Fungicola),
- 194 -
Summary
Morus rubra (Penicillium lilacinum) and Ricinus communis
(Pestalotiopsis clavispora).
3- All endophytic fungal strains under study showed cadmium,
copper and lead tolerance with varying level as evident by
the minimum inhibition concentration (MIC) values of
these metals.
As noticed by the highest MIC reported for isolated strains; it
was Curvularia lunata and Penicillium lilacinum toward
copper, Monacrosporium elegans and Rhizopus oryzea
toward cadmium with Penicillium lilacinum and
Drechslera hawaiiensis toward lead. Data supported
Penicillium lilacinum as potent multi-metal resisted fungus.
4- The biomass of the endophytic Rhizopus oryzea,
Monacrosporium elegans, Penicillium duclauxi,
Aspergillus luchuensis and Penicillium lilacinum supported
the highest uptake of cadmium. The biomass of the
endophytic fungi Penicillium lilacinum, Drechslera
hawaiiensis and Pestalotiopsis clavispora were the best in
copper uptake. On the other hand, Drechslera hawaiiensis,
Penicillium lilacinum, Monacrosporium elegans and
Penicillium duclluxi supported the highest uptake of lead.
Due to Penicillium lilacinum and Drechslera hawaiiensis
exhibited the highest removal of copper and lead with good

Summary
removal of cadmium they were selected for further studies
as the most promising biosorbent strains.
5- Two isotherm equations have been tested in the present
study, namely Langmuir and Freundlich equations. The
Langmuir and Freundlich constants have been calculated
from the corresponding plots for biosorption of Cd ions ,
Cu ions and Pb ions ions on the biosorbents (Penicillium
lilacinum and Drechslera hawaiiensis). The Langmuir
model was able to describe the experimental equilibrium
data for biosorption of Cu ions , Cd ions and Pb ions ions
on fungal biomass Penicillium lilacinum and Drechslera
hawaiiensis under given experimental conditions (biomass
weight equal to 30 mg, pH 2 and 3 hrs contact time ). The
values of KF in Freundlich isotherm model for Cu ions , Cd
ions and Pb ions ions by Penicillium lilacinum and
Drechslera hawaiiensis were determined. Data shows the
highest value of n (The other Freundlich constant) in the
case of Pb ions , which indicating that lead metal ion is
favorably adsorbed by the biosorbents than Cd ions or Cu
ions .
6- Removal and uptake of cadmium by Drechslera hawaiiensis
and Penicillium lilacinum was studied in batch experiments
at varying pH values ranging from pH 2 to 8.
- 196 -
Summary
a) Acidic pH below 4 was not fit for Cd ions removal by
Drechslera hawaiiensis. There was a correlation
between the pH and the time of biosorption process, PH
4.0, 6.0, 7.0 and 8.0 exhibited 100 % removal of Cd
ions after process time of 1440, 120, 120 and 10 min,
respectively.
b) Acidic pH below 4 was not fit for Cd ions removal by
Penicillium lilacinum. pH 6.0, 7.0 and 8.0 exhibited
100 % removal of Cd ions after process time of 180, 30
and 30 min. Data clearly indicated that alkali pH (8) is
favorable for Cd ions removal by Penicillium lilacinum
so in this study we supported alkali pH for the best
removal of cadmium by Penicillium lilacinum.
7) Removal and uptake of copper by Drechslera hawaiiensis and
Penicillium lilacinum was studied in batch experiments at
varying pH values ranging from pH 2 to 8.
a) Removal of Cu ions by Drechslera hawaiiensis was
increased with increasing pH. pH 2.0, 4.0, 6.0 and 7.0
exhibited 100 % removal of Cu ions after process time of
1440, 1440, 180 and 180 min. Data clearly indicated that
neutral pH (7) is favorable for Cu ions removal by
Drechslera hawaiiensis so in this study we supported

Summary
neutral pH for the best removal of Copper by Drechslera
hawaiiensis at the shortest time.
b) Penicillium lilacinum exhibited 100 % removal of Cu ions
at pH 6 after 120 min of treatment. There was a
correlation between the pH and the time of biosorption
process need for 100 % removal. PH 6.0, 7.0 and 8.0
exhibited 100 % removal of Cu ions after process time of
120, 120 and 120 min. Data clearly indicated that pH (6)
is favorable for Cu ions removal by Penicillium
lilacinum.
8) Removal and uptake of lead by Drechslera hawaiiensis and
Penicillium lilacinum was studied in batch experiments at
varying pH values ranging from pH 2 to 8.
a) Acidic pH below 4 was not fit for Pb ions removal by
Drechslera hawaiiensis. pH 2.0, 4.0, 6.0 and 7.0
exhibited 100 % removal of Pb ions after process time
of 1440, 1440, 180 and 180 min. Data clearly indicated
that neutral pH (7) is favorable for Pb ions removal by
Drechslera hawaiiensis so in this study we supported
neutral pH for the best removal of lead by Drechslera
hawaiiensis at the shortest time .
b) Penicillium lilacinum exhibited 100 % removal of Pb
ions at pH 6 after 120 min of treatment. There was a
- 198 -
Summary
correlation between the pH and the time of biosorption
process. PH 6.0, 7.0 and 8.0 exhibited 100 % removal
of Pb ions after process time of 120, 120 and 120 min.
Data clearly indicated that pH (6) is favorable for Pb
ions removal by Penicillium lilacinum.
9- The effect of different cadmium ion concentrations versus
different contact time by Penicillium lilacinum and
Drechslera hawaiiensis was investigated.
a) Drechslera hawaiiensis is a potent biosorbent for cadmium
metal ion from aqueous solution at its lower and higher
concentrations under study of cadmium. The equilibrium
time was detected to be 10 min with 30mg/L and 180 min
with 50, 70 and 90 mg/L to achieve 100% removal but it
was 1440 min contact time to totally removal of 110 mg/L
of cadmium from aqueous solution.
b) The total removal of 10, 30, 50, 70, 90 and 110 mg/L of
cadmium by Penicillium lilacinum was achieved after 1440
min contact time.
So Drechslera hawaiiensis exhibited faster complete removal
of cadmium with the shortest equilibrium time than Penicillium
lilacinum.

in cadmium removal and uptake per unit dry weight of biomass.
