I am very happy to be with you this evening

Opera.

I am from Fez,

The spiritual and cultural capital of Morocco.

I’ll take you there:

Where millions of tourists visit

To discover its ancient city,

Which dates back more than 1200 years.

And also to discover its antique character:

Paper mills, pottery and textile production.

but unfortunately,

These crafts secrete a lot of waste,

In addition to industrial and domestic waste.

We have been observing for years

Primary symptoms of this pollution.

Especially in Wad Sabo,

Which is considered an important guide in Morocco

Especially in Fez,

It tells the crops

It provides potable water

Population and animals in the region.

These trades, these industries

Bear a large part of the responsibility for pollution of our surroundings,

But each of us bears part of the responsibility.

Because we are constantly contributing

Toxic substances in our environment,

Which contribute to pollution

And may pose a risk to our health.

The problem of toxic substances –

I mean here the synthetic toxic substances,

From chemistry,

Which we may know or not

And also natural toxic substances.

Calcinidates.

Everyone knows cyanides;

But do you know that it is made by bacteria,

They also exist in fruit seeds?

Such as grapes, apples –

It is also found in almonds.

All you need is 6 milligrams of cyanide to kill you

In other words,

If you eat fifty almonds a day,

It is very likely that you have died of cyanide poisoning

And again the problem of toxic substances:

Is that a small amount is poorly concentrated

Have a direct impact on your health.

Some of these products degrade easily

And quickly:

Some do not decompose.

And even simplify the concept more

Imagine plastic bags with me.

Yes, yes, the plastic bags you use every day

It is practical, easy to use and inexpensive

And appear harmless.

But we are not fools:

We all know that these bags take a long time to decompose.

Hundreds of years.

This is what we want to bring to our children,

And future generations.

And that’s what prompted me.

In this context, I began to develop a research message.

In addition to some questions.

How can I contribute to this battle

Against the pollution of my environment?

How can we stop the accumulation of these substances,

And how can we get rid of them?

Traditional solutions rely on purification centers.

But limited.

And there is a defect.

And increasingly with each year.

Why this imbalance?

There are many reasons, but most prominent

Because of the water,

Which, for example, are in large quantities such as flooding

Or because it has a lot of pollution.

In both cases, the water will pass on several filter stations,

By removing it from the largest pollutant.

Car wheels, shoes

And plastic bags.

Then we leave him alone

Of small particles by gravity.

And then it remains to get rid of the small remains:

Which we do not see with the naked eye,

Microorganisms, heavy metals, toxic products.

By adding chlorine.

If necessary, the addition of chemical disinfectants,

So we do not solve the problem;

As far as we only carve.

Just as plastic bags are stacked in nature,

Also accumulate chemicals in water.

And therefore we are surrounded,

Whether when we pollute or clean,

By toxic substances.

So can we get out of this vicious circle?

This is the core of your research.

The solution:

To be inspired by my research of nature,

For an alternative to these toxic substances.

Mainly because

If we use materials that degrade easily,

We can reduce pollution

If less effort to clean.

If, find an alternative to these toxic substances,

So that artisans and industries can continue production,

And continue to use industrial processes

Which works well

So they do not find themselves with a huge amount of stacks and pollution.

These methods are used in crafts and industrial sector

Too bad.

Are aggressive ways.

In terms of heat, in the vicinity, salty

Essential, or acidic, at the same time,

And since I want to draw my thoughts from nature,

And you have the right to say, today: “But Laila,

Any structure you can live

In these circumstances? “

In very violent circumstances?

And this is great because in nature

There are precise objects capable of

Resist these unreasonable circumstances.

We call it: micro-organisms.

As for my research,

It has focused on bacteria, then saline plants,

With very high resistance to salt concentration,

And there are those who need this salt to live,

For development, for growth.

In addition to being very special,

These bacteria secrete enzymes

If, enzyme,

It is a large molecule that analyzes all types of products.

And we also make enzymes

In the mouth and this helps us in the analysis of eating,

And also at the level of the stomach, helps digestion.

These enzymes can be used in everything

Because, on the one hand, lies the usefulness of these enzymes,

In it molecules are active in all conditions

Just like saline bacteria that resist harsh conditions

On the other hand, it decomposes easily,

And do not accumulate.

Best of all,

These enzymes are in good condition and can be reused.

They are therefore perfect elements

With this kind of cooperation

Which was limited only to toxic substances.

But to wait a little,

Make sure that all the conditions are favorable and must ask good questions

Find bacteria and good enzymes

In particular, think about the consequences.

So what are good bacteria?

Are non-pathogenic bacteria:

It should not affect your health.

And must be of good performance,

To be used by industries in their operations.

In the last,

Enzymes that are manufactured

Should perform a good job during operations.

Where do we find them?

in nature.

But not anywhere.

For example, they were found in salt mines in Fez.

And also in saline hot springs.

And that’s what helped me today

Collect more than 200 samples of saline bacteria

Which excretes all kinds of different enzymes,

And able to combat any kind of different problems

These enzymes are produced by microorganisms and saline bacteria,

Can be used in many complex industrial processes,

Such as paper conversion, food,

Or biological processes and washing processes.

More specifically, we can replace

Washing powder and detergents,

Under the name of Burberry:

Betoxiatanol -2.

It is a clean chemical cleaning product

It even causes some people infections

Sensitivity and complications are more serious.

Such as blood and kidney disorders.

If we can replace them with enzymes

Which will not affect our skin,

You will only attack the spots on your clothes.

In very specific circumstances,

As in the washing machine.

All this is very promising.

But…

This is the “but” damned

Is economic.

I swear that you were not surprised

Today it costs five times more

The use of bacteria enzymes,

On the use of products currently available in the markets.

We are still in the research stage.

And research in Morocco

So you can face these multiple problems,

Using simple solutions,

Because of limited possibilities.

These constraints create new opportunities for us.

This allowed me, for example,

Producing an enzyme from bacteria

Simple Possibilities.

And as evidenced by his name, it is a water,

A little salt and some minerals.

At room temperature.

Do you realize?

It does not cost anything.

The statement of Jalal al-Din al-Roumi,

Which summarizes well all these constraints and opportunities

Enter the moonlight to let the room depend on the size of the window

Even if the light of the moon overflows through the horizon in the sky

And here opened a window:

Horizon possible.

I fully realize that the road is still long

So that the idea is applied directly to the industrial sector

Yet I am confident.

Because who knows, maybe our universities

You will find the best solutions to our problems,

And your problems as well.

Thank.
