KAUST finds chemical alternatives for agarwood perfume production
Researchers seeking environmentally-friendly solutions for fragrance industry
Demand for ingredients from agarwood trees has increased risk of deforestation

RIYADH: Researchers at King Abdullah University of Science and Technology have discovered chemically produced alternatives for ingredients normally sourced from agarwood trees for the production of perfumes in this $44 billion market.
The KAUST researchers published the study, titled “A synthetic biology and green bioprocess approach to recreate agarwood sesquiterpenoid mixtures,” in the journal Green Chemistry on March 4, the Saudi Press Agency reported on Wednesday.
Several types of perfumes use essential oils and other extracts from agarwood, a family of trees found mainly in Southeast Asia. The only natural way to obtain these aromatic substances is by tapping the trees and the high demand for these products has put many tree species at risk of extinction.
The study, conducted by the Sustainable & Synthetic Group at KAUST, examined 58 agarwood samples to identify nine key structures of sesquiterpenoids, one of the main aromatic compounds of agarwood. They then designed a metabolic architecture that enables algae to produce these key structures.
They were able to achieve a yield that is 25 times higher than the ones previously recorded by adopting this new algae-engineered method.
The study showed that the use of metabolic engineering in algae to produce aromatic sesquiterpene compounds had an unexpected effect that improved the production of terpenes by the algae. Some compounds produced by the metabolically-modified algae have potential in drug development, but fragrance is a favored initial commercial target.
In this research study, a new bioprocess was designed to synthesize 103 types of sesquiterpene aromatic compounds from basic structures. It is based on an energy-efficient nanofiltration step for product concentration.
Unlike previous efforts in this field, the entire process can operate at room temperature and produces minimal waste, making it an inexpensive and environmentally friendly process for an industry that relies heavily on dwindling natural resources, the study stated.
The study concludes that any laboratory equipped with basic chemical infrastructure can conduct these experiments.
Saudi Cabinet condemns Israeli comments on Al-Aqsa, seeks end to Gaza humanitarian catastrophe
Updated 28 August 2024
Arab News
RIYADH: Saudi Arabia’s Cabinet on Tuesday expressed its absolute rejection of extremist and inflammatory Israeli statements and condemned continuous provocations against the feelings of Muslims around the world.
It called on the international community to put an end to the Palestinian humanitarian catastrophe, and to activate serious mechanisms to hold Israeli officials accountable for the ongoing violations of international laws, norms and resolutions.
On Monday, Israel’s hard-line Security Minister Itamar Ben-Gvir said, in a radio interview, that he would back the establishment of a synagogue at Al-Aqsa mosque and to have Jews pray at the holy site in Jerusalem.
During the weekly Cabinet meeting, which was chaired by Crown Prince Mohammad bin Salman in Riyadh, the ministers tackled results of meetings held in Switzerland aiming to take concrete and immediate steps to alleviate the suffering of the Sudanese people and achieve a permanent halting of hostilities.
Talks on the war in Sudan were co-hosted last week by Saudi Arabia and Switzerland, with the African Union, Egypt, the UAE and the UN completing the so-called Aligned for Advancing Lifesaving and Peace in Sudan Group (ALPS).
The meetings ended Friday without a ceasefire but with progress on securing aid access on two key routes into a country facing one of the world’s worst humanitarian crises.
The Cabinet stressed that the Kingdom will continue to work with its partners in the international community until security and stability return to the African country.
On the domestic front, the ministers hailed the 10.5% increase in non-oil exports in the second quarter of this year, compared to the same period in 2023.
Saudi Arabia’s non-oil exports surged by 10.5 percent year-on-year in the second quarter of 2024, led by outgoing shipments to the UAE and China, official data showed.
According to the General Authority for Statistics, of the SR51.16 billion ($13.63 billion) registered by the sector in the three months to the end of June, non-oil goods worth SR15.07 billion were sent to the Kingdom’s Gulf neighbor, with SR7.08 billion going to the Asian powerhouse.
The Cabinet also praised the success of the first Esports World Cup, which embodies the efforts made to enhance the Kingdom’s position as a global destination for major sporting events and activities.
On behalf of King Salman and following the meeting, the Crown Prince received newly-appointed Saudi ambassadors to various countries, who took oath of office.

Prophet’s Mosque calligrapher describes ‘unbelievable’ life in Madinah
Three works by Pakistani artist Shafiq Uz-Zaman Khan hang in Al-Rawdah Al-Sharifa
Updated 27 August 2024
SALEH FAREED
JEDDAH: Nearly 55 years ago, a young Pakistani calligrapher embarked on a captivating journey to master the Islamic art form of calligraphy. Today, his work adorns the walls of the Prophet’s Mosque in Madinah.
Shafiq Uz-Zaman Khan, known in Saudi Arabia as “Al-Haram Calligrapher,” is proud that his journey into calligraphy, which began in childhood, brought him to the second holiest and largest mosque in the world.

“In my childhood I used to write on the walls of my house, other houses on our street, on school notebooks and the covers of my brothers’ books. I had a passion for beautiful handwriting,” he told Arab News.
Khan, who has lived in the Kingdom for 45 years, said coming to Madinah was the probably the greatest thing happened in his life: “I spent half of my life in Madinah and wish to live the rest of my life there.”
HIGHLIGHTS
• Shafiq Uz-Zaman Khan, known in Saudi Arabia as ‘Al-Haram Calligrapher,’ is proud that his journey into calligraphy brought him to Madinah.
• He was awarded the President’s Award for Pride of Performance in Pakistan, considered the highest literary award given by the state.
• He finds a peace while doing calligraphy in Madinah that he has not discovered anywhere else, he said.
He continued: “Living in Madinah and at the same time being the calligrapher of the Prophet’s Mosque … that’s unbelievable.”

Born in Rawalpindi and raised in Karachi, the 68-year-old’s passion for calligraphy was ignited while painting signboards for shops around the Pakistani capital to earn a modest living.
I was happy to move to the place that I dreamed of since I was young and the most important thing for me was just to be close to the Prophet’s Mosque.

In 1979, a Saudi businessman visiting Karachi saw some of Khan’s paintings and engaged him to work at the company he owned in Riyadh. After proving his prowess as a calligrapher in the advertising industry, he was offered a job in Madinah.
“Despite my good status in Riyadh and the great relationship I had with my sponsor, I was so happy to move to the place that I dreamed of since I was young and the most important thing for me was just to be close to the Prophet’s Mosque,” said Khan.
“In 1991, the management of the Prophet’s Mosque announced a competition to choose a calligrapher to restore the Qur’anic writings in the mosque dating back to the Ottoman era. I decided to enter the competition, but the organizing committee refused my registration because I was not a professional calligrapher and also my native language was not Arabic, and they thought it would be hard to compete against other Arab calligraphers.”

Khan managed to convince the organizing committee that his skills and passion for his craft meant he should be given a chance. He went on to win the contest.
“There were calligraphers from Egypt, Syria, Jordan, Iraq and other Arab countries but I was confident and was so happy to be selected as the winner,” said Khan.
His work did not stop at restoring the existing writings and verses. He was assigned to write in a number of domes in the Haram, combining “revitalizing ancient writings with the implementation of new calligraphic paintings.”
He was also entrusted with writing new plaques for several chapters, including the Chapter of Peace, the Chapter of Abu Bakr al-Siddiq, the Chapter of Mercy and the Chapter of Gabriel.
“All the works that I executed carry the same importance, whether they are the Qur’anic paintings that I executed in a number of domes, on the walls, or the names of the doors. This place is unusual for every Muslim, and it was an honor for me to work there,” he said.
After completing calligraphy on the 177 domes, he received positive feedback on his work. One dome takes approximately two months to complete, including the design and implementation.
Three of Khan’s paintings hang in Al-Rawdah Al-Sharifa, each of which are made of 24-karat gold and took six months of work.
The calligrapher enjoyed a proud moment when the President of the General Presidency for the Affairs of the Two Holy Mosques, Sheikh Abdulrahman bin Abdulaziz Al-Sudais, honored him for his efforts and proficiency.
“It was unforgettable moment for me … I will always cherish it,” he said.
Khan has also won several competitions at national and international level and was awarded the President’s Award for Pride of Performance in Pakistan, considered the highest literary award given by the state.
