Scientists find natural food preservative from bacteria

[vc_row][vc_column][vc_column_text]By Bhavya Khullar

Outbreak of food-borne pathogens can cause havoc. Now Indian scientists have found a solution – a bacterial protein isolated from intestine of chicken. They say it can be used as a food preservative since it can prevent growth of agents that cause food poisoning.

This research has been conducted at the School of Life Sciences at Pondicherry University,. The researchers have obtained the natural food preservative from Enterococcus  faecalis CV7 bacteria which were isolated from intestines of country chicken. Researchers cultured these bacteria in the lab under controlled conditions and isolated a short protein named bacteriocinCV7.

“BacteriocinCV7can be used as a natural food preservative, as we have seen that it inhibits the growth of Salmonella, a causal agent of food poisoning,” explained Arul Venkatesan, who conducted the study along with Venkatesh Perumal. “The demand for natural food preservatives has dramatically increased amongst consumers owing to the need for healthy, safe, and fresh products.”

The research results have been published in the journal Food Science and Technology.

Studies showed that BacteriocinCV7 remained functional even at high temperatures of 90 degree Celsius and killed disease-causing microbes in food in less than 18 hours even at a low concentration of 1 gram per liter. Therefore, using bacteriocinCV7 can reduce use of synthetic preservatives and make food safe for consumers, said Venkatesan.

In addition, he said, bacteriocinCV7 can also be used as a probiotic for poultry to control infections in place of synthetic antibiotics. This will make food safe for humans in the long run. The scientists have found that bacteriocinCV7 is non-toxic and safe by testing it on cultured human cell lines.

PM Modi hails ISRO after successful GSLV-F17 launch, calls it proud moment

PM Modi congratulated ISRO after GSLV-F17 successfully launched EOS-05, calling the achievement a proud moment for India.

Prime Minister Narendra Modi on Friday congratulated the Indian Space Research Organisation (ISRO) after the successful launch of the GSLV-F17 rocket carrying the EOS-05 Earth observation satellite, describing the achievement as a proud moment for the nation.

The GSLV-F17 lifted off at 2:55 a.m. IST from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The EOS-05 satellite was subsequently placed into its designated sub-geosynchronous transfer orbit.

PM Modi praises ISRO’s growing capabilities

In a post on X, PM Modi said the successful mission reflected the excellence, innovation and expanding capabilities of India’s space sector.

He also highlighted the growing partnership between ISRO and Indian industry, saying it was strengthening India’s space programme and expanding capabilities across the wider space ecosystem.

The prime minister described the successful launch of GSLV-F17 carrying EOS-05 as another outstanding achievement by ISRO and a matter of national pride.

EOS-05 strengthens earth observation capabilities

According to the report, EOS-05 is India’s first-ever imaging satellite from geosynchronous orbit. The satellite is designed to provide continuous observation of the country from an altitude of nearly 36,000 km above Earth.

The mission is expected to strengthen India’s earth observation capabilities and support advanced imaging and observation applications.

ISRO Chairman Dr V Narayanan expressed satisfaction with the mission, saying the satellite was precisely injected into its intended orbit.

Mission Director Thomas Kurian described the launch as a significant milestone for the GSLV programme. He said it was the 19th flight of the GSLV and noted that EOS-05 is the heaviest satellite the launch vehicle has placed into a geosynchronous transfer orbit or sub-GTO orbit.

GSLV-F17 launch vehicle details

The GSLV-F17 stands 51.7 metres tall and has an approximate liftoff mass of 420.5 tonnes.

Science and Technology Minister Jitendra Singh also congratulated the ISRO team following the successful mission. He described EOS-05 as a state-of-the-art Earth observation satellite capable of advanced imaging across visible, infrared, multispectral and hyperspectral bands.

Indian-origin NASA astronaut Anil Menon has embarked on his first journey into space after successfully launching aboard Russia’s Soyuz MS-29 spacecraft to the International Space Station (ISS).

The mission lifted off from the historic Baikonur Cosmodrome in Kazakhstan at 8:17 PM on Tuesday. Menon was accompanied by Russian cosmonauts Pyotr Dubrov and Anna Kikina as the three-member crew began their expedition to the orbiting laboratory.

Crew to spend about eight months aboard ISS

The Soyuz MS-29 spacecraft is expected to dock with the International Space Station a little over three hours after launch. Once aboard the ISS, the crew will carry out a range of scientific research and technology demonstration projects during their mission.

The expedition is scheduled to last approximately eight months, with the crew expected to return to Earth in 2027 after completing their planned activities in orbit.

Menon’s maiden spaceflight marks a significant milestone in his astronaut career as he joins the International Space Station crew for long-duration research and operational work.
