Washing does not remove Salmonella bacteria from tomatoes, IISc team finds

IISc researchers have found that tomatoes get infected with Salmonella typhimurium, which cause gastroenteritis, when the bacteria enter the plant through tiny openings that form on the main root for the lateral roots to emerge. Hence, the bacteria are found inside tomatoes and cannot be removed by washing. As salinity increases the number of lateral roots … Continue reading Washing does not remove Salmonella bacteria from tomatoes, IISc team finds

Podcast: Removing oil from water using aloe vera

Uttam Manna of IIT Guwahati explains how his team synthesised an extremely oil-repelling (super oleophobic) membrane using an aloe vera gel-based coating modified with some molecules to remove oil from water. The membrane could be reused at least 25 times to separate light and heavy oil from water with the efficiency of separation remaining above … Continue reading Podcast: Removing oil from water using aloe vera

IIT Guwahati uses aloe vera to remove oil from water

IIT Guwahati researchers have synthesised an extremely oil-repelling (super oleophobic) membrane using an aloe vera gel-based coating modified with some molecules. This is the first time a naturally occurring material has been used for the said purpose. The membrane could be reused at least 25 times to separate light and heavy oil from water with … Continue reading IIT Guwahati uses aloe vera to remove oil from water
