Next-generation Biofilm microbial ameliorators

Inbound Scholar Exchange on the Soil Biology and Health

Soil Science Study Program, Faculty of Agriculture, Sebelas Maret University held an event called Inbound Scholar Exchange on the Soil Biology and Health on Friday, October 29, 2021. The event took place at 09.00-11.00 WIB through the Google meet application. On this occasion, the Soil Science Study Program had the opportunity to invite Prof. Gamini Seneviratne who is a Senior Research Professor, National Institute of Fundamental Studies, Kandy, Sri Lanka as a resource person. The topic discussed at this event was “Next-generation Biofilm microbial ameliorators”. A series of Inbound Scholar Exchange events were hosted by a moderator, Prof. Dr. Ir. Sudadi, MP. The event began with remarks by the Dean of the Faculty of Agriculture, Prof. Dr. Samanhudi SP, M.Sc., IPM, ASEAN Eng. The event continued with the delivery of material, question and answer session, and closing.

On this occasion, Prof. Gamini Seneviratne shares some of his research results, one of which is entitled NBMs like biofilm biofertilizer (BFBF) enhances composition & capacity of antioxidants in rice grains. In his research, he used rice as his sample while CF (425 kg/ha NPK) and BFBF as his treatments. The study showed that 50% CF together with BFBF could increase Total Phenolic Content, Total Flavonoid Content, and Total Antioxidant Capacity which gave values ​​of 67%, 45%, and 80%, respectively. In conclusion, the use of 50% CF with BFBF can increase the composition and antioxidant capacity of rice grains. He also explained that antioxidants can counteract free radicals so that rice is safe and healthy for consumption. Some of the studies submitted included the title Characterization of extracellular polymeric substances of cyanobacterial, fungal, and bacterial biofilm complexes by liquid chromatography-mass spectrometry and Fourier transform infrared spectroscopy; Stabilization of sequestered soil Carbon using NBMs; Biofilm ameliorators can bring a paradigm change to agriculture and the environment; and Biofertilizer action: is it coming from microbial cells or exuded biochemicals?

After the presentation of the material is finished, the question and answer session begins. Participants in the question and answer session had high enthusiasm. There were several questioners who had the opportunity to ask questions directly or through the chat box regarding the material that had been delivered. All participants were satisfied with today’s event. Furthermore, thanks were conveyed by the organizers and participants for the knowledge that had been conveyed by the resource persons. The last event was the closing which was closed by the moderator.
