What are biodigesters?
A biodigester system utilizes organic waste, particularly animal and human excreta, to produce fertilizer and biogas. A biodigester consists of an airtight, high-density polyethylene container within which excreta diluted in water flow continuously and are fermented by microorganisms present in the waste. The fermentation process is anaerobic, i.e., it takes place without oxygen, and the bacteria responsible for decomposition are methanogenic (i.e., they produce methane, also known as biogas).
Pre-germinated seeds or seedlings are directly planted in soil or broadcast in flooded field under this technology. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.
Rainfall can provide some of the cleanest naturally occurring water that is available. There is considerable scope for the collection of rainwater when it falls, before huge losses occur due to evaporation, transpiration, and runoff and drainage - before it becomes contaminated by natural means or man-made activities. Rainwater harvesting is a particularly suitable technology for areas where there is no surface water, or where groundwater is deep or inaccessible due to hard ground conditions, or where it is too salty or acidic.
Compositions and Methods for Improving Rice Growth Resistance to blast and Restricting Arsenic UptakeType:Product
This invention relates to the use of microbes isolated from a rhizosphere of rice to provide anti pathogenic effect on rice plants improve biomass and growth and restrict arsenic uptake by rice plants.
Rice is an essential food source for more than 50% of the world’s population. Heat and drought stress are important factors limiting rice production exacerbated by the impending threat of climate change. Stress tolerant cultivars are needed to expand rice production. Drought tolerant varieties have been developed but in narrow genetic backgrounds characterized only in simulated growing conditions.
The presence of lead kills most bacteria making it impossible to bioremediate soil contaminated with lead. This bacterium is able t o survive and bioconcentrate lead on or in its membrane which probably allows it to survive as well as to remove lead from contaminated soils The use of a bacteria for on-site remediation of soils by accessing the soil to a bioreactor with encapsulated bacterium that can be separated later to the soils or using a membrane to immobilize the bacterium. This is a soil organism which will survive in the soil at pHs of soils (around 4).
