The rapidly growing water fern Azolla, which contains a nitrogen-fixing blue-green algal symbiont, has been studied as a possible system for photoproduction of molecular hydrogen. When this plant is grown on a combined nitrogen supply, photochemically generated hydrogen can be diverted through the algal nitrogenase system, which serves as a source of molecular hydrogen generated from water. Thi...

As a staple in Indonesian diet, rice demand increase along with the population growth. Therefore, order to fulfill continuous increase, researches were conducted land productivity. The of growth and productivity upland application Azospirillum sp. Azotobacter compost, Azolla, bran carrier studied. Nitrogen fixer applied as biofertiliser mean supply available nitrogen for This research was Cipar...

A pot experiment was conducted on Satla soil series in Terokhada Upazilla, Khulna during the boro season (February to June) see whether Azolla (biofertilizer) could be grown together with BRRI dhan 28 and compare effect of recommended dose N (100 kg ha-1) that different combinations urea (all treatments having doses P, K, S Zn). The laid out a completely randomized design 5 4 replications. pinn...

Purpose: To assess the potential of Azolla filiculoides, total body collected from a rice farm in northern Iran as source for biodiesel production. Methods: Solvent extraction using Soxhlet apparatus with chloroform-methanol (2:1 v/v) solvent blend was used to obtain crude oil from freeze-dried the Azolla plant. Acid-catalyzed transesterification was used to convert fatty acids (FA), monoglycer...

Azolla mycrophylla, Cherry leaves and tea waste are organic materials that have potential as liquid fertilizers because they able to bind nitrogen from the air contain high potassium. In manufacture of fertilizers, bioactivators such bamboo shoots needed accelerate fermentation process. The purpose this study was determine content N, P, K elements sensory tests on fertilizer (POC) combining myc...

background and purpose: the 2-chlorophenol (2-cp) and 4-chlorophenol (4-cp) are phenolic compounds which may have adverse effects on human and environment. therefore, removing these compounds from water and wastewater is necessary. this study aims to analyze 2-cp and 4-cp removal by using azolla filiculoides biomass. materials & methods: azolla biomass was sun dried, crushed and sieved to parti...

Azolla is an aquatic plant that has the potential to be used as animal feed due its high nutritive value and very productive plant. Thus, objectives of this study are determine compare nutrient mineral composition pinnata microphylla. A. microphylla plants have a introduced new alternative supplement ruminants. Samples were collected at Ladang Lembah Kaprima Hulu Seladang, Tenox Agribusiness (M...

Nitrogenase activity was measured in leaves along the main stem axes of Azolla pinnata R. Br. The activity was negligible in leaves of the apical region, rapidly increased to a maximum as leaves matured, and declined in aging leaves. In situ absorption and fluorescence emission spectra were obtained for individual vegetative cells and heterocysts in filaments of the A. pinnata and Azolla caroli...

Attempts to increase food crop yields by intensifying agricultural systems using high inputs of nonrenewable resources and chemicals frequently lead to de-gradation of natural resources, whereas most technological innovations are not accessible for smallholders that represent the majority of farmers world wide. Alternatively, cocultures consisting of assemblages of plant and animal species can ...
