The use of Azolla filiculoides (AF) for the removal of Acid Red 88 dye (AR88) from aqueous solutions at different contact times, temperatures, pH, adsorbent doses and initial dye concentration was investigated. The extent of dye removal decreased with increasing adsorbent dosage and AR88 concentration, also increased with increasing contact time and temperature. The adsorption isotherms are des...

Arthrobacter species, isolated from the leaf cavities and the microsporocarps of the aquatic fern species Azolla pinnata and Azolla filiculoides, produced indole-3-acetic acid (IAA) in culture when the precursor tryptophan was added to the medium. No IAA production was detected in the absence of tryptophan. Maximum IAA formation was obtained in the first 2 d of incubation. Part of the tryptopha...

Programmed cell death (PCD) is a genetically-based cell death mechanism with vital roles in eukaryotes. Although there is limited consensus on similar death mode programs in prokaryotes, emerging evidence suggest that PCD events are operative. Here we present cell death events in a cyanobacterium living endophytically in the fern Azolla microphylla, suggestive of PCD. This symbiosis is characte...

Tilapia (Oreochromis niloticus) is one of the prospective freshwater fish producers to be developed in Indonesia. fishcommodities that has received great attention from fisheries because itis easy breed, grows fast, and tolerant unfavorable environments. One ofthe problems tilapia farmersis high feed cost. The factor affects growth nutritional content feed. To increase thegrowthoftilapia,qualit...

Biochemical and nutritional studies were carried out to evaluate the potential of Azolla (Azolla pinnata R. Brown) meal, AZM, as a feed resource in the diet of egg-type chicks. In a completely randomized design, 30 two weeks old Nera brown chicks were assigned to each of the four dietary treatments containing 0, 5, 10 and 15% azolla meal. Chemical analysis indicated that azolla meal contained (...

Experiments were conducted to determine the influence of Chlamydomonas sp. on nitrogen fixation (C(2)H(2) --> C(2)H(4)) in Azolla filiculoides and on the nitrogen fixation and growth of free-living Anabaena azollae 2B organisms. Inoculation of azolla medium with Chlamydomonas sp. was associated with decreased nitrogenase activity in A. filiculoides and with increases in the density of a fungal ...

OBJECTIVE The experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers. METHODS In experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; D1 (control), D2 (D1 with 1 mL multivitamin/liter water), D3 (D1 with 1 mL acidifier/...

A total of 9 plant extracts were tested, using two different kinds of extracting methods to evaluate the antioxidant and antimicrobial activities from Pilea microphylla (Urticaceae family) and including toxicity test. Antioxidant activity were tested by using DPPH free radical scavenging, also total phenolic contents and total flavonoid contents were determined. Toxicity assay carried out by us...
