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...

Denitrifying capability of glycogen accumulating organisms (GAOs) has received great attention in environmental science and microbial ecology. Combining this ability with granule processes would be an interesting attempt. Here, a laboratory-scale sequencing batch reactor (SBR) was operated to enrich GAOs and enable sludge granulation. The results showed that the GAO granules were cultivated suc...

Ensiling is a simple and effective method of alleviating shortage forage for ruminants. This study aimed to investigate the effects lactic acid bacteria (LAB) inoculants stage-increased temperature on fermentation characteristics chemical composition oat silage Qinghai–Tibet Plateau. The was treated with local laboratory inoculant (I) commercial (S) stored at ambient (<10 °C) or (5, 10 15 da...

A promising solution for phytoremediation of metal-contaminated soils is to use plants in combination with phosphate-solubilizing bacteria (PSB). In this study, we subjected isolate PSB from paddy soil and investigate their ability improving the lead (Pb2+) by a weed plant (Echinochloa colona (L.) Link) as well promoting growth E. under Pb stress condition. Total 06 (labeled TB01 TB06) were iso...

Nontoxic polymers PVP and Na-alginate may provide a favorable environment for the survival of bacteria. Therefore, were added to growth medium develop liquid inoculant Bradyrhizobium japonicum strain. The strain was identified by 16S rDNA sequencing. addition (1.8%) (0.2%) in promoted better (1.93 × 109 cells mL−1) B. compared control (3.50 102 after 6 months storage. combination ensured 1.53 1...

Effects of harvesting ruminal micro-organisms from ruminal ̄uid on patterns of gas production were investigated in experiment 1 by incubating 200 mg DM of pure cellulose, oatfeed, ryegrass, cocksfoot, wet and dry season kikuyu grasses with either diluted ruminal ̄uid or harvested ruminal bacteria. Gas production degradability parameters obtained from ®tting the data to the model Gas ˆ B(1ÿ expÿ...

Bradyrhizobium elkanii is successfully used in the formulation of commercial inoculants and, together with B. japonicum, it fully supplies the plant nitrogen demands. Despite the similarity between B. japonicum and B. elkanii species, several works demonstrated genetic and physiological differences between them. In this work Representational Difference Analysis (RDA) was used for genomic compar...

Microbial amendments have received considerable interest in sustainable agriculture for enhancing crop productivity, improving soil quality, and reducing inputs of chemical fertilizers and pesticides (Hussain et al., 1999). Microbial amendments are also known as biofertilizers, biodynamic fertilizers or microbial inoculants, which are comprised of living microorganisms that can function as chem...
