Isolation of Endophytic Bacteria from Green Gram and Study on Their Plant Growth Promoting Activities
A total of twenty five endophytic bacteria were isolated from green gram Vigna radiata (L.) plant. Four isolates which have shown better response for plant growth promoting effects on green gram plants were used as Plant Growth Promoting Bacteria (PGPB) in this study. It has been detected that up to 40% of the genomic 16S rRNA of isolated bacteria belongs to the Azotobacter genus. The result fo...
متن کاملMethods for distinguishing gram-positive from gram-negative bacteria.
Lysis by KOH and hydrolysis of L-alanine-4-nitroanilide were compared with the Gram reaction of aerobic, microaerophilic, and anaerobic bacteria. Both tests correlated well with the Gram reaction with nonfermentative bacilli and Bacillus species, whereas they did not correlate with nonsporulating anaerobes. Only campylobacteria were KOH positive and L-alanine-4-nitroanilide and gram negative.
متن کاملInner Plant Values: Diversity, Colonization and Benefits from Endophytic Bacteria
One of the most exciting scientific advances in recent decades has been the realization that the diverse and immensely active microbial communities are not only 'passengers' with plants, but instead play an important role in plant growth, development and resistance to biotic and abiotic stresses. A picture is emerging where plant roots act as 'gatekeepers' to screen soil bacteria from the rhizo...
متن کاملBacteriocins of gram-positive bacteria.
In recent years, a group of antibacterial proteins produced by gram-positive bacteria have attracted great interest in their potential use as food preservatives and as antibacterial agents to combat certain infections due to gram-positive pathogenic bacteria. They are ribosomally synthesized peptides of 30 to less than 60 amino acids, with a narrow to wide antibacterial spectrum against gram-po...
متن کاملHyaluronidases of Gram-positive bacteria.
Bacterial hyaluronidases, enzymes capable of breaking down hyaluronate, are produced by a number of pathogenic Gram-positive bacteria that initiate infections at the skin or mucosal surfaces. Since reports of the hyaluronidases first appeared, there have been numerous suggestions as to the role of the enzyme in the disease process. Unlike some of the other more well studied virulence factors, m...
