Microbial intervention in agriculture: An overview
With increase in population, rapid urbanization and industrialization, land area under agricultural production is decreasing day by day. In order to feed the huge population, more production is required from lesser area, which triggers continuous applications of higher doses of inorganic fertilizers in an injudicious manner posing serious harm on soil health, further rendering large fraction of land unfit for...

Endophytic mycobiota from leaves of Indigofera suffruticosa Miller (Fabaceae): The relationship between seasonal change in Atlantic Coastal Forest and tropical dry forest (Caatinga), Brazil
Endophytic fungi were isolated from leaves of the medicinal plant, Indigofera suffruticosa collected at the Atlantic Coastal Forest and tropical dry forest (Caatinga), Pernambuco, Brazil, during the dry and rainy seasons. A total of 107 fungal isolates, representing nine fungal taxa, were obtained and classified as Ascomycota, among them Colletotrichum gloeosporioides with relative frequency (fr) 27.1% and...

Cleopatra mandarin (Citrus reshni Hort. Ex Tan.) modulate physiological mechanisms to tolerate drought stress due to arbuscular mycorrhizal fungi and mycorrhizal helper bacteria
The influence of Glomus intraradices colonisation on growth and reactive oxygen metabolism of Cleopatra mandarin (Citrus reshni Hort. Ex Tan.) seedlings treated with mycorrhizal helper bacteria, that is, phosphate solubilising bacteria containing a mixture of Bacilus subtilis and B. megaterium, Azospirillum braisilence or Providencia sp.) in potted culture was studied under well-watered or drought stress conditions....

AmpC and metallo beta-lactamases producing Gram negative bacteria in patients with hematological malignancy
Resistance to broad spectrum β-lactams mediated by AmpC and metallo beta-lactamases (MBLs) enzymes is a rising problem worldwide. The wide dissemination of Gram negative bacteria harboring these enzymes represents a significant clinical threat during the last decade, which is mainly due to treatment failure and restriction of therapeutic options. This problem should be really estimated in our locality with special...

Antibacterial activity of two extracts from Rubus fruticosus L. against resistant pathogens and their antioxidant potential
One of the most serious threats to public health across the world is the spread of antibiotics resistant pathogens. This situation obliges researchers from all over the world to focus on how they can overcome this obstacle mainly by searching or synthesizing new molecules to neutralize microbes and to overcome the phenomenon of resistance. One of the main reservoirs of potentially active molecules is the plantae...

Evaluation of plant products and antagonistic microbes against grey blight (Pestalotiopsis theae), a devastating pathogen of tea
The present study was carried out to evaluate the effect of different oils (lemongrass, neem, karanj, zinger, eucalyptus and patchouli oils), different plant product extracts (garlic, zinger, false ashoka and datura) and different antagonistic microorganisms (different species of Trichoderma spp., Bacillus sp. and Pseudomonas sp.) on grey blight of tea, Pestalotiopsis theae. Results reveal that eucalyptus oil and neem...

Effect of the addition of water-soluble soybean extract and probiotic culture on chemical characteristics and folate concentration in yogurts produced with goat’s milk
Four yogurts from goat’s milk were elaborated and water-soluble soybean extract (WSSE) in the supplementation of 14.8 g/L and Bifidobacterium lactis probiotic culture at 2% were added during processing. Chemical aspects and folate concentration were evaluated during the preparation for 29 days at 4°C. Regarding protein and fat analysis, treatments with added WSSE presented higher values; the yogurt with added...

Microbiologic quality of hand creams in Pelotas, Brazil
The use of cosmetics has been widely accepted; among them, hand creams are commonly used with the principal function of hydration. However, for the user’s safety, and to ensure good-quality products, these products should follow the Good Manufacturing Practices (GMP) and a strict microbiological quality control. In this study, six samples of hand creams, two industrialized and four compounding were evaluated by...

Meloidogyne incognita and Fusarium oxysporum interaction in Gerbera
Pot culture experiments were carried out to study the interactive effect of root knot nematode, Meloidogyne incognita and the fungus, Fusarium oxysporum in Gerbera, Gerbera jamesonii Hook. Sequential and concomitant inoculation of the nematode and fungus was done to observe the disease severity in the plants due to the individual effect and interactive effect of nematode and fungus. It was observed from the study that...
