Photocatalytic degradation proficiency was studied for bromothymol blue dye. Phytochemicals-coated Nickel Oxide nanoparticles demonstrated antibacterial properties against bacteria (gram negative strain of E. coli, Pseudomonas spp. and gram positive strain of Bacillus spp.) by showing highest zone of inhibition (19 mm, 22 mm, 15 mm).the antioxidant activity of the synthesized nanoparticles were also examined and the result show that the fabricated nanoparticles exhibited significant radical scavenging activity.

In this study, the synthesis of dimeric disulfide-Schiff bases was carried out using two methods. The structures of the obtained Schiff bases were elucidated by various spectroscopic methods as well as elemental analysis. The Schiff base derivative compounds (3a-6) were screened for in vitro antibacterial activity against multidrug-resistant microorganisms using microdilution method. All the tested compounds showed varying inhibition zones against the pathogens.

The sensitivity of some pathogenic bacteria used as test organisms to the new compounds 1–3 was determined. 1 showed appreciable antimicrobial activity with the diameter of inhibition zones ranging from 11 to 18 mm. 1 was active against the two multidrug resistant bacteria Acinetobacter baumannii and Staphylococcus aureus. Minimal inhibitory concentrations (MICs) of compound 1 were recorded for all the tested bacteria using the fluorescein diacetate method and the recorded MIC values ranged from 4 to 6 µM.

This strain showed high activity in fresh goat cheese (11–15 mm inhibition zone) having the ability to prevent the development of S. aureus, also reducing the inoculum level of pathogen by about 1 log cycle. These results revealed that this strain could be a promising biopreservative starter for the dairy industry. To the author ’s knowledge, this is the first report of L. plantarum being isolated in salted dried camel meat.

Among all the species of Andrographis, Andrographis echioides is given importance recently for its excellent medicinal properties. The study of Andrographis echioides as anti-microbial agent was found necessary for gaining insight into this medicinal flora and its real value. The ethyl acetate extract of leaves recorded highest anti-fungal activity against all the selected pathogens viz., Pythium aphanidermatum, Phytophthora capsici, Macrophomina phaseolina...

The efficacy of six different systemic fungicides and two combi-products were evaluated for inhibition of growth of pathogen at three different concentrations. Among systemic and combi-products fungicides were evaluated, the cent per cent inhibition was observed in Propiconazole 25 % EC, Tebuconazole 250 EC, Azoxystrobin 18.2 % + Difenconazole 11.4 % SC and Tebuconazole 50 % + Trifloxystrobin 25 % WG at all the concentrations.

Phytochemical and antimicrobial screening analysis of Mangifera indica and Carica papaya indicated the presence of alkaloid, saponin, flavonoid, steroid, tannin, phenol and glycoside. Extract of Mangifera indica and Carica papaya were investigated for their antimicrobial activities. The ethanolic extract produced zone of inhibition higher in diameter than aqueous extract against Escherichia coli, Pseudomonas spp, Staphylococcus spp, Streptococcus spp and salmonella spp.

Five antibiotics viz. Streptomycin sulphate, Streptocyclin, Chloramphenicol, Ampicillin and Rifamycin and One fungicide viz. Copper-Oxychloride were tested against Xanthomonas axonopodis pv Citri. in vitro. The antibiotic sensitivity against sixteen isolates was studied by paper disk method. Streptomycine sulphate (500ppm) was significantly superior over other treatments with maximum inhibition zone in all Sixteen isolates of Xanthomonas axonopodis pv citri.

The continuous presence of the pathogen in the orchard throughout the season has led to many fold speculations on possible survival of the pathogen on some alternate hosts grown in and around the garden. Severity of incidence and losses varies among different isolates and influenced by existing climatic conditions and geographical distribution (Mondal and Sharma, 2009; Mondal and Singh, 2009; Petersen et al., 2007; Mondal et al., 2012).

In present study Vitex negundo leave’s extract was used to assess the antibacterial activity on cotton fabric. Extraction of phytochemicals was carried out using different solvents like ethanol and aqueous. Total phenolic content (TPC) results revealed that TPC of Vitex negundo leave’s extract were highest in case of ethanolic extraction as compared to aqueous. It was observed that mild to moderate antibacterial properties were present in ethanolic extract as compared to aqueous extract. Clear zone of inhibition was observed on cotton fabric against E coli and S. aureus.

In the present study, 8 Actinomycetes were isolates from rhizospheric soil from Karanja (Lad) District wahism. Out of 8 Actinomycetes isolates, two isolates was found to be sensitive against all isolates and shows very excellent zone of inhibition. Antagonastic activity against human pathogens like, S. aureus, E. coli, P. aeruginosa and P. vulgaris, was also carried out. From the complete observation it was noticed that isolate N obtained from neem soil and H from Hibiscus soil is having excellent antagonistic activity in controlling all the test pathogens.

In in vitro evaluation of cultural extract of Chaetomium globosum against Fusarium, Sclerotium and Rhizoctonia, it was observed that inhibition of pathogen was increased with increase in concentration of metabolite indicating the antifungal properties against pathogen. Chaetomium globosum showed maximum antagonistic effect to Fusarium (51.50%) at 100% concentration. Significantly minimum inhibition zone (20%) was observed at 25% for Fusarium spp. Effect of culture filtrate did not show any inhibition effect against soil borne pathogens Sclerotium and Rhizoctonia.

The present investigation was undertaken for in vitro screening of antibacterial activities of different extracts (ethyl acetate, methanol and benzene) of various plant parts of Achyranthes aspera, Azolla pinnata, Cissus quadrangularis. In vitro antibacterial efficacy of plants selected was assessed by well diffusion method against pathogenic bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. The ethyl acetate extract of Cissus quadrangularis exhibited highest zone of inhibition against S. aureus (25±1.3mm) followed by Achyranthes aspera (20.0±0.

A total number of 10 rhizosperic bacteria were isolated from root environment of some healthy plants of a drastic diseased field with massive blighted symptoms of Trichosanthes dioica of Akilpur of Hooghly district, West Bengal (22.94º E 88.12º N) where soil is alluvial in nature. Among the isolates, one strain TR9 showed remarkable plant growth promoting activity. Cell free culture filtrate of TR9 produced clear zones of inhibition (diameter ranging from 1.67cm to 2.67cm) against different plant pathogenic fungi viz.

The use of plant products as medicine has emerged from traditional days to modern times of medicine in order to improve the quality life of the patients worldwide. Nature-derived medicines are considered safer with less or no side effects. The antibacterial effect of the leaves of Annona muricata was evaluated on bacterial strains of ESBLs: Escherichia coli and Klebsiella pneumoniae are tested which were isolated from D.Y. Patil Hospital, Nerul, NaviMumbai.
