“…A callus suspension culture is generated by growing callus in plant growth medium for approximately 20 days, during which they begin to release secondary metabolites. Comparison of the antibacterial activity of callus extracts and plant extracts from Alternanthera maritime revealed very similar inhibition patterns in the growth of several Gram‐negative and Gram‐positive bacteria (Salvador et al ., ). Similar antimicrobial activity was observed in the case of leaf and callus extracts of Rauvolfia tetraphylla and Physalis minima (Shariff et al ., ).…”

A multitude of natural products from plant extracts have been tested for their ability to inhibit the progression of several diseases including cancer. A novel approach of evaluating plant (rice) callus suspension cultures for anticancer activity is reported. The ability of different dilutions of rice callus suspension cultures to inhibit growth of two human cancer cell lines was tested employing varying cell numbers and different incubation times. A crystal violet assay was performed to assess cell viability of the cancer cell lines. Furthermore, microscopic analysis was carried out to determine the effect of the rice callus culture on the morphology of the cancer cells. Rice callus suspension cultures significantly inhibited the growth of human cancer and renal cell lines at densities of 5000 and 10000 cells/mL when incubated for 72 and 96 h. Rice callus suspension culture was more efficient than paclitaxel (Taxol®) and etoposide in selectively killing human colon and renal cancer cell lines compared with a control cell line (human lung fibroblasts). The use of plant callus suspension cultures is a novel approach for inhibiting the growth of cancer cells, which will lead to the development of new agents for selectively killing cancer cells.

Present study investigates antimicrobial, antioxidant activity and phytochemical profiling of alcoholic extracts of whole fruit of Actinidia deliciosa (kiwi fruit). Cold and hot extracts of whole Actinidia deliciosa fruit prepared in methanol and ethanol and their different concentrations were tested against common nosocomial infections and human pathogens of skin, gestrointestinal tract and upper respiratory tract. Extracts were evaluated for their phytochemical constituents and antioxidant activity. Cold ethanolic extract of whole kiwi fruit has good antimicrobial activity as it inhibited the growth of almost all test organisms at concentration less than 20 mg/ml. Cold ethanolic extract was also found to be effective against Candida albicans at a concentration of 38.33 mg/ml. Antioxidant activity was examined by DPPH radical scavenging assay, highest antioxidant activity was displayed by cold methanolic extract. The qualitative phytochemical analysis of the extracts revealed the presence of alkaloids, flavonoids, saponins, cardiac glycosides, tannins and terpenoids in whole fruit of Actinidia deliciosa.

“…To find a solution there is a need to find alternatives to these chemical antibiotics. However, establishment of robust and suitable methods to provide continuous and effective alternatives against microbes might be provided by tissue culture techniques, which are independent on external environmental conditions [11][12][13][14] . Ochradenus baccatus Delile is a member of Reseadasea family 15 and widely spread in Middle Eastern deserts from Pakistan to the north of Africa 16 .…”

Ochradenus baccatus Delile is a wild medicinal plant that produces several natural compounds with medicinal benefits. In this study, microshoots of Ochradenus baccatus were exposed to osmotic stress conditions consisting of Murashige and Skoog solid media (MS) media that containing different osmotic agents (sugar types) at a range of concentrations (including 0.1, 0.2, 0.3 or 0.4 M). The purpose was to test their effects on microshoots’ growth and antimicrobial activities against selected strains of bacteria and one strain of fungi. It has been found that growth parameters (including shoot length and proliferation) of Ochradenus baccatus microshoots declined with increasing sugar concentration in the media, but at the highest concentrations of 0.4M mannitol, the micorshoots could not survive. Generally, aqueous extracts of the stressed microshoots were more effective against the tested microbial strains than the methanolic extracts in most experiments. Staphylococcus aureus was found to be the most affected microbe to both extract types. Also, exposing the microshoots to osmotic stress had improved antimicrobial powers in both extracts types. Aqueous extract of microshoots that pre-grew in media with (0.4 M sucrose) was interestingly found to inhibit growth of Staphylococcus aureus and Candida albicans with minimal inhibitory concentration (MIC) values of (0.195, 0.78 mg/ml). These values were similar to those obtained from the antibiotic treatments. Other biotechnological techniques like genetic transformation are suggested to be also used for production of elite strains of Ochradenus baccatus with super antimicrobial potential.
