Aloe Barbadensis

Synthetic antimicrobial agents, like triclosan, used in many cosmetics are now associated with serious health problems, beginning with skin irritation to cancer. This calls for alternative antimicrobial agents. Many plant extracts have the potential to inhibit the growth of microorganisms and perhaps kill them and thus can serve as alternative antimicrobial agents in cosmetic formulations. To demonstrate this, a hand-washing liquid soap was prepared in the presence of varying concentrations of aloe vera extract and tested in-vitro against common skin microbes. First, a liquid soap paste was prepared by saponifying a vegetable oil blend containing olive oil (80.0 %w/w), coconut oil (14.3 %w/w) and castor oil (5.7 %w/w) with aqueous KOH solution (22.5 %w/w) at a relatively high temperature (200 °C). Second, the soap paste was diluted with distilled water in the presence of varying concentrations (0 to 66.67 %w/w) of aloe vera extract to obtain hand-washing liquid soap samples, with the extract acting as an antimicrobial agent. Third, the liquid soap solutions were characterised in terms of foaming, wetting and cleansing abilities and the ability to inhibit the growth of Staphylococcus aureus, Pseudomonas aeruginosa and the fungus Aspergillus flavus. These were compared with those of a commercial (Astonish) hand-washing liquid soap sample containing triclosan (0.1 %w/w) as an antimicrobial agent. The liquid soap solutions exhibited excellent foaming, wetting and cleansing abilities, similar to the commercial liquid soap solution. In addition, the liquid soap solutions gave an average zone of inhibition between 9.0±0.3 mm and 11.0±0.2 mm for S. aureus, 7.0±0.1 mm and 10.0±0.2 mmfor P. aeruginosa and also inhibited the growth of the fungus A. flavus. These results compare favourably ( p= 0.05)with the commercial liquid soap solution, which gave an average inhibition zone of 9.00±1 mmfor both bacteria and also inhibited the growth of the fungus. This indicates that aloe vera extract can be used as an antimicrobial agent in the formulation of antimicrobial hand-washing liquid soap and other related products, rather than synthetic agents which are inherently harmful.

Insight Into

Growing demand for safe foods coupled with the intent to reduce food waste, seeing as much of it is lost through contamination by spoilage microorganisms, leads to research on antimicrobial agents such as LAE (Nα-lauroyl-L-arginine ethyl ester monohydrochloride). This compound has great antimicrobial potential against a range of microorganisms and, therefore, its use may be of extreme importance for the food industry in the search for antimicrobial agents with a broad spectrum of action. Thus, the objective of this article is to review the research involving LAE, when studied in vitro, in vivo and in the incorporation in different packaging in order to be released in a controlled manner for food products. In conclusion, despite the fact that it has a strong antimicrobial activity, it is still little known and is not accepted in all countries, including Brazil. With greater insight into this antimicrobial agent, more countries could use it, supporting worldwide in food preservation.

Antibiotic resistance is an eminent threat for the survival of mankind. Nosocomial infections caused by multidrug resistant microorganisms are a reason for morbidity and mortality worldwide. Plant-based antimicrobial agents are based on synergistic mechanisms which prevent resistance and have been used for centuries against ailments. We suggest the use of cost-effective, eco-friendly Aloe Vera Barbadensis Miller (AV)-iodine biomaterials as a new generation of antimicrobial agents. In a facile, one-pot synthesis, we encapsulated fresh AV gel with polyvinylpyrrolidone (PVP) as a stabilizing agent and incorporated iodine moieties in the form of iodine (I2) and sodium iodide (NaI) into the polymer matrix. Ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FT-IR), x-ray diffraction (XRD), microstructural analysis by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) verified the composition of AV-PVP-I2, AV-PVP-I2-NaI. AV, AV-PVP, AV-PVP-I2, AV-PVP-I2-NaI, and AV-PVP-NaI were tested in-vitro by disc diffusion assay and dip-coated on polyglycolic acid (PGA) sutures against ten microbial reference strains. All the tested pathogens were more susceptible towards AV-PVP-I2 due to the inclusion of “smart” triiodides with halogen bonding in vitro and on dip-coated sutures. The biocomplexes AV-PVP-I2, AV-PVP-I2-NaI showed remarkable antimicrobial properties. “Smart” biohybrids with triiodide inclusions have excellent antifungal and promising antimicrobial activities, with potential use against surgical site infections (SSI) and as disinfecting agents.

Household Cleaning Products

Household cleaning products are commonly used worldwide to enhance cleanliness and hygiene. Most household cleaning products marketed commercially today are very expensive, unaffordable and contain toxic and harmful chemicals. Some may even damage the cleaned surface through corrosion or abrasion. The aim of this study was to produce eco-friendly household cleaning products from locally available materials. The study was carried out in Omuku, Rivers State. The population was made up of all 182 housekeepers and working mothers across the five school of the Federal College (Technical) of Education and 15 hotels. The stratified random sampling technique was used to sample 102 working mothers and housekeepers. Household cleaning products such as liquid soap was produced from local materials such as orange, lemon, tangerine, coconut oil, and palm ash. Toilet cleaner was formulated from ginger and aloe vera extracts and activated carbon while floor wash was made from local gin, liquid wash, alcohol, lemon and sodium chloride. The products were subjected to sensory acceptability. A nine Point Hedonic Scale questionnaire was also constructed and administered to the respondents for data collection. Mean rating was used to analyze the research questions and sensory evaluation and Z-test was used to analyze the hypotheses at 0.05 level of significance. The result of the study revealed that the locally produced household cleaners were acceptable in terms of quality. The respondents’ response differed with respect to the colour and the odour of locally made household cleaners especially the locally produced liquid soap. The study also revealed that the locally produced household cleaners differed from commercial ones only in terms of colour. The result therefore indicates the potentials of utilizing locally available materials for the production of non-toxic, natural and environmentally safe household cleaning products.

ABSTRACT The susceptibilities of Helicobacter felis (15 strains), H. bizzozeronii (7 strains), and H. salomonis (3 strains) to 10 antimicrobial agents were investigated by determination of the MIC using the agar dilution method. No consistent differences were noticed between the different Helicobacter species, which were all highly susceptible to ampicillin, clarithromycin, tetracycline, tylosin, enrofloxacin, gentamicin, and neomycin, as demonstrated by low MICs. Higher MICs were obtained for lincomycin (up to 8 μg/ml) and spectinomycin (up to 4 μg/ml). Two H. felis strains showed a MIC of 16 μg/ml for metronidazole, suggesting acquired resistance to this antimicrobial agent.

Ethnomedicinally, the family Liliaceae is prominent in controlling skin, wound and fungal infections. A carboxylic fatty acid derivative has been isolated from Aloe vera leaves and its structure was elucidated on the basis of NMR and FT-IR analysis. The compound was formulated as ointment with the aid of polymer based delivery agent. The ointment and the uncontaminated fatty acid have been scrutinized aimed at their anti-infectious potential. Individually, the pure compound and the formulated ointment exhibited growth inhibitory activity against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Candida albicans and Talaromyces flavus. Minimum inhibitory concentration (MIC) values were found to be appreciably low, ranging between 0.30 and 2.50 mg/ml. The formulated ointment displayed highly significant inhibitory activities against all six pathogens compared to the unformulated compound. The MIC values of the ointment ranged between 0.08 and 1.25 mg/g. The in vitro antibiotic activity studies discovered that, both the pure compound and the formulated ointment showed potency against the selected multi-resistant microorganisms tested in the current work. These findings suggest that the isolated carboxylic acid derivative may be beneficial in the discovery of antibiotics highly potent against drug-resistant pathogens. Furthermore, it may add to the improvement of preservatives in the food industry. Lastly, it could be considered as new source of natural antibiotics in the pharmaceutical industry.
