Their presence decreases the stress levels and significantly eliminate common air pollutants. In a limited space, the home garden is an integrated system that produces a variety of foods and agricultural products, including staple crops, vegetables, fruits, medicinal plants and more. The importance of the backyard garden as a source of biological diversity is recognized in this context. When it comes to home gardens, whether in rural or urban regions, the structure and multi-functionality allow for the supply of multiple advantages for both ecosystems and humans. Home gardens conserve a significant amount of genetic variation in plants, both between and within species. Gardening at home is a significant part of social and cultural life, as well as a way for families to earn more money and improve their lives. This review has described the importance of plants in the home and role of home garden prevailing in Saudi Arabia. Biocultural and biological relevance of home gardens are addressed, along with future research challenges and opportunities that could help define and promote the role of house gardens in agricultural biodiversity conservation and cultural legacy preservation.","PeriodicalId":9156,"journal":{"name":"Bioscience Biotechnology Research Communications","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44314796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although toluene and phenol have various beneficial applications, many studies reported the massive negative impacts of these contaminants on the environment and on human health. This study aims to provide an assessment of biodegradation potential of Staphylococcus pasteuri isolated from the industrial area at the coast of Red Sea, Jeddah, Saudi Arabia. From 29 isolates, a strain, that exhibits a notable growth on mineral salt medium supplemented with phenol and toluene as a sole carbon source, was chosen for further investigation. Different optimization conditions have been examined for optimal degradation; two concentrations of phenol and toluene (0.5% & 1.0%) and different incubation temperatures. Growth assessments was measured by optical density (OD) of phenol and toluene using spectrophotometer. Maximum OD for phenol and toluene: (ODmax= 0.787) and (ODmax= 0.969) compared to the abiotic control of (ODmax= 0.152) and (ODmax= 0.182) respectively. Degradation of phenol and toluene was also measured using high performance liquid chromatography (HPLC). In addition, molecular identification of the isolates was carried out using 16S rRNA analysis highlighted the isolated strain is Staphylococcus pasteuri (strain ATCC 51129) with the accession number (NR114435).

The aim of this study was to prepare nano-emulsions using Coriander and Dill and Flaxseed essential oils and investigate their antibacterial activities. Three nano-emulsions (NEs) were produced by mixing essential oils, surfactants and water with droplet sizes of NEs formulations in the range of 25-62 nm. No toxicity was recorded for Coriander and Dill at 100 μl/ml while Flaxseed NE showed moderate toxicity. Standard local pure cultures of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae and Candida albicans were obtained. Dill NEs and Coriander NEs showed moderate activities against both S. aureus and E. coli with inhibition zone diameter rang ing from 12-14 mm and weak activities against K, pneumoniae and P. aeruginosa. The three tested Oil Nanoemulsions showed weak inhibition activity with an inhibition zone diameter of 10 mm against Candida albicans as a test yeast. The best minimum inhibitory concentrations (MICs) of nanoemulsions was for flaxseed NE against all the tested Gram negative bacteria but the results were higher than that obtained by the control antibiotic that showed excellent activity. In conclusion, the tested NEs showed inhibitory activity against the tested bacteria due to inhibition of vital microbial functions such as cellular transport and/or energy production.","PeriodicalId":9156,"journal":{"name":"Bioscience Biotechnology Research Communications","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44983732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the lichens tested, Dirinaria applanata exhibited strong antioxidant activities than Parmotrema andium. The methanol and acetone extracts of D. applanata showed DPPH radical scavenging activities (IC50 value) as 471.16±0.85μg/ml and 519.79±1.29μg/ml whereas in P. andium IC50 value was 534.77±0.75μg/ml and 600.77±0.95μg/ml respectively. Similar result was also observed in H2O2 scavenging assay and FRAP. An interesting strong relationship between total phenolic and flavonoid contents and their antioxidant activities in both the Lichen species was marked as determined with respect to gallic acid and quercetin equivalents.

One of the most effective ways to tackle the threat is to use biofertilizer. Plant growth promoting bacteria (PGPB) are an important bacterial source for microbial fertilizers that can boost agricultural yields by encouraging plant growth. Bacterial isolates isolated from Saurashtra region, Gujarat, India were analysed for their capability to solubilize inorganic 'P' from tri calcium phosphate and production of indole acetic acid (IAA) quantitatively by bacterial. Production of ammonia, siderophore and hydrogen cyanide (HCN) by selected bacteria isolates was analysed. Biochemical characterization of selected bacterial isolates was done using Vitek 2 Compact system. Isolate GFS15C2 showed highest amount of phosphate solubilization, followed by isolate GFS07C1 and GFS01C1. Bacterial isolate GFS15C2 produced highest amount of IAA. All bacterial isolates were able produce ammonia. Eight bacteria isolates were be to produce HCN. Siderophore was produced by 14 bacterial isolates. In biochemical characterization all the bacterial isolates were able to use D-glucose. Based on biochemical characters clustering of bacteria isolates was done using Paleontological statistics software package for education and data analysis(PAST). Using cluster analysis by euclidean distance method based on biochemical characterization isolates GFS16C2 & SCS12C3 was found to have distinct characters than other isolates. The present study attempts to characterize PGPB which could be harnessed to improve plant growth. Several phosphate solubilizers and IAA producers also showed production of siderophores and HCN which suggests that these organisms do possess biocontrol ability. These PGPB microbial inoculants can be utilized to improve agricultural systems or as an alternate means of environmentally friendly plant disease biocontrol.","PeriodicalId":9156,"journal":{"name":"Bioscience Biotechnology Research Communications","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45651510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite a good literature, there are different claims about the use of color channels as red, green and blue for extraction of PPG signal, i.e., pulse rate from the videos captured through high resolution cameras. In this article, we present the technique for extracting the heart beat rate (pulse rate) from the videos captured through the mobile cameras for all three color channels and thier analysis. Experiments were performed on a DMIMS database comprising 720 videos, out of which we used 25 videos for the analysis. The pulse rate estimated from the blue channel, was in good agreement with reference data extracted using an MP20 monitor, used as the gold standard. The findings of the present study demonstrated the non-invasive color intensity method for detection of pulse rate from the pre-recorded video of 30 seconds. The algorithm is tested on the DMIMS dataset which we have captured in uncontrolled setting. The green channel is proven to be statistically significant for the video recorded followed by red and then blue channel. The accuracy of the pulse extracted is still low because of low signal to noise ratio.We therefore conclude that the presented technique is best for pulse rate extraction through a blue channel followed by red and green channels respectively.","PeriodicalId":9156,"journal":{"name":"Bioscience Biotechnology Research Communications","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47224600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to analyse the efficacy of Cucumis melo L. on chromium VI (K2 Cr2 O7)-induced rats. For 42 days, male albino rats (160–20 g) were given the stated oral LD50 dosage of chromium VI (K2Cr2O7) (10 mg/kg body weight). After 42 days, chromium-induced rats were administered with two different concentrations of Cucumis melo L. and ascorbic acid (250 mg/kg, 500 mg/kg body weight) for 7 days. Following therapy, blood was drawn and analysed for a variety of biochemical markers.The results revealed that ingestion of either plant extract, ascorbic acid, or their combination on chromium 6 induced rats significantly increase the activity of Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST) and decreased the activity of Gamma Glutamyl transferase (γ-GT) was recorded. This study has proven that fruit extract particularly its combination with ascorbic acid has a potential prophylactic effect. Cucumis melois vital for modifying the Chromium (VI) induced toxicity on male albino rats. Indeed, the recommended fruits should be consumed to the Chromium (VI) deposited harmful region since they may protect cells from environmental stress.","PeriodicalId":9156,"journal":{"name":"Bioscience Biotechnology Research Communications","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48893925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
