The obtained results showed that, Gram-positive bacteria had more sensitive for phytic acid than Gram-negative bacteria. Bacillus anthrakoid and Staphylococcus aureus were more sensitive at concentrations of pure phytate 5, 6 %. Inhibition effects in Escherichia coli O157:H7 and Staphylococcus aureus were 20.33 and 38.67 mm, respectively at 6% of pure phytate. Moreover, a moderate inhibition against fungi was observed. Besides the pure phytic acid and phytate extracted from wheat bran have an inhibitory effect on many types of microorganisms. The antioxidant activity of pure phytate increased with increasing the concentration, where, the scavenging activity was 22, 23 and 36% at concentration 1, 3, and 5 mM, respectively. The extracted phytate gave high scavenging activity that reached 90% if compared with pure phytic acid. Aqueous wheat bran extract gave a percentage of free radical scavenging activity reached 36.16%. From the obtained results it can be concluded that phytate extracted from wheat bran has good antimicrobial and antioxidant activity and could be use as natural preservatives.","PeriodicalId":139703,"journal":{"name":"Journal of Sohag Agriscience (JSAS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128060366","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}

Five actinophage isolates specific to Streptomyces deserti were successfully isolated from two different locations of reclaimed soil in Sohag Governorate. Electron micrographs of the isolated phages indicated that all the phage isolates appeared to be head-and-tail types. The five phage isolates were designated ФSD1, ФSD2, ФSD3, ФSD4 and ФSD5. Phage isolates were characterized using optimum multiplicity and found to be 1.0 PFU/CFU for phage isolates ФSD1, ФSD2 and ФSD3 and 0.5 PFU/CFU for ФSD4 and ФSD5. One-step growth curves were studied; all phage isolates had the same infection cycle period; the differences were in the latent period, rise period, and burst size. The thermal inactivation point of each phage isolate was studied. All phage isolates exhibited tolerance to high temperature, since they kept their activity at 100 °C for 10 minutes. The host range of all phage isolates was examined using fourteen Streptomyces spp . isolates; the optimum pH for phage infection was found to be pH 7, and the phage isolates are tolerant of alkalinity and sensitive to acidity.","PeriodicalId":139703,"journal":{"name":"Journal of Sohag Agriscience (JSAS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134231965","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 start of warming weather seems to be the favorable condition for development and multiplication of the cowpea aphid, Aphis Craccivora Koch. In addition, the rapid increase of the pest during the vegetative growth of the plants might be related to suitability of the host plants in these stages. Four species of primary parasitoids; Aphidius colemani Viereck, Aphidus matricaria (Haliday), Diaretella rapae (M'Intosh) and Paraon necans (Mackauer) were recorded and identified belonging to family Aphidiidae.

Five treatments of fertilization (chemical \"inorganic\") as a control – (organic) – (organic + Biochar) – (organic + fungus “VA-mycorrhiza”) – (organic + bacteria “Bacillus”) were used in this study. Results revealed that there were significant differences between the fertilization treatments in all studied characteristics except leaf fresh weight (g), fruit length (cm), number of fruits plant -1 and total soluble solids (%). The results showed that the organic with bio fertilizers gave the best results in all studied characteristics and were not significantly different from chemical (inorganic) fertilization. Fertilization treatment (organic + bacteria) was the best in yield and quality characteristics. Fertilization treatment (organic + fungus) was the best in some vegetative growth traits such as relative growth rate (g g -1 day -1 ) and net assimilation rate (g m -2 day -1 ). Therefore, the study recommends the use of organic fertilizers with bio fertilizers, especially (organic + bacteria) to obtain the highest yield and quality of cucumber fruits. Thus, it is possible to preserve the soil, ground water and air from pollution by fertilizer residues, which achieves the main objective of the study, which is to preserve the environment from pollution, as well as to obtain safe healthy food. The study also recommends conducting more studies on the use of this type of fertilizer in different quantities and for other cultivars and on other crops under greenhouse conditions.

It was intended to determine the effect of exogenous proline addition on the vegetative growth and chemical compositions of Inga edulis seedlings grown under salt stress conditions. Seedlings were treated with proline at 100 and 200 ppm as a foliar spray either with or without salinity at 2000, 4000 and 6000 NaCl + CaCl 2 . In both seasons, different plant growth stem and root length, fresh and parameters and chemical compositions were significantly affected by proline and salinity with or without proline. However, seedlings sprayed with proline often had greater growth parameters as dry weight of stem and roots as well as a number of leaves than those of other treatments. Also, the highest values of nitrogen, phosphorus, potassium, chlorophyll a & b contents were noticed with proline treatments. The addition of proline at 100 and 200 ppm with 2000 ppm salinity produced vigor seedlings compared to the control. Meanwhile, the addition proline with salinity at 4000 or 6000 ppm did not exhibit a pronounced effect on the growth and chemical compositions compared to the control in both seasons. Seedling vigor and its chemical composition was reduced in response to salt stress without proline addition, while proline content in leaves was raised. These findings suggest that addition proline treatments can ameliorate the negative effects of salinity as NaCl + CaCl 2 on the growth and chemical compositions of Inga edulis seedlings.","PeriodicalId":139703,"journal":{"name":"Journal of Sohag Agriscience (JSAS)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123434967","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}
