Random mutations were induced for bacterial strains using ultraviolet (UV) and ethyl methanesulfonate (EMS). Moreover, protoplast fusion is an important tool in strain improvement to achieve genetic recombination and developing hybrid bacterial strains. The molecular analysis of mutants and fusants by random amplification of polymorphic DNA (RAPD-PCR) was done. Objective Streptomyces lavendulae R-St strain, which produces the highest LiP, was discovered and investigated in a previous study by the authors. It has been deposited in NCBI under the accession number ‘OL697233.1.’ S. lavendulae was used in the present study to produce novel, higher LiP-producing mutants using EMS-mutagenesis and UV light. Most mutant strains that produce LiP fuse their protoplasts. To assess the genetic diversity of isolated S. lavendulae R-St-1 with its mutants and fusants, RAPD-PCR was used. Materials and methods Lignin was extracted and purified from black wood liquor. UV and EMS were used for creating super LiP-producing mutants of S. lavendulae R-St. Protoplast fusion between EMS and UV-treated mutants was performed for isolating LiP-productive fusants (s) from S. lavendulae R-St-1 as the original isolate. Fermentation medium (FM) (g/l) was used for lignin-degrading bacterial screening after dilution of the soil samples: K2HPO4, 4.55, KH2PO4, 0.53, MgSO4,0.5, NH4NO3, 0.1, yeast extract, 0.1, lignin (0.1% v/v), agar 15, and the pH should be 7.0. The aforementioned FM medium was supplemented with 50 mg/l of azure B and toluidine dyes and 100 mg/l of tannic acid. FM was used without any supplements and agar for the isolation of lignin-degrading bacteria using lignin (0.1% v/v). The molecular analysis of mutants by RAPD-PCR was applied using different primers, and different separate bands were determined. Results and discussion S. lavendulae R-St-1 strain was mutagenized with alkylating EMS (200 mm) and UV. Results showed that from the S. lavendulae R-St-1 (W.T) isolate, two EMS-treated mutants (Rst/60/7E and Rst/40/8E), which showed activities of 8.5 and 7.3 U/ml, respectively, and two UV-treated mutants (Rst/9/2U and Rst/9/6U), which showed activities of 9.4 and 7.8 U/ml, respectively, were the most efficient ligninolytic mutants. Protoplast fusion between two higher LiP-producing mutants (cross 1 and 2) proved to be the most effective, and the two isolated fusants C1/St/5 and C1/St/6 showed activity of 12.8 and 11.8 U/ml, respectively, after protoplast fusion between Rst/9/6U and Rst/60/7E mutants of S. lavendulae R-St-1 (W.T). To determine molecular variability of two EMS mutants, and their recombinant fusants as well as S. lavendulae (W.T) (parental), three random primers were used. RAPD primer (P1) was employed. Fusant C1/St/5 shared the parental isolate with the bands 850 and 300 bp, wher","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":"22 1","pages":"111 - 122"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46631921","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 caraway seeds are regarded as antispasmodic, astringent, and carminative, and are used in treating somatic stimulants, dyspepsia, colic, flatulent indigestion, diarrhea, and improved liver function. Tissue culture is a suitable strategy for producing large-scale plantlets with a high potential to produce superior-quality plants. Plant transformation methods help to improve food quality and help plants to resist biotic and abiotic stresses. The current study aimed to optimize in vitro propagation system and genetic transformation protocol by using the Agrobacterium-mediated method for caraway. Materials and methods The shoot tip was used as an explant. We investigated the effect of growth hormones, carbon sources, gelling agents, bacteria optical density, inoculation period, acetosyringone concentration, and cocultivation period on caraway regeneration and transformation system. Results and conclusion Maximum shoot response, numbers of shoots per explant, and shoot length were observed when placing shoot tips on Murashige and Skoog media supplemented with 5 μmol/l BA (6-benzyladenin), 1 μmol/l NAA (1-naphthaleneacetic acid), and 30 g/l of sucrose. Gellan gum products (gelrite and phyta gel) were superior to agar products (agar and bactoagar), especially when used with a concentration of 2.5 or 3 g/l. For transformation protocol, Agrobacterium infection was maximum at an optical density of 0.8 when inoculated with explant for 5 min in the presence of 100 μmol/l acetosyringone and cocultivated for 3 days.

Therefore, recent studies have focused on the enhancement of LS production through searching for potent microbial producers and optimization of the fermentation conditions. The present study aimed to use agro-industrial waste as a cost-effective carbon source for LS production and maximize the enzyme yield by optimization of the cultural conditions. Materials and methods A potent fungal producer of LS was isolated from an Egyptian soil sample that was collected from Giza Governorate at a depth of 5 cm and identified based on internal transcribed spacer identification and then submitted to the gene bank database. The production of LS by the isolated strain was optimized by evaluating the best fermentation state and agro-industrial waste to be used in the fermentation process. After that, further optimization of culture medium composition was established by two statistical designs: the Plackett–Burman design followed by central composite design. Results and conclusion The isolated strain was identified as Aspergillus niger MK788296. The first optimization approach declared that using the submerged fermentation technique and utilizing potato peels as the main carbon source led to a 2.4-fold increase in LS production. The statistical optimization resulted in a massive LS production (18870.3 U/ml) with a 59.4-fold increase in enzyme yield than the nonoptimized culture conditions.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":"22 1","pages":"38 - 48"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49320961","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}

Objective In this study, we aimed to evaluate the probable antipsychotic effect of pupae of mulberry silkworms in a rat model of schizophrenia prompted by ketamine on the cerebral cortex, hippocampus, and striatum, the brain areas involved in neuropsychiatric complaints. Materials and methods To this end, male albino rats were classified as follows: group 1 was the control group; group 2 animals were administered 135 mg/kg, p.o. silkworm pupae for 3 weeks; group 3 animals received vehicle for 3 weeks, and ketamine (30 mg/kg, i.p.) for the last 5 consecutive days of the experiment; and group 4 was the silkworm pupae and ketamine-treated group. Results The results revealed that treatment with silkworm pupae improved the exploration of schizophrenic rats in the novel object test and almost normalized their locomotor activity in the open field test. Additionally, silkworm pupae modulated the content of catecholamines and oxidative state in the cerebral cortex, hippocampus, and striatum of schizophrenic rats; however, the acetylcholine esterase activity was restored in the hippocampus only. Histopathological damages caused by ketamine are partially reduced by silkworm pupae.

Objective The objective of our study was to isolate, characterize, and identify a probiotic bacterial strain and determine its hypoglycemia operating parameters. Materials and methods Our research was carried out through the isolation of probiotic colonies from milk samples on MRS medium. Bacterial isolates were characterized both morphologically and biochemically. The collected bacterial isolates were tested for their low pH tolerance on phosphate buffer pH 2.0 and bile salt tolerance in MRS-THIO liquid medium. Glucose assimilation activity was tested by measuring the residual glucose concentration on MRS liquid medium at 37°C after 24 and 48 h by GOD-PAP enzymatic colorimetric method. The initial glucose concentration was 500 mg/dl. The most potent isolate was identified by methods of 16S-rDNA sequencing. Results and conclusion Twenty-one bacterial isolates were isolated and characterized. Bacterial isolates showed the highest resistance to acidic pH 2.0 and they were bile-tolerant. Results of glucose assimilation showed that there was a marked increase in sugar consumption rate after 48 h more than 24 h in most of the bacterial isolates. The top 10 isolates were selected for the testing of the rest of the parameters. Results show that no noticeable differences were observed in the consumption of glucose in the low-glucose concentration, but with more glucose concentration more glucose consumption rate differences were recorded among organisms. The top two organisms that have the ability to reproduce and consume glucose even in high-glucose concentrations were Ab 9 and Ab 2 with results of glucose residual concentration of 108 and 124 mg/dl, respectively.

UTIs can be caused by a variety of pathogens, but Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Proteus mirabilis are the most frequent culprits. The growth and development of antibiotic-resistant bacteria are currently a major worry for the international health community. Looking for a treatment substitute could be effective in tackling this issue. The honey has a low pH (mean 4.4) value, which makes it unfavorable for bacterial growth; undiluted honey combination with silver nanoparticles (AgNPs) shows synergistic antimicrobial effect and helps lessen infection. Aim This study was undertaken to find out the effectiveness of honey containing AgNPs in the antibacterial activity of isolated urine pathogens. Patients and methods A total of 30 patients with UTI were included through purposive sampling technique, and urine samples were collected from them. A semiquantitative approach was used to cultivate specimens of urine on MacConkey agar and blood agar. After 24 h of incubation, bacterial growth was seen on the plates. Then, colonies were counted and the number of microorganisms per milliliter in the original material was calculated by multiplying the number of CFUs by 1000. Results A total of 10 bacterial isolates were found in the 30 urine samples, and biochemical studies showed that these isolates were from three different species. The most common strain of E. coli represented 82%, followed by P. aeruginosa (12%) and P. mirabilis (6%). In all three organisms examined with undiluted honey mixed with AgNPs, the zone of inhibition was more pronounced when compared with only honey, AgNPs, and diluted honey mixed with AgNPs.

Lipases are used as biological catalysts to manufacture products such as food ingredients and applied in making fine chemicals. The type of lipase produced from microbes, mainly from bacteria and fungi, represents the most widely used class of enzymes in biotechnological applications and organic chemistry. Microbial enzymes are also more stable than their corresponding plant and animal enzymes, and their production is more convenient and safer, which makes them more important in commercial uses. The oily environment of vegetable oil-processing factories, industrial wastes, soil contaminated with oil, and diesel fuel-polluted soil provides a suitable habitat for lipase-producing microorganisms. Objective This study aims to detect new strains of lipase-producing bacteria from diverse sources and different areas in Jeddah, Saudi Arabia. Furthermore, the detected bacterial strains have been identified based on morphological, biochemical, and molecular characterization. The plasmid profile of some isolated bacterial strains has been detected. Materials and methods A total of 36 soil samples contaminated with fuel and engine oil were collected from different areas in Jeddah, Saudi Arabia. Tween 20 medium was used to detect the lipolytic activity of the bacterial strains. The isolated bacteria in this study were identified by morphological and biochemical tests and 16SrRNA. Results and discussion Results showed that 53 isolates were positive and able to produce lipase, and 15 isolates have been selected as strong lipase-producing bacteria.
