Main conclusion The floral nectars were sucrose-dominant; however, nectar protein and amino acid contents differed, indicating that composition of nitrogenous compounds may vary considerably even between closely related plant species, irrespectively nectary structure. Numerous zoophilous plants attract their pollinators by offering nectar; an aqueous solution produced specialized secretory tissues, known as nectaries. Although many papers on nectaries already exist, there has been a little...
Members of the genus Bifidobacterium are anaerobic Gram-positive Actinobacteria, which natural inhabitants human and animal gastrointestinal tract. Certain bifidobacteria frequently used as food additives probiotic pharmaceuticals, because their various health-promoting properties. Due to enormous demand on bacteria, manufacture high-quality products containing living microorganisms requires rapid accurate identification specific bacteria. Additionally, isolation new industrial bacteria from...
The genus Lactobacillus includes, among others, casei, paracasei and rhamnosus, species that are collectively referred to as the casei group. Many studies have shown strains belonging this group may decrease lactose intolerance, effects of inflammatory bowel disease, diarrhea, constipation, food allergies even colon cancer. Moreover, evidences exists positive these bacteria on mucosal immunity blood cholesterol level. Because their beneficial influence human health, many them used additives...
Abstract It is widely believed that microorganisms belonging to L. casei group can have positive effects on the human body. Therefore, these bacteria are used in many industrial processes, including production of dietary supplements and probiotic preparations. When using live technological it important use those without phage sequences within their genomes ultimately lead lysis bacteria. has been shown prophages a benign nature, meaning they don’t directly or inhibit microbial growth....
Succinic acid (SA), a valuable chemical compound with broad range of industrial uses, has become subject global interest in recent years. The bio-based production SA by highly efficient microbial producers from renewable feedstock is significantly important, regarding the current trend sustainable development.In this study, novel bacterial strain, LU2, was isolated cow rumen and recognized as an producer lactose. Proteomic genetic identifications well phylogenetic analysis were performed,...
The ability of Rhizopus oryzae to produce fumaric acid in the presence glycerol and/or various monosaccharides as carbon sources was examined for seventeen different strains this fungi. These were tested shake-flask cultures on media containing and seven carbohydrates, including glucose, fructose, galactose, mannose, xylose, arabinose, rhamnose. An interesting applicationally useful phenomenon observed. This work presents a new approach conventional microbiological method producing acid. In...
The newly-isolated strain Enterobacter sp. LU1, which has previously been shown to be an effective producer of succinic acid on glycerol with the addition lactose, was used for further intensive works aimed at improving production parameters said process. introduction initial stage gentle culture aeration allowed almost 47 g/L obtained after 168 h incubation, is two times faster than time taken obtain this amount. Furthermore, replacement crude glycerin and lactose whey permeate final...
In dichogamous plants, nectar characteristics (i.e. amount and its composition) can differ between sexual phases. the present study, we investigated structural organization of floral nectary, production carbohydrate composition in protandrous Chamaenerion angustifolium ( L .) S cop. O nagraceae). The receptacular nectary consisted an epidermis with numerous nectarostomata, several layers photosynthetic secretory parenchyma, subsecretory parenchyma. Nectariferous tissue was not directly...
Phenylketonuria (PKU) is a metabolic disorder that necessitates dietary restrictions, potentially impacting the composition of gut and oral microbiota. This study aimed to compare microbiota between children with PKU healthy controls.
Lactobacillus rhamnosus Pen is a human endogenous strain with well-documented health promoting properties that used for production of probiotics. It has long safety history application, and its effectiveness in the prevention antibiotic-associated diarrhoea also been confirmed clinical trials.Here we present complete genome sequence L. Pen, which consists circular 2,884,4966-bp chromosome GC content 46.8%. Within 2907 open reading frames (ORFs), genes involved probiotic were identified. A...
Lactobacillus rhamnosus Pen is a human endogenous strain used for the production of probiotic formula, which effective in prevention antibiotic-associated diarrhoea. Our study showed that this releases bacteriophage BH1 without addition any inducing agent. research revealed phage has circular genome with length 40721 nt and GC content 44.8%. The possesses 57 open reading frames could be divided into functional modules associated DNA packaging, morphogenesis, lysis, integration, genetic...
Abstract Enterobacter aerogenes LU2 was isolated from cow rumen and recognized as a potential succinic acid producer in our previous study. Here, we present the first complete genome sequence of this new, wild strain report its basic genetic features biotechnological perspective. The MinION single-molecule nanopore sequencer supported by Illumina MiSeq platform yielded circular 5,062,651 bp chromosome with GC content 55% that lacked plasmids. A total 4,986 genes, including 4,741...
Streszczenie: Celem badań była ocena uzdolnień szczepów należących do rodzaju Rhizopus, pochodzących z kolekcji zagranicznych oraz izolatów ze środowisk naturalnych województwa lubelskiego, biosyntezy kwasu fumarowego glicerolu jako jedynego źródła węgla
Phenylketonuria (PKU) is a metabolic and genetic disorder caused by phenylalanine hydroxylase (PAH) gene deficiency that raises Phe levels in organs. Dietary therapy involves an elimination diet Phe-free items, which may alter microbiota. The study examined the oral intestinal microbiomes of 63-year-old PKU patient control man, living rural areas. iSeq100 (Illumina) sequenced stool 16S rRNA V3-V4 region. guts had more Firmicutes fewer Bacteroidetes than control. Clostridia predominated PKU,...
Celem pracy była ocena zdolności nowo wyizolowanych szczepów z rodzaju Rhizopus do produkcji kwasu mlekowego. W przypadku 20 izolatów, spośród 40 przebadanych, w filtratach pohodowlanych stwierdzono znaczące stężenia Były to szczepy zaliczone gatunku oryzae, podczas gdy pozostałe szczepy, tym należące stolonifer, tych uzdolnień nie przejawiały. Stężenia mlekowego były zróżnicowane zależności od użytego szczepu grzyba oraz źródła węgla. Najwyższe stężenie – 74,06 g/l oznaczono filtracie...
