On the Markov property of strong solutions to SDE with generalized coefficients

We show the complete proof of the Markov property of the strong solution to a multidimensional SDE whose coefficients involve local time on a hyperplane of the unknown process

Investigation of the Influence of Antimicrobial Preparations on the Shelf Life of Broccoli Cabbage

Studies of the effect of antimicrobial agents on the conservation of broccoli cabbage have been conducted. The late hybrids of broccoli Ironman F1, Agassi F1, Beaumont F1, grown under the conditions of the Forest-Steppe of Ukraine were studied. The content of the main components of the chemical composition (dry substances, dry soluble substances, sugars, vitamin C) of broccoli cabbage is analyzed depending on the characteristics of the hybrid. The effect of antimicrobial treatment on the natural loss of cabbage, microbiological lesions during storage has been studied. Antimicrobial preparations Baikal EM-1 (dilution of working solution in water 1: 500), 0.5 % solution of citric, 0.2 % benzoic, 0.05 % sorbic acid, and also 0.5:0.5 % solution of vitamins C and P (ascorutin), water for the preparation of solutions had a temperature of 23 ... 25 °C.The processing of fruit and vegetable products with various chemicals is aimed at prolonging the shelf life, increasing the shelf life and increasing the yield of commercial products at the end of storage.It is established that the natural loss of broccoli cabbage during storage depends on the characteristics of the hybrid and the type of antimicrobial preparation. Treatment with preparations increases the shelf life of broccoli cabbage to 30 - 50 days with a natural weight loss of up to 6.1 %, and ensures minimal disease burden.Treatment with antimicrobial agents reduces the loss of dry substances, dry soluble substances, sugars, vitamin C. The most effective is the treatment of broccoli with acids. It has been established that ascorbic acid is contained in broccoli cabbage, with hydrolysis from which ascorbic acid is split off, the content of which is increased.The maximum effective storage of broccoli cabbage at a temperature of 0 ± 1 oС and relative humidity of 90-95 %, pretreatment with preparations of antimicrobial action.The proposed method of processing broccoli cabbage with antimicrobial preparations before storage allows the use of vegetable raw materials for post-harvest treatment. In the development of new, low-cost, environmentally friendly and affordable storage technologies, this is an important technique

Draft Genome of Janthinobacterium sp. RA13 Isolated from Lake Washington Sediment.

Sequencing the genome of Janthinobacterium sp. RA13 from Lake Washington sediment is announced. From the genome content, a versatile life-style is predicted, but not bona fide methylotrophy. With the availability of its genomic sequence, Janthinobacterium sp. RA13 presents a prospective model for studying microbial communities in lake sediments

Draft genomes of two strains of flavobacterium isolated from lake washington sediment.

We report sequencing the genomes of two new Flavobacterium strains isolated from Lake Washington sediment. From genomic contents, versatile lifestyles were predicted but not bona fide methylotrophy. With the availability of their genomic sequences, the new Flavobacterium strains present prospective models for studying microbial communities in lake sediments

Draft Genome of Pseudomonas sp. Strain 11/12A, Isolated from Lake Washington Sediment.

We announce here the genome sequencing of Pseudomonas sp. strain 11/12A from Lake Washington sediment. From the genome content, a versatile lifestyle is predicted but not one of bona fide methylotrophy. With the availability of its genomic sequence, Pseudomonas sp. 11/12A presents a prospective model for studying microbial communities in lake sediments

Draft genome sequences of five new strains of methylophilaceae isolated from lake washington sediment.

We sequenced the genomes of five new Methylophilaceae strains isolated from Lake Washington sediment. We used the new sequences to sort these new strains into specific Methylophilaceae ecotypes, including one novel ecotype. The new genomes expand the known diversity of Methylophilaceae and provide new models for studying the ecology of methylotrophy

Survival, biofilm formation, and growth potential of environmental and enteric escherichia coli strains in drinking water microcosms

E. coli is the most commonly used indicator for faecal contamination in a drinking water distribution system (WDS). The assumption is that E. coli are of enteric origin and cannot persist for long outside their host, therefore acting as indicators of recent contamination events. This study investigates the fate of E. coli in drinking water; specifically addressing survival, biofilm formation under shear stress, and regrowth in a series of laboratory-controlled experiments. We show the extended persistence of three E. coli strains (two enteric and one soil isolate) in sterile and non-sterile drinking water microcosms, at 8 and 17°C, with T90 values ranging from 17.4 ± 1.8 to 149 ± 67.7 days, using standard plate counts and a series of (RT)-Q-PCR assays targeting 16S rRNA, tuf, uidA, and rodA genes and transcripts. Furthermore, each strain was capable of attaching to a surface and replicating to form biofilm in the presence of nutrients under a range of shear stress values (0.6, 2.0, and 4.4 dyn cm-2; BioFlux, Fluxion); however, cell numbers did not increase when drinking water was flowed over (t-test; p > 0.05). Finally, E. coli regrowth within drinking water microcosms containing PE-100 pipe-wall material was not observed in the biofilm or water phase using a combination of culturing and Q-PCR methods for E. coli. The results of this work highlight that when E. coli enters drinking water it has the potential to survive and attach to surfaces but that regrowth within drinking water or biofilm is unlikely
