“…Saccharomyces serevisiae is promising plant growth-promoting for different crops as descriped by Karajeh (2013). S. cerevisiae was investigated as a biocontrol agent against root-knot nematode by Noweer and Hasabo (2005); Karajeh (2013) and Mokbel and Alharbi (2014).…”

“…They showed that, the yeast was reduced root gall formation, egg masses and nematode reproduction ability and inhanced plant growth and fruit yield. High content of total phenolic and hydrogen peroxide in roots of S. cerevisiaetreated plants gives a clue on the ability of the yeast to induced plant resistance (Karajeh, 2013).…”

“…Due to environmental concerns and increased regulations on use of chemical nematicides, more effective management strategies for root-knot nematodes are currently being investigated (Noling and Backer, 1994). Among the biological control agents that have been assessed are antagonistic bacteria, nematophgous fungi and yeasts (Kiewnick andSikora, 2005 andKarajeh, 2013).…”

The survey conducted to assess the incidence of root-knot nematode on pomegranate in five localities (El-Badary, Manfalout, Sedfa, Sahel-Selim and El-Fath) in Assiut governorate. Results showed that 490 out of 500 samples were infested with root-knot nematode showing 98% infestation. Maximum infestation was found in El-Badary, Manfalout and El-Fath (100%), while the minimum was observed in Sahel-Selim (94%) followed by Sedfa (96%). In growing season 2013, the highest occurrence of root-knot nematode second stage was in pomegranate orchards of Sahel-Selim locality (394 J2/100 g soil), but the lowest number was found in Sedfa county (88.8 J2/100 g soil). In 2014, the highest number of juveniles per 100 g soil was observed in El-Fath county (275.4), whereas Manfalout county was the lowest infection (134.2). Bioagents (fungi, bacteria, yeast and actinomycetes) were isolated from pomegranate rhizosphere and evaluated against root-knot nematode J2 mortality percent in vitro. Among 29 fungal culture filtrates, the highest effect was found in culture filtrate of 3 isolates (2, 3 and 10) with average mortality percent 8.33, 10.01 and 9.22, respectively with nonsignificant. The fungal isolate No. 3 was selected and identified as Fusarium verticilloids. From 17 isolates of bacteria, yeast and actinomycetes, the highest mortality was observed in case of isolates No. 8, 9, 10, 11, 12, 15 and 16 with average 24.22, 23.69, 25.59, 25.82, 26.52, 22.13 and 25.24 mortality percent respectively, with nonsignificantly difference. According to morphological and physiological characteristics, isolates No. 10, 11, 12 and 16 were identified as Xenorhabdus beddingii, Streptomyces halstedii, Pantoea agglomerans and Pichia guilliermondii.

“…The bread yeast was more effective in reducing root-knot nematode, M. javanica on cucumber (Karajeh, 2013) and on squash (Noweer & Hasabo, 2005) when applied at 10g than rate of 5g/l. The bread yeast containing S. cerevisiae was as effective as the nematicide, oxamyl when applied as soil drench for controlling M. javanica on tomato cv.…”

“…Saccharomyces cerevisiae was used for controlling root-knot nematode, Meloidogyne javanica (Treub, 1885) Chitwood, 1949 on cucumber and on tomato (Karajeh, 2013;2014), respectively which led to reduction in numbers of galls and egg-masses. No studies were carried out on the effect of different sugar or yeast concentrations on root-knot nematode and plant growth.…”

Active dry bread yeast containing fungus, Saccharomyces cerevisiae was used as a bio-agent for controlling rootknot nematode, Meloidogyne incognita on eggplant under screen house conditions. Three solutions of yeast and sucrose (as a bio-fermentor) at different yeast concentrations (1, 2 & 3% yeast) + a fixed concentration of 2% sucrose and three solutions of sucrose and yeast at different sucrose concentrations (2, 3 & 4% sucrose), a fixed concentration of 2% yeast were applied. The results indicated that there was a positive correlation (R= 0.097) between average percentage nematode reduction and the applied concentrations of yeast or sucrose. The highest concentrations of bread yeast and sucrose (3%yeast +2% sucrose) and sucrose+bread yeast solution (4% sucrose+2% yeast) achieved the highest average percentages nematode reduction of 86% and 87.4%, respectively. On the other hand, eggplant growth parameters were the best by using 2% yeast + 2% sucrose or 2% sucrose + 2% yeast as growth index was 15.4. However, the highest concentration of yeast +sucrose solution (3% yeast + 2% sucrose) or sucrose + bread yeast solution (4% sucrose + 2% yeast) caused less growth indices compared to untreated check.

Microbial microencapsulation not only protects microorganisms from harmful environments by physically isolating them from the outside media but also has the potential to tailor the release profile of the encapsulated cells. However, the microbial release has not yet been controlled tightly, leading to undesired detrimental exposure of microorganisms to the outside. In this work, we suggest a simple method for controlling the cell release by suppressing the microbial growth in the microbeads. Alginate microbeads, encapsulating yeast cells, were coated with ultrathin but robust polydopamine shells, and the resulting core/shell structures effectively reduced the growth rate, while maintaining the cell viability.
